Yes, this is perfectly possible. As of my last patch set we will never
enter the generic emulator for HV KVM, so that race is moot (we just
inject a PROGRAM interrupt into the guest). With this patch even the

don't modprobe kvm-pr.ko.
What is a PROGRAM interrupt? :)
The thing that happens when you invoke an illegal or privileged
instruction ;)
