[Gary Verhulp (gm0neyl0ve)]

This is not happening correctly in the /etc/init.d/ovirt-guest-agent script

chown ovirtagent:ovirtagent /var/log/ovirt-guest-agent

Running that by hand fixes startup issue.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[wondra (wondra)]

There are multiple inconsistencies, actually. I had to use this cloud-init script to get the guest agent to launch:
packages:
 - ovirt-guest-agent
runcmd:
 - [ ln, -s, /dev/virtio-ports/ovirt-guest-agent.0, /dev/virtio-ports/com.redhat.rhevm.vdsm ]
 - [ chown, ovirtagent, /var/log/ovirt-guest-agent ]
 - [ chown, ovirtagent, /dev/virtio-ports/com.redhat.rhevm.vdsm ]
 - [ service, ovirt-guest-agent, start ]
