Marcin,
I installed the OVN-Central on a dedicated VM that lives on the ovirtmgmt
network, I also installed the OVN-Provider on this same instance. I then
installed the OVN-Controllers on all 3 of my oVirt Nodes, with the OVN
provider driver, and configured the vdsm ovn-controller {central-ip}
{ovirt-node-ip} on each of the boxes. It appears to be running but what I
am noticing is that the ovs-vswitchd process is pegged at 100% on all the
oVirt nodes.
So for instance from oVirt Node 3 (IP 75) the ovs-vsctl shows the IPs for
the other 2 nodes in it's configuration. It seems to be that way across all
3 nodes, they know about the other nodes in the cluster. I was able to
create a network inside of oVIRT using the external provider. After i
create a subnet inside oVirt I do get an error at the top but seems to be
ok?

One other thing that I notice is that when I got to Provision a Virtual
Machine from the Main Data Center, my Networks don't show under the NIC
where I could select them? Am I missing something on this?
Thanks very much for your help.

Please note the difference between OVN-Central and OVN-Controller:
OVN-Central is the central part of OVN, storing the logical configuration
and controlling the many OVN-Controllers
OVN-Controller is the piece of software which resides on the ovirt-hosts,
and manages the local OVS setup on the host.
OVN-Central
/ | \
/ | \
/ | \
/ | \
OVN-Controller OVN-Controller OVN-Controller
OVN-central can be installed anywhere , as long as it can communicate with
the engine and all the hosts.
During development we install it along the ovirt engine for convinience.
OVN-Controller must be installed on every ovirt host.

Short answer: Yes
Longe answer: If you plan not to use external networks on some clusters,
you
can skip its hosts.
You can choose the clusters which support the external network by
assigning the
network to clusters.

For now it is only the url of the provider.
The provider is still under development, authentication is still just an
empty mock.

We are using the default 'br-int' bridge which OVN is using. All should be
configured
when OVS/OVN is installed.
Let me know if I can help with anything else.
