Update: Resolved this by renaming /boot/config/plugins/dynamix.plg to dynamix.xxx
Upgraded via the GUI, and on boot up no VMs start. Frustrating as i run my home router on a pfsense VM hosted by unraid.
'virsh list' on the command line just sits there and doesnt list domains. Couldnt find anything significant in the syslog when i went through it.
Decided to roll back to 6.5.3, and now array wont start at all, so im going to be in trouble when the other half comes home!
diag zips attached.
