: Edit your VM's XML definition with virsh edit <VM-Name> . Find the hostdev section that corresponds to your iGPU and add the <rom file='/path/to/i915ovmf.rom'/> element inside it. It should look like:
echo "0" > /sys/class/drm/card0/gt/gt0/mdev_supported/i915-GVTg_V5_8/create
In many bug reports (e.g., Launchpad #1948372 for Ubuntu 22.04), users report:
Search for HANG and correlate with the last i915ovmfrom upd line.
: For the latest hardware, Intel is introducing the experimental 'xe' driver , which enables features like GuC and HuC firmware by default, moving away from some of the legacy constraints of the i915. 3. Graphics Virtualization: GVT-g vs. SR-IOV
This is the most common problem. The VM starts, but no video output appears on the monitor.
Kernel updates re-generate the /boot/grub/grub.cfg file. If parameters like i915.enable_guc or kvm.ignore_msrs were not appended to the persistent layout correctly, the host re-claims the GPU.
Before you begin, ensure your hardware and software meet the requirements:
