`Rocky-8-GenericCloud-8.6-20220515.x86_64.qcow2`: `cloud-init` failing

[waldner]

On a stock Rocky-8-GenericCloud-8.6-20220515.x86_64.qcow2 image, imported into Openstack and booted, cloud-init fails due to missing hostname and service commands. Here the relevant log snippets:

2022-05-30 16:21:31,521 - util.py[DEBUG]: Failed to update the hostname to testinstance.novalocal (testinstance)

The above exception was the direct cause of the following exception:

So the result is:

Ah thanks, I didn't think of looking there. Closing this one then.
