 ping from guest to host.

 Ok, my setup was:

Host<------->openVSwitch<----------->guest
      LOCAL               vhostuser

 So, in order to migrate the guest, i simply replicated this setup on =
both hosts, with the same IPs on host side. And on both hosts i set up =
the following ruleset for openvswitch:

ovs-ofctl add-flow ovs-br0 in_port=3D1,actions=3Doutput:LOCAL
ovs-ofctl add-flow ovs-br0 in_port=3DLOCAL,actions=3Doutput:1

 And on the second host, for some reason, vhostuser port got no 2 in the =
database instead of 1. Probably because first i added wrong port, then =
added correct one, then removed the wrong one. So, as i wrote before - =
please don't worry, the patch works fine, it was totally my lame fault.
