I'd first like to understand how you intend for management traffic to
travel from your Engine to the host. Do you have a vlan connection
between the two? What is the host's IP address on that vlan?

Since you have connectivity to the host, we can tell that you have
un-tagged traffic to the host. In most (sane) cases, the IP address on
the untagged network is different from the vlan'ed one. To use the
latter, you'd need to remove the host from the cluster, and add it back
with its second address.

Did you define ovirtmgmt as a vlan-tagged network? Or do you intend to
have a special hack for this host?
