[ovs-discuss] DPDK OVS with vhostuser problem

[Eli Britstein]

Hi



I followed the instructions in INSTALL.md and INSTALL.DPDK.md.

I have created two ports in a bridge, and set the flows 1<->2.

Doing ovs-ofctl dump-flows br0 shows it right.

The purpose of this setup is to measure latency of those ports (using a simple ping).



I invoke a VM, with those 2 ports. It gives those messages:

2016-03-02T17:08:17.410601Z qemu-system-x86_64: -netdev type=vhost-user,id=mynet1,chardev=char1,vhostforce: chardev "char1" went up 2016-03-02T17:08:17.410851Z qemu-system-x86_64: -netdev type=vhost-user,id=mynet2,chardev=char2,vhostforce: chardev "char2" went up



>From within the VM (qemu), I have eth0 and eth1.

I configure them as:

ifconfig eth0 1.1.1.1

ifconfig eth1 1.1.1.2



Ping will fail though:

ping 1.1.1.2 -I eth1 obviously works.

ping 1.1.1.2 -I eth0 fails.



In the host, I wanted to see some statistics, but ovs-ofctl dump-flows br0 fails, with this message:



ovs-ofctl: /usr/local/var/run/openvswitch/br0.mgmt: failed to open socket (Connection refused)



I see that this issue is right after invoking the VM.



1. What do I do wrong?

2. How can I track the packets to see why they are not forwarded correctly?



Thanks,

Eli
