# GNU AFFERO GENERAL PUBLIC LICENSE
Version 3, 19 November 2007
Copyright (C) 2007 Free Software Foundation, Inc.
<https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
## Preamble
The GNU Affero General Public License is a free, copyleft license for
software and other kinds of works, specifically designed to ensure
cooperation with the community in the case of network server software.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
our General Public Licenses are intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains
free software for all its users.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
Developers that use our General Public Licenses protect your rights
with two steps: (1) assert copyright on the software, and (2) offer
you this License which gives you legal permission to copy, distribute
and/or modify the software.
A secondary benefit of defending all users' freedom is that
improvements made in alternate versions of the program, if they
receive widespread use, become available for other developers to
incorporate. Many developers of free software are heartened and
encouraged by the resulting cooperation. However, in the case of
software used on network servers, this result may fail to come about.
The GNU General Public License permits making a modified version and
letting the public access it on a server without ever releasing its
source code to the public.
The GNU Affero General Public License is designed specifically to
ensure that, in such cases, the modified source code becomes available
to the community. It requires the operator of a network server to
provide the source code of the modified version running there to the
users of that server. Therefore, public use of a modified version, on
a publicly accessible server, gives the public access to the source
code of the modified version.
An older license, called the Affero General Public License and
published by Affero, was designed to accomplish similar goals. This is
a different license, not a version of the Affero GPL, but Affero has
released a new version of the Affero GPL which permits relicensing
under this license.
The precise terms and conditions for copying, distribution and
modification follow.
## TERMS AND CONDITIONS
### 0. Definitions.
"This License" refers to version 3 of the GNU Affero General Public
License.
"Copyright" also means copyright-like laws that apply to other kinds
of works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of
an exact copy. The resulting work is called a "modified version" of
the earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user
through a computer network, with no transfer of a copy, is not
conveying.
An interactive user interface displays "Appropriate Legal Notices" to
the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
### 1. Source Code.
The "source code" for a work means the preferred form of the work for
making modifications to it. "Object code" means any non-source form of
a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users can
regenerate automatically from other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same
work.
### 2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not convey,
without conditions so long as your license otherwise remains in force.
You may convey covered works to others for the sole purpose of having
them make modifications exclusively for you, or provide you with
facilities for running those works, provided that you comply with the
terms of this License in conveying all material for which you do not
control copyright. Those thus making or running the covered works for
you must do so exclusively on your behalf, under your direction and
control, on terms that prohibit them from making any copies of your
copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the
conditions stated below. Sublicensing is not allowed; section 10 makes
it unnecessary.
### 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such
circumvention is effected by exercising rights under this License with
respect to the covered work, and you disclaim any intention to limit
operation or modification of the work as a means of enforcing, against
the work's users, your or third parties' legal rights to forbid
circumvention of technological measures.
### 4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
### 5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these
conditions:
- a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
- b) The work must carry prominent notices stating that it is
released under this License and any conditions added under
section 7. This requirement modifies the requirement in section 4
to "keep intact all notices".
- c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
- d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
### 6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of
sections 4 and 5, provided that you also convey the machine-readable
Corresponding Source under the terms of this License, in one of these
ways:
- a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
- b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the Corresponding
Source from a network server at no charge.
- c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
- d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
- e) Convey the object code using peer-to-peer transmission,
provided you inform other peers where the object code and
Corresponding Source of the work are being offered to the general
public at no charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal,
family, or household purposes, or (2) anything designed or sold for
incorporation into a dwelling. In determining whether a product is a
consumer product, doubtful cases shall be resolved in favor of
coverage. For a particular product received by a particular user,
"normally used" refers to a typical or common use of that class of
product, regardless of the status of the particular user or of the way
in which the particular user actually uses, or expects or is expected
to use, the product. A product is a consumer product regardless of
whether the product has substantial commercial, industrial or
non-consumer uses, unless such uses represent the only significant
mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to
install and execute modified versions of a covered work in that User
Product from a modified version of its Corresponding Source. The
information must suffice to ensure that the continued functioning of
the modified object code is in no case prevented or interfered with
solely because modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or
updates for a work that has been modified or installed by the
recipient, or for the User Product in which it has been modified or
installed. Access to a network may be denied when the modification
itself materially and adversely affects the operation of the network
or violates the rules and protocols for communication across the
network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
### 7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders
of that material) supplement the terms of this License with terms:
- a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
- b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
- c) Prohibiting misrepresentation of the origin of that material,
or requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
- d) Limiting the use for publicity purposes of names of licensors
or authors of the material; or
- e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
- f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions
of it) with contractual assumptions of liability to the recipient,
for any liability that these contractual assumptions directly
impose on those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions; the
above requirements apply either way.
