Thanks,
not to worry we are still in a testing phase with ovn.
That worked for one host the other failed with
Job for ovsdb-server.service failed because the control process exited with error code.
See "systemctl status ovsdb-server.service" and "journalctl -xe" for
details.
Traceback (most recent call last):
File "/usr/bin/vdsm-tool", line 219, in main

EnvironmentError: Failed to configure OVN controller.

Thanks,
I can see now from "ovn-sbctl show" on the engine machine that 2
of our hosts haven't deployed ovn
● ovn-controller.service - OVN controller daemon
Loaded: loaded (/usr/lib/systemd/system/ovn-controller.service; disabled; vendor
preset: disabled)
Active: inactive (dead)
This was one of the things that was confusing me
I'll see if I can deploy ovn without reinstalling, also is it possible to change the
deployment to use a different network rather than ovirtmgmt?
You could use vdsm-tool to reconfigure OVN on the hosts.
Please try this:
vdsm-tool ovn-config <your_engine_ip> ovirtmgmt
If you want to setup your overlay on top of a different network,
replace ovirtmgmt with that network name.
To ensure connectivity accross the cluster, make sure all your hosts
are configured to run overlays on top *of the same network*.
Make sure that other network is good to go before; I'd hate for you to
end up worse than you are now, or lose faith on ovn :)

Paul S.

Let me clarify; the network on top of which it sets up the overlay is
defined when the host is added, and is *only* used for inter-host
communication. When within the same host, it simply uses the OVS
bridge.
What (I think) you mean uses the localnet feature of OVN, where the
packets leaving the OVS bridge are forwarded to the external logical
network you configure.
These 2 concepts are unrelated.
