I read openvswitch document completely about openvswitch http://opennebula.org/documentation:rel4.2:openvswitch
there is 2 way for using openvswitch, i can implant second way (*ovswitch_brcompat) *but this way is deprecated *Bridge compatibility is deprecated and may be removed no earlier than February 2013* now but when I'm using first way, (using from openvswith without *brcompat *and use from brctrl instead), opennebula when deploying new vm get error. Wed Sep 4 06:05:28 2013 [VMM][I]: post: Executed "sudo /usr/bin/ovs-vsctl set Port vnet0 tag=550". Wed Sep 4 06:05:28 2013 [VMM][I]: ovs-ofctl: br0 is not a bridge or a socket Wed Sep 4 06:05:28 2013 [VMM][E]: post: Command "sudo /usr/bin/ovs-ofctl add-flow br0 in_port=,dl_src=02:00:ac:14:04:04,priority=40000,actions=normal" failed. Wed Sep 4 06:05:28 2013 [VMM][E]: post: ovs-ofctl: dl_src=02:00:ac:14:04:04: bad syntax for in_port Wed Sep 4 06:05:28 2013 [VMM][E]: ovs-ofctl: dl_src=02:00:ac:14:04:04: bad syntax for in_port the main problem is that br0 is not created with openvswitch and create with brctl :) but for solve this problem, I create fake bridge with openvswith # ovs-vsctl add-br br0 # ovs-vsctl add-port br0 eth1 # ovs-vsctl add-br br10 br0 10 # ovs-vsctl list-br br0 br10 so I inform to opennebula, br10 is my bridge now problem is ovs-ofctl using br10 instead br0 and i get error from ovs-ofctl . in this situation, ovs-vsctl must use fake bridge (br10) and ovs-ofctl must use real bridge (br0) until anything work well
