I found the bug got fixed in kvm upstream. Gleb, you fixed it by the following commit? commit 7f85a520ba8407af6384aac32d829988ab543ebf Author: Gleb Natapov <gleb@xxxxxxxxxx> Date: Sun Jan 15 14:17:22 2012 +0200 KVM: do not #GP on perf MSR writes when vPMU is disabled Return to behaviour perf MSR had before introducing vPMU in case vPMU is disabled. Some guests access those registers unconditionally and do not expect it to fail. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
