So it's still true that the time advances during live migration brownout; 0.1 seconds is just the final part of the live migration process. But for _live_ migration there is no need to design things according to "people are happy if their clock is off by 0.1 seconds only".
Agree. What would be a good way to fix this?
None of what's proposed is fixing the underlying problem of wreckaging CLOCK_REALTIME.
Stop proliferating broken behaviour and please answer the questions I asked several times now:
1) Why has the TSC has to restart at the same value?
2) What is the technical argument that it is correct and acceptable to wreckage CLOCK_REALTIME by doing #1?
