Did you set global maintenance mode at update time?
If not, ovirt-ha-agent could try to restart the engine VM for HA reasons in
the middle of the update with potentially dangerous results.

Hi,
you can add 'bootOrder:1' and the path to your iso image after 'path:' on
your cdrom device line in a local copy of vm.conf.
You have also to remove 'bootOrder:1' from the disk device.

So you can try starting the VM with
  hosted-engine --vm-start --vm-conf=/your/custom/vm.conf

Good luck
