Hmm, I planned to do the VMSTATE thing in a follow-on patch-set. The plan is to read the VCPU tsc_freq at guest start time on !tsc-scale hosts and migrate it over so that the destination host can set the tsc-freq if it supports tsc-scaling.This can be done by a management tool if desired.
Although, if we do this unconditionally (that is, also for tsc-scale hosts) then we get stable tsc even without supplying a tsc frequency argument... need to think about this.
