I tested oVirt (4.3? I can't remember) last fall on a single host (hyperconverged).
Now, I'm getting ready to deploy to a 3 physical node (possibly 4) hyperconverged cluster, and I guess I'll go ahead and go with 4.4. Although Red Hat's recent shift of CentOS 8 to the Stream model, as well as the announcement that RHV is going away makes me nervous. I really don't see any other virtualization software doing quite the same stuff as oVirt at the moment. One of my questions is around the back end out-of-band network for data replication. What happens if all 3 servers are healthy and the normal network is fine for serving traffic to the VM consumers, but the switching network for data replication goes down? Is it possible to configure oVirt to "fail over" to the front-end network?I'm also wondering if its possible to do away with a switch all together, and just link the physical hosts together directly (like a cross-over cable) for the data replication. I'm also wondering what would happen in the following scenario: - All 3 servers are healthy - The out-of-band data replication network is healthy - 1 or 2 of the servers suddenly lost network connectivity on the front-end network What then? Would everything just keep working, and network traffic be forced to go out the healthy interface(s) on the remaining hosts? Sent with ProtonMail Secure Email.
