I'm not sure what kind of help I can give here, but let me see. > Adrian - can you later please wikify this recurring question? > If this is related to libvirt detecting the wrong CPU, we have a short wiki page  for that either, you can link to that in yours (or maybe it'll help you write it).

Could you try running 'virsh -r capabilities' on the host to check what libvirt reports? There might be a possible workaround if you want your CPU to be identified as different model, most probably by editing '/usr/share/libvirt/cpu_map.xml', but that should be omitted since it may lead to problems.

Check , maybe some features can get enabled.