### 8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your license
from a particular copyright holder is reinstated (a) provisionally,
unless and until the copyright holder explicitly and finally
terminates your license, and (b) permanently, if the copyright holder
fails to notify you of the violation by some reasonable means prior to
60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
### 9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run
a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
### 10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
### 11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims owned
or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within the
scope of its coverage, prohibits the exercise of, or is conditioned on
the non-exercise of one or more of the rights that are specifically
granted under this License. You may not convey a covered work if you
are a party to an arrangement with a third party that is in the
business of distributing software, under which you make payment to the
third party based on the extent of your activity of conveying the
work, and under which the third party grants, to any of the parties
who would receive the covered work from you, a discriminatory patent
license (a) in connection with copies of the covered work conveyed by
you (or copies made from those copies), or (b) primarily for and in
connection with specific products or compilations that contain the
covered work, unless you entered into that arrangement, or that patent
license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
### 12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under
this License and any other pertinent obligations, then as a
consequence you may not convey it at all. For example, if you agree to
terms that obligate you to collect a royalty for further conveying
from those to whom you convey the Program, the only way you could
satisfy both those terms and this License would be to refrain entirely
from conveying the Program.
### 13. Remote Network Interaction; Use with the GNU General Public License.
Notwithstanding any other provision of this License, if you modify the
Program, your modified version must prominently offer all users
interacting with it remotely through a computer network (if your
version supports such interaction) an opportunity to receive the
Corresponding Source of your version by providing access to the
Corresponding Source from a network server at no charge, through some
standard or customary means of facilitating copying of software. This
Corresponding Source shall include the Corresponding Source for any
work covered by version 3 of the GNU General Public License that is
incorporated pursuant to the following paragraph.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the work with which it is combined will remain governed by version

# NVIDIA vGPU on PVE 7.1 with a NVIDIA T1000 GPU
# NVIDIA vGPU on Proxmox
This tutorial (and included patches) should allow you to use vGPU unlock on PVE 7.1 with the opt-in 5.15 Linux Kernel with a NVIDIA T1000 GPU. The GPU uses the TU117 Chip so other GPUs with the same Chip (T400, T600, GTX 1650 **NOT** Super) will probably work (no guarantees).
### This tutorial assumes you are using a clean install of PVE 7.1, or ymmv when using an existing installation. Make sure to always have backups!
This document serves as a guide to install NVIDIA vGPU host drivers on the latest Proxmox VE version, at time of writing this its pve 8.3.
You can follow this guide if you have a vGPU supported card from [this list](https://docs.nvidia.com/grid/gpus-supported-by-vgpu.html), or if you are using a consumer GPU from the GeForce series or a non-vGPU qualified Quadro GPU. There are several sections with a title similar to "Have a vgpu supported card? Read here"" in this document, make sure to read those very carefully as this is where the instructions differ for a vGPU qualified card and a consumer card.
## Supported cards
The following consumer/not-vGPU-qualified NVIDIA GPUs can be used with vGPU:
- Most GPUs from the Maxwell 2.0 generation (GTX 9xx, Quadro Mxxxx, Tesla Mxx) **EXCEPT the GTX 970**
- All GPUs from the Pascal generation (GTX 10xx, Quadro Pxxxx, Tesla Pxx)
- All GPUs from the Turing generation (GTX 16xx, RTX 20xx, Txxxx)
Starting from driver version 17.0, Pascal and earlier require additional patches, see [below](#psa-for-pascal-and-older-gpus-like-the-p4-gtx-1080) for more!
