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.
