Package: ovirt-guest-agent Version: 1.0.13.dfsg-2 ovirt-guest-agent 1.0.12.2.dfsg-2 doesn't work with oVirt 4.2 due to changed paths. But when one upgrades to 1.0.13.dfsg-2, the agent still doesn't start and it's necessary to reboot the system or to trigger the necessary changes manually:
udevadm trigger --subsystem-match="virtio-ports" systemctl restart ovirt-guest-agent.service I guess it's because the line udevadm trigger --subsystem-match="virtio-ports" --attr-match="name=com.redhat.rhevm.vdsm" in postinst script still refers to the old “rhevm” name.