If you have GPUs from the Ampere and Ada Lovelace generation, you are out of luck, unless you have a vGPU qualified card from [this list](https://docs.nvidia.com/grid/gpus-supported-by-vgpu.html) like the A5000 or RTX 6000 Ada. If you have one of those cards, please consult the [NVIDIA documentation](https://docs.nvidia.com/grid/15.0/grid-vgpu-user-guide/index.html) for help with setting it up.
> **!!! THIS MEANS THAT YOUR RTX 30XX or 40XX WILL NOT WORK !!!**
This guide and all my tests were done on a RTX 2080 Ti which is based on the Turing architechture.
## Important notes before starting
- This tutorial assumes you are using a clean install of Proxmox VE 8.3.
- If you are using Proxmox VE 8.3, you **MUST** use 16.x or 17.x drivers. Older versions only work with pve 7
- If you tried GPU-passthrough before, you absolutely **MUST** revert all of the steps you did to set that up.
- If you only have one GPU in your system with no iGPU, your local monitor will **NOT** give you any output anymore after the system boots up. Use SSH or a serial connection if you want terminal access to your machine.
- Most of the steps can be applied to other linux distributions, however I'm only covering Proxmox VE here.
> ## Are you upgrading from a previous version of this guide?
>
> If you are upgrading from a previous version of this guide, you should uninstall the old driver by running `nvidia-uninstall` first.
>
> Then you also have to make sure that you are using the latest version of `vgpu_unlock-rs`, otherwise it won't work with the latest driver.
>
> Either delete the folder `/opt/vgpu_unlock-rs` or enter the folder and run `git pull` and then recompile the library again using `cargo build --release`

PVE 7.1 comes with version 5.13 of the Linux Kernel, that version is incompatible with vGPU. For this guide you will have to install version 5.15, which will probably come with PVE 7.2 (~Q2 2022) but is opt-in on current PVE versions

## Enabling IOMMU
#### Note: Usually this isn't required for vGPU to work, but it doesn't hurt to enable it. You can skip this section, but if you run into problems later on, make sure to enable IOMMU.
Assuming you installed PVE with ZFS-on-root and efi, you are booting with systemd-boot. All other installations use grub. The following instructions *ONLY* apply to systemd-boot, grub is different.
To enable IOMMU you have to enable it in your BIOS/UEFI first. Due to it being vendor specific, I am unable to provide instructions for that, but usually for Intel systems the option you are looking for is called something like "Vt-d", AMD systems tend to call it "IOMMU".
To enable IOMMU you have to enable it in your UEFI first. Due to it being vendor specific, I am unable to provide instructions for that, but usually for Intel systems the option you are looking for is called something like "Vt-d", AMD systems tend to call it "IOMMU".
After enabling it in your BIOS/UEFI, you also have to enable it in your kernel. Depending on how your system is booting, there are two ways to do that.
After enabling IOMMU in your UEFI, you have to add some options to your kernel to enable it in proxmox. Edit the kernel command line like this
```bash
nano /etc/kernel/cmdline
```
If you installed your system with ZFS-on-root and in UEFI mode, then you are using systemd-boot, everything else is GRUB. GRUB is way more common so if you are unsure, you are probably using that.
On a clean installation the file might look similar to this:
```
root=ZFS=rpool/ROOT/pve-1 boot=zfs
```
Depending on which system you are using to boot, you have to chose from the following two options:
On Intel systems, append this line at the end
```
intel_iommu=on iommu=pt
```
<details>
<summary>GRUB</summary>
For AMD, use this
```
amd_iommu=on iommu=pt
```
Open the file `/etc/default/grub` in your favorite editor
```bash
nano /etc/default/grub
```
After editing the file, it should look similar to this
```
root=ZFS=rpool/ROOT/pve-1 boot=zfs intel_iommu=on iommu=pt
```
The kernel parameters have to be appended to the variable `GRUB_CMDLINE_LINUX_DEFAULT`. On a clean installation that line should look like this
```
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
```
Save and exit using Ctrl+O and then Ctrl+X
If you are using an Intel system, append this after `quiet`:
```
intel_iommu=on
```
On AMD systems, you don't have to add anything and amd_iommu=on does not exist:
https://www.kernel.org/doc/html/latest/admin-guide/kernel-parameters.html?highlight=amd_iommu
For either AMD or Intel there is an option incase you have heavy performance issues, but with the loss of security and stability of the system:
```
iommu=pt
```
The result should look like this (for intel systems):
```
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"
```
Now, save and exit from the editor using Ctrl+O and then Ctrl+X and then apply your changes:
```bash
update-grub
```
</details>
<details>
<summary>systemd-boot</summary>
The kernel parameters have to be appended to the commandline in the file `/etc/kernel/cmdline`, so open that in your favorite editor:
```bash
nano /etc/kernel/cmdline
```
On a clean installation the file might look similar to this:
```
root=ZFS=rpool/ROOT/pve-1 boot=zfs
```
On Intel systems, append this at the end
```
intel_iommu=on
```

## NVIDIA Driver
### Choosing the right driver version
This repo contains patches that allow you to use vGPU on not-qualified-vGPU cards (consumer GPUs). Those patches are binary patches, which means that each patch works **ONLY** for a specific driver version.
