Windows Server Technical Preview Hyper-V Missing VM's

I recently upgraded my Hyper-V Host to Windows Server Technical Preview from Windows Server 2012 R2 and noticed that my VM's were missing.  They were still active just not visible in the console.  If you are experiencing the same behavior you can run the following command to make your VM's display in the console again.

(Get-VM).Where({$PSItem.Heartbeat -eq 'OKApplicationsUnknown';}) | Disable-VMIntegrationService Heartbeat

    Thanks, worked for me, but what exactly happened and what does this command do to restore them?

  2. Hi Richard this is a powershell command so open the powershell console and paste in the code above.

    Thank you, I was looking for a solution since yesterday but couldn’t find the answer (no xml corruption, rights on symbolic link were ok). This solved it!

    Thanks! i was constantly restarting my PC on this issue. Though restarting fixes it, but it’s annoying.
