> When a host is detected as Down, HA-enabled VMs running on it are scheduled for restart.
There may be scenarios where both user VM and corresponding VR is on the same host and scheduled
for restart. In such cases user VM restart will fail in initial attempts until VR is restarted.
One way to reduce these occurrences is to schedule VR restart ahead of user VMs.