This is the tricky part, at the time of writing (Jan 2022), there are [three active branches](https://docs.nvidia.com/grid/) of the NVIDIA vGPU driver. The latest is branch 13 (long term support branch until mid 2024) with driver version 470. I had no luck getting *any* version of that driver to work with vGPU at all but as always - ymmv.
I've created patches for the following driver versions:
- 17.5 (550.144.02)
- 17.4 (550.127.06)
- 17.3 (550.90.05)
- 17.1 (550.54.16)
- 17.0 (550.54.10)
- 16.9 (535.230.02) !!! USE THIS IF YOU ARE ON PASCAL OR OLDER !!!
- 16.8 (535.216.01)
- 16.7 (535.183.04)
- 16.5 (535.161.05) the patch for this version is the same as for 16.4, the host driver wasnt changed in this release
- 16.4 (535.161.05)
- 16.2 (535.129.03)
- 16.1 (535.104.06)
- 16.0 (535.54.06)
Branch 12 is a "regular" production branch with support until January of 2022 and has driver version number 460. Lots of people are running that driver in combination with the Linux Kernel 5.15. I got it installed with my gpu, but as soon as I tried to use the gpu in my VM, the display would freeze every 30-ish seconds and `nvidia-vgpu-mgr.service` would report an error similar to `error: vmiop_log: (0x0): XID 43 detected on physical_chid:0x1c, guest_chid:0x14`. At first I thought I messed up some of the driver patches required to get the driver working on kernels newer than 5.11 - so I tried on PVE 6.4 without any patches (5.4 kernel) but got the same errors there. If anyone knows what's causing this error, or even how to fix it, **please** let me know :)
Driver support by nvidia:
- 16.x is the LTS branch, with official support until July 2026
- 17.x has official support until February 2025
Ruling out those two branches only leaves the older long term support branch 11: It is supported until mid 2023 and has the driver version 450. Like the other branch (12), you have to patch some parts of the driver to get it working on the Linux Kernel 5.15. I tried every patch I could find on the Internet (mostly twelve.patch and fourteen.patch and their variations) but no combination of them allowed me to install the driver - the installer would always complain about my system being incompatible. So I spent a few hours looking at the existing patches and reviewing the files they patch to finally come up with my own patch: Basically, it adapts twelve.patch and fourteen.patch to this older driver (they seem to be designed for the branch 12 driver) and merges them into a single patch.
> ### The following versions are EOL, don't use them unless you have a very specific reason!

You can choose which of those you want to use, but generally its recommended to use the latest, most up-to-date version (17.5 in this case), unless you have a pascal series GPU or older, then use the latest 16.x driver.
If you have a vGPU qualified GPU, you can use other versions too, because you don't need to patch the driver. However, you still have to make sure they are compatible with your proxmox version and kernel. Also I would not recommend using any older versions unless you have a very specific requirement.
### Obtaining the driver
I will be using the latest driver from branch 11 (at the time of writing that would be 11.6 / 450.156).
NVIDIA doesn't let you freely download vGPU drivers like they do with GeForce or normal Quadro drivers, instead you have to download them through the [NVIDIA Licensing Portal](https://nvid.nvidia.com/dashboard/) (see: [https://www.nvidia.com/en-us/drivers/vgpu-software-driver/](https://www.nvidia.com/en-us/drivers/vgpu-software-driver/)). You can sign up for a free evaluation to get access to the download page.
