[Qemu-devel] [PATCH V2] Resend - Enabling IA32_TSC_ADJUST for Qemu KVM guest VMs

2012-11-26 Thread Will Auld
CPUID.7.0.EBX[1]=1 indicates IA32_TSC_ADJUST MSR 0x3b is supported Basic design is to emulate the MSR by allowing reads and writes to the hypervisor vcpu specific locations to store the value of the emulated MSRs. In this way the IA32_TSC_ADJUST value will be included in all reads to the TSC MSR w
