Windows 2012 R2 Hyper-V Server Ramadomly Rebooting

[DonallyB]

Hi all,

I have a Windows 2012 R2 Hyper-V server in a remote site that we manage that hosts 3 VM's on it.

In the last few days it has started to randomly reboot, it could do this from 4 -7 time a day, each time coming back with the error Event 41, Kernal-Power

"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

My first thought was a loss of power in the rack over in this site, however I checked with our Network team for the uptime of the firewall, switches over there and they haven’t been affected

Without being able to go on-site and check the hardware myself, I have done the usually remotely checks just in case:

• Ensure system firmware bios is up-to-date
• Windows updates are up to date
• Removed 3^rd party software

Have used the hardware vendors diagnostics to run check to see if there are any faulty H/W wtc

We have no It personnel on site that could assist with the troubleshooting so this have been all done remotely

Digging a bit deeper I found that the server had a bugcheck error on the 4^th of Jan this year, and doing so created a memory.dmp file.

I have the detail of the memory.dmp file below which relates to Hypervisor error, however the troubleshooting that I have done so far haven’t turned up anything of note:

Any help with this would be greatly appreciated