After downloading version 11.6 you should have a zip file called `NVIDIA-GRID-Linux-KVM-450.156-450.156.00-453.23.zip`, extract that and copy the file `NVIDIA-Linux-x86_64-450.156-vgpu-kvm.run` to your PVE host into the `/root/` folder
```bash
scp NVIDIA-Linux-x86_64-450.156-vgpu-kvm.run root@pve:/root/
```
NB: When applying for an eval license, do NOT use your personal email or other email at a free email provider like gmail.com. You will probably have to go through manual review if you use such emails. I have very good experience using a custom domain for my email address, that way the automatic verification usually lets me in after about five minutes.
I've created a small video tutorial to find the right driver version on the NVIDIA Enterprise Portal. In the video I'm downloading the 15.0 driver, if you want a different one just replace 15.0 with the version you want:
![Video Tutorial to find the right driver](downloading_driver.mp4)
After downloading, extract the zip file and then copy the file called `NVIDIA-Linux-x86_64-DRIVERVERSION-vgpu-kvm.run` (where DRIVERVERSION is a string like `550.144.02`) from the `Host_Drivers` folder to your Proxmox host into the `/root/` folder using tools like FileZilla, WinSCP, scp or rsync.
### ⚠️ From here on, I will be using the 17.5 driver, but the steps are the same for other driver versions
For example when I run a command like `chmod +x NVIDIA-Linux-x86_64-550.144.02-vgpu-kvm.run`, you should replace `550.144.02` with the driver version you are using (if you are using a different one). You can get the list of version numbers [here](#nvidia-driver).
Every step where you potentially have to replace the version name will have this warning emoji next to it: ⚠️

### Patching the driver
Now, on the proxmox host, make the driver executable
⚠️
```bash
chmod +x NVIDIA-Linux-x86_64-450.156-vgpu-kvm.run
chmod +x NVIDIA-Linux-x86_64-550.144.02-vgpu-kvm.run
```
And then unpack it
And then patch it
⚠️
```bash
./NVIDIA-Linux-x86_64-450.156-vgpu-kvm.run -x
./NVIDIA-Linux-x86_64-550.144.02-vgpu-kvm.run --apply-patch ~/vgpu-proxmox/550.144.02.patch
```
That should output a lot of lines ending with
```
Self-extractible archive "NVIDIA-Linux-x86_64-550.144.02-vgpu-kvm-custom.run" successfully created.
```
Go inside the extracted folder
```bash
cd NVIDIA-Linux-x86_64-450.156-vgpu-kvm/
```
To be able to install the driver on your proxmox host, apply the driver patch
```bash
patch -p0 < ~/vgpu-5.15/450_5.15.patch
```
If everything went right (and you are using the exact same nvidia driver version 11.6), the output should be exactly this
```
patching file ./kernel/Kbuild
patching file ./kernel/conftest.sh
patching file ./kernel/nvidia-vgpu-vfio/nvidia-vgpu-vfio.c
patching file ./kernel/nvidia-vgpu-vfio/nvidia-vgpu-vfio.h
patching file ./kernel/nvidia/nv-frontend.c
```
There is a second patch you need to apply.
#### Warning: If you followed every step of this tutorial it should be safe to just apply it, but if you did anything different than I, you should check if the paths in the patch are valid for you.
```bash
patch -p0 < ~/vgpu-5.15/unlock.patch
```
The output should be exactly this
```
patching file ./kernel/nvidia/nvidia.Kbuild
patching file ./kernel/nvidia/os-interface.c
```
You should now have a file called `NVIDIA-Linux-x86_64-550.144.02-vgpu-kvm-custom.run`, that is your patched driver.
### Installing the driver
Now that all the required patches are applied, you can install the driver
Now that the required patch is applied, you can install the driver

However, if you get this output, then something went wrong
```
No supported devices in vGPU mode
```
If any of those commands give the wrong output, you cannot continue. Please make sure to read everything here very carefully and when in doubt, create an issue or join the [discord server](#support) and ask for help there.
