HYPERVISOR ERROR, how to solve?

Question

HYPERVISOR ERROR, how to solve?

Anonymous

I have a windows server VM running on a synology host.

It has been running for almost a year but as of a couple of days ago I have been having crashes with the error: HYPERVISOR ERROR. It all happens after I turn on the VM and then wait for circa 20 minutes and it appears. Then the machine reboots and the cycle starts.

This is the screen I receive:

After a couple of runs trying to troubleshoot the issue (unsuccessfuly) I am resorting to asking the question here.

Below are the dump logs I collected from the server.

Hello,

Thank you for posting in Microsoft Community forum.

Based on the description, I understand your question is related to Windows Server VM crash.

I understand you would like to analyze the full system memory dump, but please understand the detailed dump analysis will require more professional resources and this may beyond this forum's range.

But you can still check some available information in Microsoft documents:
