Hi list,
This is my first post, please be gentle.
I've come in contact with openvswitch, because it is used in our
hypervisor (Citrix XenServer 6.1).
I'm still reading the documentation, so I'm not totally into it yet.
The problem I'm having, is that I have a physical switch (HP FlexFabric
in a HP C7000 chassis) that sends LLC packets to every vlan (4096) every
5 seconds.
This means openvswitch sees those packets on all interfaces and
processes them.
Here's a tiny snippet of the the LLC flows (ovs-dpctl dump-flows
system@xapi1):
in_port(1),eth(src=44:1e:a1:78:50:c1,dst=01:14:c2:44:1e:cc),eth_type(0x8100),vlan(vid=3753,pcp=0),encap(),

The flow count is jumping between 800 and almost 10000 every 5 seconds.
When pinging the ONLY VM (which is idle) on this xenserver host from
hypervisor to VM, I observe the following:
[root@xenserver ~]# while true ; do echo -e "$(date) ping: $(ping -c 1
1.1.1.1 | grep '64 bytes')\t$(ovs-dpctl show xapi1| grep flows)" ; sleep
0.2 ; done

As you can see, there are spikes over 100 ms in this output.
This is definately related to ovs-vswitchd cpu usage (spike every 5 sec):
