Hi,
Is there some way to start a KVM-accelerated VM with QEMU (on an Intel/VMX
host) that is configured so that RDTSC/RDTSCP instructions won't cause a
VM-exit?
According to Intel's manual, it seems I should disable the "RDTSC exiting"
bit on the MSR that Linux identifies as MSR_IA32_VMX_PROCBASE

Right now, function trace_event_set_vcpu_state_dynamic() asynchronously enables
events in the case a vCPU is executing TCG code. If the vCPU is being created
this makes some events like "guest_cpu_enter" to not be traced.
