I need a quick piece of advice, please.

I'm at setting up the oVirt Engine VM (ie doing a "hosted-engine --deploy") 
stage.

The Host has 3 NICs.

NIC_1 and NIC_2 are bonded (bond1) and run 2 VLANs (on bond1.1 and bond1.2).

VLAN_1 is to be used as the "everyday connection VLAN for the VMs" (including 
the oVirt Engine VM - I think).

VLAN_2 is *only* to be used for data traffic to-and-from our Ceph Cluster (ie 
via the Ceph iSCSI Gateway Nodes).

NIC_3 (running VLAN_3) is to be used for oVirt-host-to-oVirt-host comms 
(including "local" Gluster traffic - yes, the (oVirt) hosts are running a 
couple of Gluster drives).

My question is: Which interface should we use for the "ovirtmgmt" Bridge?

I suspect it should be NIC_3 (VLAN_3), and I'm 99.999% sure it *shouldn't* be 
bond1.2 (VLAN_2), but it might be bond1.1 (VLAN_1), so I thought I'd better get 
peoples' input.

You see, I'm not sure what the purpose of the "ovirtmgmt" bridge is. Is it for 
humans to talk to the oVirt Engine, or is it for the oVirt Engine to talk to 
the VMs (and hosts), or is it for some other purpose, or is it for some 
combination of the these? (I have read the doco on the ovirtmgmt bridge, and 
I'm still somewhat confused.)

So, if someone wouldn't mind getting back to me about this, I'd appreciate it.

Cheers

Dulux-Oz
