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

Here is the yum info output for the kernel package on the offending host:
Installed Packages Name : kernel Arch : x86_64 Version : 3.10.0 Release : 327.36.3.el7 Andrea
