So far, your assessment is spot on from what we've seen. A migration (if you have live migrate that's even better) should net the same result for QEMU. Some have floated the idea of live migrate within the same host. I don't know if nova out of the box would support such a thing. Thanks!

Our understanding is thus that a soft reboot of the VM is not sufficient but a hard one would be OK. Some quick tests have shown that a suspend/resume of the VM also causes a new process. How are others looking to address this vulnerability ? (I guess the security session will have a few extra people signing up in Vancouver now...)
