That may be the case. But what we put in the shared_info page and in the vcpu_info is time keeping information which KVM has done for guests — from the kernel — for a very long time. Again, you could make the argument that some of this stuff *could* be done — albeit less efficiently — form userspace. But again, that ship sailed years ago. -- Sent from my Android device with K-9 Mail. Please excuse my brevity.
