[libvirt] [PATCH 0/5] Fix hyperv and kvm features with QEMU 4.1

Originally the names of the hyperv and kvm CPU features were only used
internally for looking up their CPUID bits. But with QEMU 4.1 we check
which features were enabled or disabled by a freshly started QEMU
process using their names rather than their CPUID bits (mostly because
of MSR features). Thus we need to change our made up internal names into
the actual names used by QEMU.

Otherwise libvirt would mistakenly report the features as unavailable
and refuse to start any domain using them with QEMU 4.1.
