I have created a separate network for 10G network and made central server part of it. After that configured the OVN controller using vdsm-tool
vdsm-tool ovn-config <OVN central server IP> <local IP used for OVN tunneling> Then added OVN provider to oVirt as an external network provider and created a new network based on OVS. Now the new VM's we create use this new network. Thanks for your help!
