Subject: [PATCH] KVM: VMX: Advertize RDTSC exiting to nested guests
Date: Mon, 13 Aug 2012 15:38:22 +0300	[thread overview]
Message-ID: <1344861502-4823-1-git-send-email-avi@redhat.com> (raw)

All processors that support VMX have that feature, and guests (Xen) depend on
it.  As we already implement it, advertize it to the guest.
