BZ https://bugzilla.redhat.com/show_bug.cgi?id=1709970

Brew: http://brewweb.devel.redhat.com/brew/taskinfo?taskID=21668672

Branch: rhel-8.1.0

In v1, we included CascadeLake Server cpu model.  That has been removed

in favor a separate submission.

---

Now that kvm_arch_get_supported_cpuid() will only return

arch_capabilities if QEMU is able to initialize the MSR properly,

we know that the feature is safely migratable.
