Ah - interesting. I could recreate the situation on z15 / L1III:
$ virsh start bionic --console Domain 'bionic' started Connected to domain 'bionic' Escape character is ^] (Ctrl + ]) ubuntu@z15test:~$
There is obviously a difference in the behavior of the z13 and z15.
I can create a test kernel with the mentioned patch reverted...
