Windows 10 Build 1903 Guest OS on 2012 Hyper-V Host is freezing

Question

I created a Guest machine windows 10 Build 1903 on 2012 R2 Host Hyper-V. It works ok at the beginning and then becomes unresponsive. I can't remote, From the host server, client windows shows black screen. I have to foree shutdown the guest to make it work again. No blue screen. Tried removing hyper-v features, updating the server to the latest patches, nothing helped. I don't have the same problem with 1809 Builds.

Thank you in advance.

Answer 1

As a temporary workaround, executing Restart-Service 'HV Host Service' in a PowerShell Admin prompt seems to be making the VMs responsive again.
