Hi
I am getting some problems setting up an internal networks for our oVirt VMs using the
OVN external provider.
The ovn-provider was setup during the ovirt engine installation (version 4.3.7.2-1.el7).
I then just created a new network with the ovn external provider and tested the
connectivity using the corresponding button on the oVirt UI. Two of my VMs are Ubuntu
18.04 servers with ips 10.0.0.101 and 10.0.0.102 with gateways 10.0.0.102 and 10.0.0.101
respectively. So I guess under normal circumstances they should be able to ping each
other.
I tried disabling the firewalld service on both the host and the ovirtengine but still
nothing changed. However I noticed something odd on the firewalld status on the host. With
firewalld enabled, I get:
[root@ovirt7 ~]# systemctl status firewalld

On the ovirt engine I have:

so I guess tunneling is correctly setup right. On the host I am seeing:

I have not found anything useful in the log files.
Does anyone have any thoughts?
Thanks!
