Ok i figured out my issue, the network wasn't configured under the Cluster section to be allowed to see, I have now been able to spin up my own network/subnet and then spin up 2 instances both getting DHCP addresses and able to talk to each other. The ONLY issue i'm seeing is that random UI error that i have e-mailed over to Alexander about. I'll let you know if i have any other questions. I think for now I'm golden.

Marcin,

So an update on my situation, I restarted all OpenVSwitch processes on all boxes and was able to get the CPU issue with ovs-vswitchd to return to normal. So I believe all those issues are resolved. I can create networks/subnets, minus that one strange UI issue which I'll work with Alexander Wels to resolve. When I still go to launch a Virtual Machine, should I be seeing the subnets that I created? Am I missing something? It seems like i'm about 95% there and I am just missing something.

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.
