I did see it, but I don't understand. I think you're saying that when
the system hibernates that the hypervisor will take care of KVMs,
so they don't need to do anything (except catch up when they
wake up). A resume= is not needed for VMs.

That is correct. KVM/libvirt will handle saving the VM state before the host shuts off. Then on resume, it restores the VM state and resumes it.
