Description of problem:

Attempt to restore a snapshot on VM with spec including "runStrategy: RerunOnFailure" gets stuck indefinitely.

Version
4.18

How reproducible: 100%

Steps to Reproduce:
1. Take a Snapshot of VM which includes "runStrategy: RerunOnFailure" in the spec.
2. Stop the Vm.
3. Restore the Snapshot.

Actual results:
The Snapshot restore does not complete.

Expected results:
The Snapshot restore should complete.

Additional info:
It appears that virt-controller immediately tries to start the VM after the snapshot restore is triggered. The VM start is denied but this is probably blocking the restore of snapshot. I will be adding the Snapshot details and virt-controller logs to the bug for review.
