That's two different things here:
The issue that Espen is reporting is that the hosts have different
frequency and guests that relay on the tsc as a source clock will
notice that post migration. The is indeed a problem that -tdf does
not solve. -tdf only adds compensation for the RTC clock emulation.

It's -rtc-td-hack. -tdf does pit compensation, but since usually kernel
pit is used it does nothing.

So this "hack" will not solve our problem?
