Maybe the last upgrade a few months ago did this...
I suppose the auto start procedure will be the same in this version.
do you actually have a HA serverpool? Afaik, guest autostart is only available when having one. It's true, that will also simply put the guest references in that place, but at least OVMM would manage them. If you don't have a HA serverpool, you'd have to put these references there manually - and manage them manually as well.
Thanks for the reply. Unfortunately no HA. Previously to the upgrade I've created successfully symbolic links in /etc/xen/auto and worked perfectly. I guess I'll have to redo the links. Curious how the upgrade messed with them, though...
