About this tag
The vfio tag on WindowsForum.com covers discussions about using VFIO (Virtual Function I/O) for GPU passthrough and device assignment in virtualized environments, particularly with Proxmox and KVM/QEMU. Topics include configuring UEFI firmware, virtual TPM, and VirtIO drivers for Windows 11 VMs, as well as debunking common myths about VM performance and passthrough reliability. The content focuses on practical, step-by-step guidance for hobbyists and home-lab users seeking to achieve near-native hardware performance in virtual machines.

    Install Windows 11 on Proxmox: UEFI, TPM, VirtIO Drivers & GPU Passthrough

    Installing Windows 11 on Proxmox is eminently doable, but it’s not the “select ISO and click next” experience many users expect — you’ll need additional ISOs, a UEFI firmware, a virtual TPM, and the correct VirtIO drivers at the right step in the installer to get a clean, performant VM...
