[ovirt-users] OVN Provider setup issues

[Andrea Fagiani]

Hi all,

I've been messing around with the ovirt-ovn-provider [1] and I've run 
into some issues during the initial setup.

I have a 5-node cluster (running the hosted-engine VA), LEGACY virtual 
switch; this test was done on a single host. Following the instructions 
from the aforementioned blog post, I have downloaded the 
ovirt-provider-ovn and ovirt-provider-ovn-driver rpms, and built the rpm 
packages for:

- openvswitch (2.6.90)
- openvswitch-ovn-common
- openvswitch-ovn-host
- openvswitch-ovn-central
- python-openvswitch

I set up a dedicated VM for the OVN controller, installed ovs and 
ovn-central, started the ovn-northd and ovirt-provider-ovn services. So 
far so good. I then moved on to the oVirt host and installed the above 
packages (minus ovn-central) as well as the ovirt-provider-ovn-driver 
provided, started the ovn-controller service and ran

# vdsm-tool ovn-config <ovn controller IP> <host management IP>

Executing the suggested checks I noticed that something didn't quite go 
as planned. Below is the /var/log/openvswitch/ovn-controller.log from 
the host machine. There are no firewalls involved (not even on the 
servers) and I also tried disabling SELinux but to no avail.

Any ideas?

Thanks,
Andrea
