It's very tricky and not as straight forward using ovs-vsctl commands. It must be done in the gui and check make sure vmbr0 are both active and autostart (using the command method, I can't never get the bridge active). All configs are written into /etc/network/interfaces and sometime requires small modificationAny tips on setting that up?
Right now I am trying to create a linux bond and attache it to a OVS bridge on another node, so far with no success, I guess I need to use OVS Bond instead.
Lastly, don't create any vm until you have setup the cluster or otherwise its impossible to create a cluster with nodes that has a same vmid. Also, once the cluster is created, you cannot change the hostname nor its IP (now I understand the beauty of openstack) SD Networking on pve 4.0 is very tedious
For IB ports, I am trying to get sr-iov working so that I don't have to use a linux bridge for the IB to eth