## vGPU overrides
Further up we have created the file `/etc/vgpu_unlock/profile_override.toml` and I didn't explain what it was for yet. Using that file you can override lots of parameters for your vGPU instances: For example you can change the maximum resolution, enable/disable the frame rate limiter, enable/disable support for CUDA or change the vram size of your virtual gpus.
If we take a look at the output of `mdevctl types` we see lots of different types that we can choose from. However, if we for example chose `GRID RTX6000-4Q` which gives us 4GB of vram in a VM, we are locked to that type for all of our VMs. Meaning we can only have 4GB VMs, its not possible to mix different types to have one 4GB VM, and two 2GB VMs.

All of that changes with the override config file. Technically we are still locked to only using one profile, but now its possible to change the vram of the profile on a VM basis so even though we have three `GRID RTX6000-4Q` instances, one VM can have 4GB or vram but we can override the vram size for the other two VMs to only 2GB.
Lets take a look at this example config override file (its in TOML format)
```toml
[profile.nvidia-259]
num_displays = 1 # Max number of virtual displays. Usually 1 if you want a simple remote gaming VM
display_width = 1920 # Maximum display width in the VM
display_height = 1080 # Maximum display height in the VM
max_pixels = 2073600 # This is the product of display_width and display_height so 1920 * 1080 = 2073600
cuda_enabled = 1 # Enables CUDA support. Either 1 or 0 for enabled/disabled
frl_enabled = 1 # This controls the frame rate limiter, if you enable it your fps in the VM get locked to 60fps. Either 1 or 0 for enabled/disabled
framebuffer = 0x74000000
framebuffer_reservation = 0xC000000 # In combination with the framebuffer size
# above, these two lines will give you a VM
# with 2GB of VRAM (framebuffer + framebuffer_reservation = VRAM size in bytes).
# See below for some other sizes
[vm.100]
frl_enabled = 0
# You can override all the options from above here too. If you want to add more overrides for a new VM, just copy this block and change the VM ID
```
There are two blocks here, the first being `[profile.nvidia-259]` and the second `[vm.100]`.
The first one applies the overrides to all VM instances of the `nvidia-259` type (thats `GRID RTX6000-4Q`) and the second one applies its overrides only to one specific VM, that one with the proxmox VM ID `100`.
The proxmox VM ID is the same number that you see in the proxmox webinterface, next to the VM name.
You don't have to specify all parameters, only the ones you need/want. There are some more that I didn't mention here, you can find them by going through the source code of the `vgpu_unlock-rs` repo.
For a simple 1080p remote gaming VM I recommend going with something like this
```toml
[profile.nvidia-259] # choose the profile you want here
num_displays = 1
display_width = 1920
display_height = 1080
max_pixels = 2073600
```
### Common VRAM sizes
Here are some common framebuffer sizes that you might want to use:
- 512MB:
```toml
framebuffer = 0x1A000000
framebuffer_reservation = 0x6000000
```
- 1GB:
```toml
framebuffer = 0x38000000
framebuffer_reservation = 0x8000000
```
- 2GB:
```toml
framebuffer = 0x74000000
framebuffer_reservation = 0xC000000
```
- 3GB:
```toml
framebuffer = 0xB0000000
framebuffer_reservation = 0x10000000
```
- 4GB:
```toml
framebuffer = 0xEC000000
framebuffer_reservation = 0x14000000
```
- 5GB:
```toml
framebuffer = 0x128000000
framebuffer_reservation = 0x18000000
```
- 6GB:
```toml
framebuffer = 0x164000000
framebuffer_reservation = 0x1C000000
```
- 8GB:
```toml
framebuffer = 0x1DC000000
framebuffer_reservation = 0x24000000
```
- 10GB:
```toml
framebuffer = 0x254000000
framebuffer_reservation = 0x2C000000
```
- 12GB:
```toml
framebuffer = 0x2CC000000
framebuffer_reservation = 0x34000000
```
- 16GB:
```toml
framebuffer = 0x3BC000000
framebuffer_reservation = 0x44000000
```
- 20GB:
```toml
framebuffer = 0x4AC000000
framebuffer_reservation = 0x54000000
```
- 24GB:
```toml
framebuffer = 0x59C000000
framebuffer_reservation = 0x64000000
```
- 32GB:
```toml
framebuffer = 0x77C000000
framebuffer_reservation = 0x84000000
```
- 48GB:
```toml
framebuffer = 0xB2D200000
framebuffer_reservation = 0xD2E00000
```
`framebuffer` and `framebuffer_reservation` will always equal the VRAM size in bytes when added together.
