I have a Windows 10 LTSC VM (my only VM right now) that appears to stop at random intervals. Sometimes it may stay online for an hour and other times several. I dont know what to make of the logs, but every time this happens I see the same last few lines.

I am having same issue.  Would love to see if any responses. 

First thing is to check that the VM isnt set to sleep or hibernate which is the default setting for any windows install

I'm having the same problem. My windows VM is set to never sleep or hibernate. Its predominately my Steam platform.

 

I've attached the VM log.

 

Once the VM crashed I'm unable to get it to restart without a reboot of the system. The KVM wont release the hardware.
