This is not a complete article: This is a draft, a work in progress that is intended to be published into an article, which may or may not be ready for inclusion in the main wiki. It should not necessarily be considered factual or authoritative.
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.
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.
- vgpu1-c18-56gb
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 https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.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@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.
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.
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.
