Hmmm, this is becoming difficult ..
I have added into the engine the custom hook and understand how that will
work. The issue is how can a single NIC use two different bridges ?
Example with OVS would be that one requires:
em1 -+ ovirtmgmt (bridge) -> management IP (public)
+ ovs (bridge) -> firewall IP (public)
|
+ vlan 1
+ vlan 2
this works fine when using OVS and KVM, without oVirt, so there must be a way
to hook the two together without a Neutron appliance.
Any thoughts ? Thanks, Phil.
I haven't tried this, and it may not work, but what happens if you add the ovirtmgmt
bridge as a port of the ovs bridge?

Once you start to use the vdsm-hook-extnet, all that you need to do is
to replace the libvirt-side definition of the "external network". This
may well be an OpenVSwitch-based network e.g.
