Hello list, Just started using openvswitch and ran either into a bug or I am missing something. According to various mailing list emails, MPLS label operations are available in userspace datapath. To configure a vswitch in the userspace DP, it needs to be set as a “netdev”, but after doing so, all vswitch operational commands fail with "br0 is not a bridge or a socket”.
Found a similar report from back in October: http://openvswitch.org/pipermail/discuss/2014-October/015138.html <http://openvswitch.org/pipermail/discuss/2014-October/015138.html>, but I can’t find if the specified commit made it into 2.3.1 or this is a regression bug. Here is the sequence of commands to reproduce (same error for ovs-ofctl add-flow): root@pve:~# ovs-vsctl -V ovs-vsctl (Open vSwitch) 2.3.1 Compiled Dec 27 2014 11:00:30 DB Schema 7.6.2 root@pve:~# ovs-vsctl del-br br0 root@pve:~# ovs-vsctl add-br br0 root@pve:~# ovs-vsctl add-port br0 eth1 root@pve:~# ovs-vsctl add-port br0 tap100i0 root@pve:~# ovs-ofctl show br0 OFPT_FEATURES_REPLY (xid=0x2): dpid:0000000c29e93542 n_tables:254, n_buffers:256 capabilities: FLOW_STATS TABLE_STATS PORT_STATS QUEUE_STATS ARP_MATCH_IP actions: OUTPUT SET_VLAN_VID SET_VLAN_PCP STRIP_VLAN SET_DL_SRC SET_DL_DST SET_NW_SRC SET_NW_DST SET_NW_TOS SET_TP_SRC SET_TP_DST ENQUEUE 1(eth1): addr:00:0c:29:e9:35:42 config: 0 state: 0 current: 1GB-FD COPPER AUTO_NEG advertised: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG supported: 10MB-HD 10MB-FD 100MB-HD 100MB-FD 1GB-FD COPPER AUTO_NEG speed: 1000 Mbps now, 1000 Mbps max 2(tap100i0): addr:ae:6f:8b:e7:50:3a config: 0 state: 0 current: 10MB-FD COPPER speed: 10 Mbps now, 0 Mbps max LOCAL(br0): addr:00:0c:29:e9:35:42 config: PORT_DOWN state: LINK_DOWN speed: 0 Mbps now, 0 Mbps max OFPT_GET_CONFIG_REPLY (xid=0x4): frags=normal miss_send_len=0 root@pve:~# ovs-vsctl set bridge br0 datapath_type=netdev root@pve:~# ovs-ofctl show br0 ovs-ofctl: br0 is not a bridge or a socket Regards, Andrei
