OVN is aleady using GENEVE, VXLAN or STT tunnels (the user can choose any), so the isolation is already assured. The scripts provided by ovirt configure a geneve tunnel. You are free so override this manually to vxlan or stt if you want, let me know if you need any howto info.
yes, please. I have used in the mean time the vdsm-tool command that takes care of creating the default geneve tunnel In my case vdsm-tool ovn-config 10.4.168.80 10.4.168.81 but I would like to know how to manually use other types too. I watched the deep dive demo about ovn but at the bottom of the related slide there are three lines that should be equivalent to the above command, something like ovs-vsctl set open ? external-ids:ovn-remote=tcp:10.4.168.80:6642 ovs-vsctl set open ? external-ids:ovn-encap=type=geneve ovs-vsctl set open ? external-ids:ovn-encap-ip=10.4.168.81 The ? character seems a dot or a comma, I have not understood the syntax.... (what are the accepted words for type= in the second line?) Thanks again, Gianluca
