Which required a bit more work, and as I had to rebuild and reinstall windows I used the secure boot OVMF and with that I should be if I decide to 100% windows 11 compliant.  You will need to install swtpm and might have to correct some permissions based on your install, and what user and it's permissions that are running your qemu and libvirt.
