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.
