with hv-frequencies, allows Hyper-V on KVM to pass stable clocksource (Reference
TSC page) to its own guests.
Note, KVM doesn't fully support re-enlightenment notifications and doesn't
emulate TSC accesses after migration so 'tsc-frequency=' CPU option also has to
be specified to make migration succeed. The destination host has to either have
the same TSC frequency or support TSC scaling CPU feature.
