This sounds like the same problem we're investigating in Fedora/RHEL
land affecting guests with EPYC CPU, or host-passthrough from an EPYC
family 17h host. Workaround should be to use "-cpu Opteron_G5" for now

Looks like windows is tickling an undocumented MSR and we're trying to
find out what this MSR is supposed todo and thus how to handle it in
KVM/QEMU
