hi guys I'm trying a typical, I'd presume, setup: two libvirt hosts with one lxc guest each. boxA: $  ovs-vsctl show 1a6a2e4f-11f3-48df-becd-03b59d00a1fb     Bridge "ovsbr0"         Port nm-team             trunks: [55]             Interface nm-team         Port "vnet12"             trunks: [55]             Interface "vnet12"         Port "ovsbr0"             Interface "ovsbr0"                 type: internal     ovs_version: "2.0.0" boxB: $  ovs-vsctl show 05ffa96c-a961-41e7-9f8a-74dbe214153a     Bridge "ovsbr0"         Port "vnet41"             trunks: [55]             Interface "vnet41"         Port nm-team             trunks: [55]             Interface nm-team         Port "ovsbr0"             Interface "ovsbr0"                 type: internal     ovs_version: "2.0.0" In libvirt openvswitch network defines & starts okey, both guests start okey, yet guests cannot ping one another. Ifaces in guests seem to instantiate okey cause each guest can ping its own IP (on libvirt openvswitch net) You can see that on each host openvswitch port is nm-team, which I presume must be pretty "regular" situation. Only thing I'm not sure is that the same nm-team (on each host) is also a port to NM's bridge. (which works fine, these bridge ifaces on both hosts ping each other no problems). Which bits I get wrong or am missing? many thanks, L.
