[builderall]

Hi, can you please see if anything can be done, using ON 5.6 with local zfs (all in one box)

The relevant error seems to be this:

file=/var/lib/one//datastores/0/3/disk.0,format=qcow2,if=none,id=drive-virtio-disk0,cache=none: Image is not in qcow2 format

I don't know (yet) if qcow2 can work but your template surely demanded qcow2 from an image that was not.
