June 14, 20251 yr I found my Windows VM in my Unraid server non-functional today. The VM Console VNC showed the VM had failed to boot, and was at the blue repair screen.I tried the repair option, and it started to boot, but then the host Unraid OS restarted. After I was able to log in to the Unraid web interface, I looked at the log http://t440.local/webterminal/syslog/ to see what happened.I didn't see anything that was helpful in diagnosing they cause of the restart.The Windows VM Console VNC again showed the VM had failed to boot, and was at the blue repair screen.This time instead of repair, I selected Advanced, and boot Windows 11 normally. It booted and displayed a notification that a windows update was removed. In the Windows System Log I found Installation Failure: Windows failed to install the following update with error 0x800F0845: 2025-06 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5060842).Has anyone else had issues with a Windows update failing and crashing the VM and Unraid? Any suggestions on preventing this in the future?
