ACK again, although now I noticed the following part of the cover letter would
fit nicely into this commit message...
QEMU supports a bunch of CPUID features that are tied to the kvm CPUID
nodes rather than the processor's. They are "kvmclock", "kvm_nopiodelay",
"kvm_mmu", "kvm_asyncpf". These are not known to libvirt and their
CPUID leaf might move if (for example) the Hyper-V extensions are enabled.
Hence their handling would anyway require some special-casing.
However, among these the most useful is kvmclock; an additional
"property" of this feature is that a <timer> element is a better model
than a CPUID feature.
