Actually thinking about it more it would be probably possible for KVM to emulate ArchPerfMon on AMD and Family 15 Intel based on the local PMU. ArchPerfmon has only a few defined counters which can likely be all emulated with other counters. Then the migration would work and PMU also. The only issue is that some clients might check the cpu vendor/model/family in addition to the ArchPerfMon. So to do successfull migration you would always need to fake an ArchPerfMon capable CPU in CPUID initially. So e.g. even if you ran on AMD SVM you would need to fake a Yonah or Core2.o Not sure if that had other bide side effects. Perhaps it could be made optional. -Andi ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
