About this tag
The OVMF (Open Virtual Machine Firmware) tag on WindowsForum.com covers discussions about UEFI firmware used in virtualized environments, particularly with KVM/QEMU and Proxmox. Topics include installing Windows 11 on Proxmox VMs, where OVMF provides UEFI support alongside virtual TPM and VirtIO drivers. The tag also addresses security vulnerabilities in EDK II, the open-source UEFI framework underlying OVMF, such as CVE-2024-38796, an integer overflow in PeCoffLoaderRelocateImage. This vulnerability affects Azure Linux and potentially other Microsoft products using EDK II. Discussions focus on patching, attestation, and the broader implications for firmware security in virtualized and cloud environments.

    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...
