[ovirt-users] Clarifications regarding ovirt-provider-ovn network

Hi, I had some questions a overt-provider-ovn based external network which is built on top of an physical network. I notice that VLAN tagging gets greyed out when I try to create an external provider network. Is it not supported by overt right now?I am on version 4.2.5.3. Also, if I create NICs with the external provider network built atop a physical network on VMs that are on different hosts, but the same cluster, I see they are unable to ping each other, though it seems to work fine if they are on the same host. Is that elected behaviour? Could you you please help me understand why? Thanks, Anurag
