virtio-win: https://access.redhat.com/downloads/content/70/ver=/rhel---8.4/8.4/x86_64/packages

to fake your cpu to pass win11 checks:

virsh edit windows10

  <cpu mode="custom" match="exact" check="none">
    <model fallback="forbid">Skylake-Server</model>
  </cpu>

this doesn't work for me, but should according to libvirt (version?):

  --cpu model=Skylake-Server,mode=custom,match=exact,fallback=forbid,check=none \
