You are welcome to reopen that bug, specifying your use case for OvS. I cannot promise fixing this bug, as our resources are limited, and that bug, which was introduced in 4.2, was not deemed as urgently needed. https://gerrit.ovirt.org/#/c/86932/ attempts to fix the bug, but it still needs a lot of work. > > I know OVS is Experimental, but it worked in 4.1.x, and now we have to do a > step back to legacy bridge just to use 4.2.x, which in a vlan environment > just wreaks havoc (every VLAN need's a unique mac assigned to the bridge, > which vdsm does not do, so suddenly you get the kernel complaining about > seeing it's mac address several times.) Could you elaborate on this issue? What is wrong with a bridge that learns its mac from its underlying device? What wold like Vdsm to do, in your opinion? You can file a bug (or even send a patch) if there is a functionality that you'd like to fix. > > There is zero documentation on how to use OVN instead of OVS.
