Hyper-V guest will not restart unless manager service is running on host

Have a number of 2008 and 2012 VMs running on a 2012 Hyper-V host.

If I restart any VM from within the guest OS, it will only restart if the HV manager service is currently running on the host.

So if the service is not running (i.e. most of the time) when a VM restarts due to eg. windows updates, it will not start up until someone logs in to the host and starts the manager service.

How can I set it up so that the VMs restart automatically?

There are there "management" services. The I age manager, the network manager, and the virtual machine manager. And all three should be in a running state all the time. If you are finding them in a stopped state then that is your problem. Find put why the service is stopping/crashing. Event logs, scheduled tasks, conflicts, permissions, etc.

Ah, I assumed that the management service(s) was shutting down to save resources and this was something that happened by default as it has always done this.

So obviously that's where the issue is as you say.

Found the culprit.  An apprentice was clicking Stop Service each time they closed Hyper-V Manager as they thought this is what needed to be done.

Operator error.
