Interest in FOSS virtualization platforms like Proxmox VE and XCP-ng has grown amid Broadcom's acquisition of VMware. Users are exploring passing GPUs to VMs for local AI workloads.
Limitations exist, such as one GPU per VM in PCIe passthrough. Nvidia offers vGPU support on Proxmox but requires a license; XCP-ng supports PCIe passthrough, not vGPU.
Focus is on Linux guests, but works for other OS. Guide details enabling PCIe passthrough on XCP-ng 8.2 and Proxmox VE 8.2 with Nvidia or AMD graphics cards.
XCP-ng facilitates PCI passthrough of GPUs and prevents automatic assignment to the management VM. Proxmox and XCP-ng instructions are highlighted in the tutorial.
