[ovirt-users] Communicate between the guest vm's hosted on different hosts on different data centres using OVS

Hello, I have configured OVS network on oVirt 4.1.1, following the document https://www.ovirt.org/blog/2016/11/ovirt-provider-ovn/ I have created OVN Provider, and created new Logical Network for OVS using OVN Provider. I have synced the network also selected OVS when I created the cluster. I have two data centres and each data centre has one host each. Now I have created VM's selecting OVS network (not ovirtmgmt). VM's in the same data centre can talk to each other. How do i make the VM's hosted on different data centre can talk to each other? Appreciate your help in advance, Sincerely, Suresh.
