@fx991 the SR scans can and have been helpful in detecting storage issues for me. Sometimes when my ISO library goes offline but XCP-ng has not detected the failure and still shows it as connected I usually notice it from the long running SR scans that get stuck.

The "Connection to VM console..." task is when you have a console window open to a VM or Host...hence the reason why you can't cancel/end it...if you want to get rid of it then close all open console windows
