This guide describes how to allocate GPU resources to a virtual machine (VM), installing the necessary drivers and checking whether the GPU can be used.
* install the necessary drivers and  
* check whether the vGPU can be used.
Access to repositories as well as to the vGPUs is currently only available within [https://arbutus.cloud.computecanada.ca Arbutus Cloud]. Please note that the documentation below only covers the vGPU driver installation. The [https://developer.nvidia.com/cuda-toolkit-archive CUDA toolkit] is not pre-installed but you can install it directly from  NVIDIA or load it from [[Accessing_CVMFS|the CVMFS software stack]].
If you choose to install the toolkit directly from NVIDIA, please ensure that the vGPU driver is not overwritten with the one from the CUDA package.

== Preparation of a VM running AlmaLinux 9 ==  
== Preparing a Debian 10 instance == <!--T:5-->


Once the VM is available, make sure to update the OS to the latest available software, including the kernel.
<!--T:24-->
Then, reboot the VM to have the latest kernel running.
To use the GPU via the PCI bus, the proprietary NVIDIA drivers are required. Due to Debian's policy, the drivers are available from the non-free pool only.


To have access to the [https://en.wikipedia.org/wiki/Dynamic_Kernel_Module_Support DKMS package], the [https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm EPEL repository] is required.
===== Enable the non-free pool ===== <!--T:6-->


AlmaLinux 9 has by default a faulty <code>nouveau</code> driver which crashes the kernel as soon as the <code>nvidia</code> driver is mounted.  
<!--T:25-->
The VM needs a few extra steps to prevent the loading of the nouveau driver when the system boots.
Log in using ssh and add the lines below to ''/etc/apt/sources.list'', if they are not already there.

After the reboot of the VM, the Arbutus vGPU Cloud repository needs to be installed.
===== Install the NVIDIA driver ===== <!--T:8-->

<!--T:26-->
<pre>
The following command:
[root@almalinux9]# dnf install http://repo.arbutus.cloud.computecanada.ca/pulp/repos/alma9/Packages/a/arbutus-cloud-vgpu-repo-1.0-1.el9.noarch.rpm</pre>
* updates the <code>apt</code> cache, so that <code>apt</code> will be aware of the new software pool sections,
<translate>
* updates the OS to the latest software versions, and
* installs kernel headers, an NVIDIA driver, and <code>pciutils</code>, which will be required to list the devices connected to the PCI bus.


The next step is to install the vGPU packages, which will install the required driver and user-space tools.

<pre>
[root@almalinux9]# dnf -y install nvidia-vgpu-gridd.x86_64 nvidia-vgpu-tools.x86_64 nvidia-vgpu-kmod.x86_64
root@gpu2:~# apt-get update && apt-get -y dist-upgrade && apt-get -y install pciutils linux-headers-`uname -r` linux-headers-amd64 nvidia-driver
</pre>
</pre>
<translate>


After a successful  installation, <code>nvidia-smi</code> can be used to verify the proper functionality.
<!--T:27-->
If this command finishes successfully, the NVIDIA driver will have been compiled and loaded.

* Check if the GPU is exposed on the PCI bus

== Preparation of a VM running Debian 11 ==
Ensure that the latest packages are installed and the system has been booted with the latest stable kernel, as <b>DKMS</b> will request the latest one available from the Debian repositories.


</translate>
<!--T:16-->
<pre>
To compile the module sources from the NVIDIA repository, it is necessary to install <code>dkms</code>.
root@debian11:~# apt-get update && apt-get -y dist-upgrade && reboot
This will automatically build the modules on kernel updates, and therefore ensures that the GPU is still working after any update of the OS.
</pre>
<code>dkms</code> is provided in the EPEL repository.
<translate>
Kernel headers and the kernel source need to be installed before the NVIDIA driver can be set up.


After a successful reboot, the system should have the latest available kernel running and the repository can be installed, by installing the <code>arbutus-cloud-repo</code> package.
