Here are the top line facts:
I have found other qemu posts (not proxmox) where this host passtrough on win11 seems to cause issues.
Things i have tried:
I need a way to keep host CPU enabled and avoid the reboot loops.
OR
I need a way with a virtualized CPU type to not have the windows intel drivers fail
I realize not everyone has this issue so i wonder if it is something to do with the specifics of my cpu?
- I have i915 vGPU working on my host.
- I install a new win11 VM.
- I get the win11 VM working with VGPU
- at some point later on a reboot the Win11 machine goes into automatic repair (this seems to be time based, not due to windows updates, not installing anything, not changing anything
- if i set the CPU type to x86-64-v2-AES then the system boots...
- ...but this breaks vGPU with the dreaded code 43

Things i have tried:
- setting /sys/module/kvm/parameters/ignore_msrs = Y
- setting host,hidden=1
- tried this driver trick - works to get access to c:\ but no improvement
- various args in the vm conf
- re-installing win11 in fresh VM multiple times
- disabling network to stop updates
