Hello all, I'm facing a strange error. I was able to add a host to a linux bridge based cluster. However if I try adding the host to a cluster with OVS switch it is failing. I can see that nmstate was able to create the ovirtmgmt bridge as well. At that point of time both the ovirtmgmt and the bond0.vlan interfaces have the ip assigned. It then fails and rolls back the config. A workaround that I found to be working was to add the host to linux bridge cluster first and then change the cluster to OVS cluster. Here's a background about the setup. The host is an AMD EPYC with OEL 8.6 installed. The OLVM manager is a standalone VM at 4.4.8. We have a bond0 and ip is assigned to bond0.1222 interface. The interfaces are in a LACP bond on the switch as well. I enabled debug in NetworkManager in the hope of finding some clues, but couldn't. I know 4.4 is EOL. As this is a user mailing list, I thought I'll reach out in hope if someone has seen any similar issue. supervdsm log MainProcess|jsonrpc/3::DEBUG::2022-05-26
