Hi Callum,

For some reason, when installing the host the management network wasn't attached to the host.

Since the management network is required, due to https://bugzilla.redhat.com/1570388 the host stuck in non operational <-> activating states.

You have two options -

1. Updating ovirt to ovirt-engine-4.2.3.4 and re-installing the host.

2. Trying to understand why the management network wasn't attached to the host at the first place.

If you choose option 2 please attach the full engine logs (engine.log, server.log) and vdsm logs (vdsm.log, supervdsm.log).

Thanks,

Alona.
