With the support of S4 sleep state (hibernate) for HVM guests, we now have a situation where the guest is resuming from hibernate while the hypervisor assumes that it is spinning up a new guest VM. And so, if the hypervisor maintains any guest specific state that needs to persist across a hibernate, there is no way to save and restore this state. I am running into this problem on win2k8 guests where the Hyperv shim has to maintain guest specific state that needs to persist across a hibernate.
Given that we already support save/restore which is functionally equivalent to hibernate, do we need to support S4 sleep state?
