Ok, new issue after the update:
After the reboot of the server none of the VM's were started (including the VM with XO from the sources). I checked this in the status screen with a display connected to the server.
I downloaded the latest daily version of xcp-ng center. Was able to connect to the server but no vm's were started as suspected.
There I saw an error for my ISO repository that resides on my NAS (Samba). Trying to solve it from xcp-ng center did not work (
SM has thrown thrown a generic python exception).
I was able to start the XO vm and from there when trying to reconnect the ISO repository I got this error in the log:
When trying to reconnect from the console:
