I'd suppose a system_reset should bring the system back to sanity and
then clear vm_permanent_stopped (where's -ly?) except maybe for KVM
internal error if that can't be recovered. Then it would not very
permanent anymore, so the name would need adjusting.

Currently, all kvm internal errors are recoverable by reset (and possibly by fiddling with memory/registers).
