Dear all, I am testing a setup where two VMs have to communicate using vhost-user ports, it works using OvS 2.4 but it does not work with the master version nor with 2.5.
The setup is quite simple, a pair of VMs connected to OvS using vhost-user ports, two flows configured to forward the packets between the VMs, ping is used to test connectivity between the VMs (ips and routing tables are configured). The problem that I can see is that a vhost-user port is dropping packets on transmission: OFPST_PORT reply (xid=0x2): 3 ports port 1: rx pkts=330, bytes=14172, drop=?, errs=0, frame=?, over=?, crc=? tx pkts=0, bytes=0, drop=8, errs=?, coll=? port LOCAL: rx pkts=0, bytes=0, drop=0, errs=0, frame=0, over=0, crc=0 tx pkts=0, bytes=0, drop=0, errs=0, coll=0 port 2: rx pkts=8, bytes=648, drop=?, errs=0, frame=?, over=?, crc=? tx pkts=0, bytes=0, drop=330, errs=?, coll=? I found that somebody has a similar problem: http://openvswitch.org/pipermail/dev/2016-March/067152.html, I tried to change pmd-cpu-mask but the problem is always there. I did some debug and the problems is that qid is always -1 in the function __netdev_dpdk_vhost_send. Here it is some extra debug info: ovs-vswithd.log: http://pastebin.com/2CUyjGED ovs-vsctl show Bridge "br0" Port "br0" Interface "br0" type: internal Port "vhost-user-2" Interface "vhost-user-2" type: dpdkvhostuser Port "vhost-user-1" Interface "vhost-user-1" type: dpdkvhostuser ovs-appctl dpctl/show netdev@ovs-netdev: lookups: hit:411 missed:1 lost:0 flows: 1 port 0: ovs-netdev (internal) port 1: vhost-user-1 (dpdkvhostuser: configured_rx_queues=1, configured_tx_queues=1, requested_rx_queues=1, requested_tx_queues=9) port 2: br0 (tap) port 3: vhost-user-2 (dpdkvhostuser: configured_rx_queues=1, configured_tx_queues=1, requested_rx_queues=1, requested_tx_queues=9) ovs-appctl dpif-netdev/pmd-rxq-show pmd thread numa_id 0 core_id 0: port: vhost-user-1 queue-id: 0 port: vhost-user-2 queue-id: 0 Thank you very much, Mauricio V, _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
