Using cloud vGPUs
This guide describes how to
- allocate virtual GPU (vGPU) resources to a virtual machine (VM),
- 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 Arbutus Cloud. Please note that the documentation below only covers the vGPU driver installation; the CUDA toolkit is not pre-installed. The CUDA toolkit can be installed directly from Nvidia or used from 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.
Supported flavors
To use a vGPU within a VM, the instance needs to be deployed on one of the flavors listed below. The vGPU will be available to the operating system via the PCI bus.
- g1-8gb-c4-22gb
Preparation of a VM running CentOS7
Once the VM is available, make sure to update the OS to the latest available software, including the kernel. Then reboot the VM to have the latest kernel running.
[root@centos7]# yum -y update && reboot
Since the proprietary Nvidia drivers need to be compiled against the running kernel, the dkms package is required from the EPEL Repository
[root@centos7]# yum -y install epel-release
Install the Arbutus Cloud repository. This also installs the public key the packages are signed with to ensure their authenticity. These drivers and user-space tools are carefully tested against the infrastructure before they are made available.
[root@centos7]# yum -y install http://repo.arbutus.cloud.computecanada.ca/pulp/repos/centos/arbutus-cloud-vgpu-repo.el7.noarch.rpm
The last step is to install the nvidia vGPU packages.
The kernel module package nvidia-vgpu-kmod will take a few minutes as it compiles the required kernel modules in the background.
[root@centos7]# yum -y install nvidia-vgpu-kmod nvidia-vgpu-gridd nvidia-vgpu-tools
If your installation was successful, the vGPU will be accessible and licensed.
Test by running nvidia-smi:
[root@centos7]# nvidia-smi

Preparation of a VM running Debian10
Ensure that the latest packages are installed and the system has been booted with the latest stable kernel, as dkms will request the latest one available from the Debian repositories.
root@debian10:~# apt-get update && apt-get -y dist-upgrade && reboot
After a successful reboot, the system should have the latest available kernel running and the repository can be installed, by installing the arbutus-cloud-repo package.
This package also contains the gpg key all packages are signed with.
root@debian10:~# apt-get -y install gnupg root@debian10:~# wget http://repo.arbutus.cloud.computecanada.ca/pulp/deb/debian/pool/main/arbutus-cloud-repo_0.1_all.deb root@debian10:~# dpkg -i arbutus-cloud-repo_0.1_all.deb
The installation of the package will display a warning, since the key is directly imported (for convenience) via the package's post-installation procedure.
Setting up arbutus-cloud-repo (0.1) ... Warning: apt-key should not be used in scripts (called from postinst maintainerscript of the package arbutus-cloud-repo) OK
Update the local apt cache and install the vGPU packages:
root@debian10:~# apt-get update && apt-get -y install nvidia-vgpu-kmod nvidia-vgpu-tools nvidia-vgpu-gridd
If your installation was successful, the vGPU will be accessible and licensed.
Test by running nvidia-smi as shown above for CentOS7.
