[ovirt-users] Re: Request for feedback about "Overview of Networking in oVirt"

Thanks for putting in the effort! I learned a lot of new things. I also learned that I need to learn a few more now. The table could use some alternating background or a grid: Too easy to get lost. Environments change over time, e.g. you find you really should have split the management, storage, migration and north-south networks, but any documentation I find says "do it right from the start". So I wonder if there is any easy enough way to split out the storage network to a newly added second set of NICs in a HCI environment, or if a re-install is really the only reasonable thing to do. They have created such a nice looking GUI around the whole network configuration stuff, but from what I have experienced, just hitting buttons is very dangerous there, while many don't have a description of help item. Since you're at it: I have been able to make nested virtualization work to a degree. 3-node HCI (physical) is hosting another 3-node HCI (virtual), virtual oVirt Cockpit deployed a working gluster, launched and prepared the HostedEngine the nested level, managed to move it on the Gluster and if I boot the virtual nodes, their VDSM will launch the nested hosted engine, but that machine can't see the network any more. I can connect to it via hosted-engine --console, it has an Ethernet interface, but no traffic gets through either way: Ideas? What do I look for? I am wildy guessing that ovn has nesting issues, so would going the Linux bridge approach help there? How do I chose between the two? Must I leave my beloved Cockpit wizard and use the script installer?
