Thanks. That did the trick. Nice for a newbie to have someone who
remembers "the old days".


That might not have been the best of wordings on my part. We were still using 3.1 just a couple of months ago:) And I know there are plenty of people still using it. Upgrading was a real PITA, so I fully understand why. Glad it helped!



In betwen I tried to convert the disk back
to virtio but that resulted in a similar issue:

"unsupported configuration: virtio only support device address type 'PCI'."

De- and reattaching the disks will be fine for me for me. Maybe it
would be helpful to disable this change option in the web interface
for attached disks.
