Hi,
I’m seeing the ovs-vswitchd process disconnect its UNIX socket, and am
wondering if it’s anything to worry about. My Openflow client is able to
re-attach and work again, and it only seems to be at startup time.
Here’s the switch log (/var/log/openvswitch/ovs-vswitchd.log:

Here is a little more detail.
VMtest-A is sitting on 10.181.6.75. VMtest-B is sitting on 10.181.6.76. Both
VMs use eth0 which are seen on the OVS VM as eth3 and 4 respectively. As you
can see from the ova-vsctl show in the original email, both are access ports
and are on vlan 104.

Hello,
I had to use 2 switches/bridges to reproduce the problem. Logs in attachments.
Just for the time orientation:

and when it finds out that it is the first connection from that device, it
sends master then)

Hi all,
we're trying to set up a SDN network with 3 ovs over a ring topology with
in-band control.
When we link the ovs instances to the SDN controller, a loop is generated
(of course). If we enable the STP before linking the switches to the
controller, one of the link remains disabled (thing we

Hi Lui Chao,
There is a known bug in ovs v2.5.0 that prevents vhost user receiving
packets when a version of QEMU lower than 2.5.0 is used. (details at
http://openvswitch.org/pipermail/dev/2016-March/068282.html). It has
been fixed in the repository, then you should clone the ovs repo and use

the second is megaflow cache. But I donot know the difference between megaflow

Thanks for your patience, it really helps me a lot. And I run it
