This sounds like a result of the network not being in sync. 
Currently, the host is installed with a "VM" management network automatically (there is work to change that) 
If the network is defined as "non VM" on the data center level, you will still see it as a VM network in the "setup networks" command on the host.

This is because it's "unsynchronized".

You need to select the "synchronize this network" checkbox in the "edit" dialog which you see the boot protocol on, it's at the bottom of the dialog.

Indeed, except the possible bug in the error that states "<UNKNOWN>", once you will synchronize the network this all will not be happening.
