This guide describes how to allocate vGPU resources to a virtual machine (VM), installing the necessary drivers and checking whether the vGPU can be used. Repository access as well as access 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.
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. While finalizing the setup for more vGPU profiles, the only flavor accessible right now is:
- 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 and 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 package dkms is required from the EPEL Repository
[root@centos7]# yum -y install epel-release
Install the Arbutus Cloud repository, it also installs the public key the package are signed with to ensure their authenticity, since these drivers and userspace tools are carefully tested first 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
After the successful installation, the vGPU is a now accessible and licensed.
[root@centos7]# nvidia-smi

Preparation of a VM running CentOS8
Once the VM is available, make sure to update the OS to the latest available software, including the kernel and reboot the VM to have the latest kernel running.
[root@centos8]# dnf -y update && reboot
Since the proprietary nvidia drivers need to be compiled against the running kernel, the package dkms is required from the EPEL Repository
[root@centos8]# dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
Install the Arbutus Cloud repository, it also installs the public key the package are signed with to ensure their authenticity, since these drivers and userspace tools are carefully tested first against the infrastructure, before they are made available.
[root@centos8]# dnf -y install http://repo.arbutus.cloud.computecanada.ca/pulp/repos/centos/arbutus-cloud-vgpu-repo.el8.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@centos8]# dnf -y install nvidia-vgpu-kmod nvidia-vgpu-gridd nvidia-vgpu-tools
After the successful installation, the vGPU is a now accessible and licensed. To check on the status, the same nvidia-smi commands can be used as seen above for Centos7.
Preparation of a VM running Debian10
Ensure that the latest packages are installed and the system has been booted 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 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 of the local apt cache and installation of the vGPU packages.
root@debian10:~# apt-get update && apt-get -y install nvidia-vgpu-kmod nvidia-vgpu-tools nvidia-vgpu-gridd
After the successful installation, the vGPU is a now accessible and licensed. To check on the status, the same nvidia-smi commands can be used as seen above for Centos7.
Preparation of a VM running Ubuntu20
Ensure that the OS is up to date and all the latest patches are installed and the latest stable kernel is running.
root@ubuntu20:~# apt-get update && apt-get -y dist-upgrade && reboot
After a successful reboot, the system should have the latest avaible kernel running and the repository can be installed, by installing the repo package. This package does also contain the gpg key all packages are signed with.
root@ubuntu20:~# wget http://repo.arbutus.cloud.computecanada.ca/pulp/deb/ubuntu/pool/main/arbutus-cloud-repo_0.1ubuntu20_all.deb root@ubuntu20:~# dpkg -i arbutus-cloud-repo_0.1ubuntu20_all.deb
The same warning will be displayed since the signature key is added via post install stage when the package is being installed and can be ignored. Update of the local apt cache and installation of the vGPU packages.
root@ubuntu20:~# apt-get update && apt-get -y install nvidia-vgpu-kmod nvidia-vgpu-tools nvidia-vgpu-gridd
After the successful installation, the vGPU is a now accessible and licensed. To check on the status, the same nvidia-smi commands can be used as seen above for Centos7.
Preparation of a VM running Ubuntu18
Ensure that the OS is up to date and all the latest patches are installed and the latest stable kernel is running.
root@ubuntu18:~# apt-get update && apt-get -y dist-upgrade && reboot
After a successful reboot, the system should have the latest avaible kernel running and the repository can be installed, by installing the repo package. This package does also contain the gpg key all packages are signed with.
root@ubuntu18:~# wget http://repo.arbutus.cloud.computecanada.ca/pulp/deb/ubuntu18/pool/main/arbutus-cloud-repo_0.1ubuntu18_all.deb root@ubuntu18:~# dpkg -i arbutus-cloud-repo_0.1ubuntu18_all.deb
The same warning will be displayed since the signature key is added via post install stage when the package is being installed and can be ignored. Update of the local apt cache and installation of the vGPU packages.
root@ubuntu18:~# apt-get update && apt-get -y install nvidia-vgpu-kmod nvidia-vgpu-tools nvidia-vgpu-gridd
After the successful installation, the vGPU is a now accessible and licensed. To check on the status, the same nvidia-smi commands can be used as seen above for Centos7.
