January 3, 20242 yr --RESOLVED Turned out to be a bad VM XML config. Hello I have just installed and set up my 6.12.6 UNRAID server from scratch, created 2 VMs and some dockers and everything seemed to be working well. That is until I leave the server idling for a few hours. At completely random intervals, the UNRAID web ui and display console become unresponsive suggesting the host has crashed. I am not able to ping the server either so the only option I have at this point is to hard reset the host. I have disabled global c-states in the BIOS (intel Z490 mobo) and run a memtest, no issues there. To rule out my hardware, I booted in to windows and ran some stability/stress testing tools on the mem and cpu for about an hour, no problems reported. Please can someone take a look at the logs and help me diagnose the problem? Thank you. diagnostics-20240103-0851.zip syslog-previous-unraid-crash Edited January 8, 20242 yr by mikeyosm RESOLVED
January 5, 20242 yr Author UPDATE - I have narrowed down the freeze/lock-up to only happening when a VM is powered on. My first test was to just leave a bunch of docker containers running and nothing else, the system stayed up for 24hrs+. The second test was to leave a VM powered on and wait until the system crashes. Approximately 1-2hrs later, the host froze. Anything I can do to log the VM/libvirt usage and work out what's causing the crash?
