Libvirt Service failed to start

[bobokun]

I noticed that in VMs tab I see a Libvirt Service failed to start. message, however my VM is still running and I can access it. Even when going to systems VM Manager and disable VMs, it doesn't shut down my VM and I still see it running. It has been working fine for many years, the only change I've done recently was upgrade to 6.9.1 and also replaced the data with a new cache pool (moved all files from previous cache onto the new cache pool).

 

Please see diagnostics attached.

Try rebooting.

Rebooting did fix it however it caused an unclean shutdown, so now it's performing a parity check. Could you find any reason in the logs as to why this happened? Do you know if this will be recurring?

Unclean shutdown saves the diags in the flash drive (logs folder), they might give a clue for the reason.

Mar 23 10:33:20 unNAS emhttpd: shcmd (1726): umount /mnt/cache
Mar 23 10:33:20 unNAS root: umount: /mnt/cache: target is busy.

 

Something was still using /mnt/cache, it failed to unmount without forcing.

Thanks. I have a feeling the vm probably didn't shut down properly during that time and was using cache. Either way thanks for the input. Hopefully this solves the issue
