You've probably thought it through and I didn't but wouldn't it be
easier to have one global pm_notifier call for KVM which would go
through the list of VMs instead of registering/deregistering a
pm_notifier call for every created/destroyed VM?

That raises questions on the locking, i.e. if we can we take the kvm_lock
safely from the notifier.

Right, I wanted to take the VM lock, rather than subsystem lock
(kvm_lock).
