Would that be a problem, though? Sounds like an "improvement" to me. :-) I mean, if we keep using the same TSC across all vCPUs, the guest will actually see a single TSC and thus have stable and synchronized TSCs. Unlike the host. I.e., the guest will be better than the host! :-) -- Regards/Gruss, Boris. SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) --
