How to enable Proxmox GPU passthrough Ubuntu

Proxmox can be described as a popular open-source virtualization platform. It allows users to run virtual machines as well as containers on a single host. With Proxmox, we can use a dedicated graphics card, or GPU, for a VM, also known as GPU passthrough. This comes in handy for applications that need high-performance graphics, like gaming, machine learning, 3D modeling, and so on.

How to enable Proxmox GPU passthrough Ubuntu

According to our experts, using a GPU passthrough enables a virtual machine to enjoy all the benefits offered by a dedicated graphics card, rather than relying on the emulated graphics offered by the virtualization software.

Today, we are going to take a quick look at how to enable GPU passthrough in Proxmox for an Ubuntu VM:

1. To begin with, we have to make sure that our hardware is compatible with GPU passthrough. This involves a CPU and motherboard that supports Intel VT-d or AMD-Vi, Additionally , we require a dedicated GPU that supports IOMMU virtualization.
2. Next, we have to enable IOMMU in the server’s BIOS settings.
3. After that, we must install the required drivers and software on the host system. This includes the vfio-pci kernel module as well as the QEMU virtualization software.
4. Then, configure the VM to use the passthrough GPU. This is done via the Proxmox web interface or by editing the VM’s configuration file.
5. At this point, we have to install the required GPU drivers and software within the Ubuntu guest VM.

After the above steps, the Ubuntu VM will be able to access the passthrough GPU directly, and offer high-performance graphics capabilities.

OUr experts would like to point out that the GPU passthrough is a complex and risky process. Hence, we have to ensure the hardware and software are compatible before attempting GPU passthrough.