## Adding a vGPU to a Proxmox VM
Go to the proxmox webinterface, go to your VM, then to `Hardware`, then to `Add` and select `PCI Device`.
You should be able to choose from a list of pci devices. Choose your GPU there, its entry should say `Yes` in the `Mediated Devices` column.
Now you should be able to also select the `MDev Type`. Choose whatever profile you want, if you don't remember which one you want, you can see the list of all available types with `mdevctl types`.
Finish by clicking `Add`, start the VM and install the required drivers. After installing the drivers you can shut the VM down and remove the virtual display adapter by selecting `Display` in the `Hardware` section and selecting `none (none)`. ONLY do that if you have some other way to access the Virtual Machine like Parsec or Remote Desktop because the Proxmox Console won't work anymore.
Enjoy your new vGPU VM :)
## Licensing
Usually a license is required to use vGPU, but luckily the community found several ways around that. Spoofing the vGPU instance to a Quadro GPU used to be very popular, but I don't recommend it anymore. I've also removed the related sections from this guide. If you still want it for whatever reason, you can go back in the commit history to find the instructions on how to use that.
The recommended way to get around the license is to set up your own license server. Follow the instructions [here](https://git.collinwebdesigns.de/oscar.krause/fastapi-dls) (or [here](https://gitea.publichub.eu/oscar.krause/fastapi-dls) if the other link is down).
## PSA for Pascal (and older) GPUs like the P4, GTX 1080...
Starting from driver version 17.0, nvidia in their infinite wisdom dropped support for older cards, so now no matter if the card used to be supported (Tesla P4 etc) or not, you have to patch the driver.
**In addition to that** you have to copy the vgpuConfig.xml from 16.x and replace the new 17.x xml. To do that, you install and patch the 17.x driver as described above, and then extract the 16.x driver with `./driver.run -x`, and copy the `vgpuConfig.xml` from inside the extracted archive to `/usr/share/nvidia/vgpu/vgpuConfig.xml` (replace the existing file). Then reboot and you should see vgpu profiles in mdevctl again.
## Common problems
Most problems can be solved by reading the instructions very carefully. For some very common problems, read here:
- The nvidia driver won't install/load
- If you were using gpu passthrough before, revert **ALL** of the steps you did or start with a fresh proxmox installation. If you run `lspci -knnd 10de:` and see `vfio-pci` under `Kernel driver in use:` then you have to fix that
- Make sure that you are using a supported kernel version (check `uname -a`)
- My OpenGL performance is absolute garbage, what can I do?
- Read [here](#important-notes)
- `mdevctl types` doesn't output anything, how to fix it?
- Make sure that you don't have unlock disabled if you have a consumer gpu ([more information](#have-a-vgpu-supported-card-read-here))
- vGPU doesn't work on my RTX 3080! What to do?
- [Learn to read](#your-rtx-30xx-or-40xx-will-not-work-at-this-point-in-time)
- Make sure that you don't have any dummy plugs connected to the GPU ports, they may cause problems as [reported by a user from the vgpu discord](https://discord.com/channels/829786927829745685/1182258311014400040/1187339682082721822)
## Support
If something isn't working, please create an issue or join the [Discord server](https://discord.gg/5rQsSV3Byq) and ask for help in the `#proxmox-support` channel so that the community can help you.
> ### DO NOT SEND ME A DM, I'M NOT YOUR PERSONAL SUPPORT
When asking for help, please describe your problem in detail instead of just saying "vgpu doesn't work". Usually a rough overview over your system (gpu, mainboard, proxmox version, kernel version, ...) and full output of `dmesg` and/or `journalctl --no-pager -b 0 -u nvidia-vgpu-mgr.service` (<-- this only after starting the VM that causes trouble) is helpful.
Please also provide the output of `uname -a` and `cat /proc/cmdline`
