Hi

We have one Hyper-V core server with a issue when it reboots: VM is missing.

In the event viewer, there is 2 errors:

  • Microsoft-Windows-Hyper-V-VMMS, EventID 22052
  • Microsoft-Windows-Hyper-V-VMMS, EventID 16300

With a simple "Restart-Service vmms", VM is back...

???

    Hi,
    Try to set the Hyper-V VMMS start up type to “Automatic (delayed start)” and check again.
    Please turn off or uninstall any third-party AV tools on your host.

    Best Regards,

    Hi

    We have setup delayed start for the service and it seems to do the trick.

    But still, this is a bit weird on a fresh hyper-v core 2019 installation...

    Thanks for you help !

    Regards
