Works!!!

Despite at this traceback all works well. Problem was with iptables. I
forgot open port 16509
in libvirtd.log I found:

09:11:13.640: 27387: error : virNetSocketNewConnectTCP:432 : unable to
connect to server at '192.168.0.1:16509': No route to host
09:11:13.640: 27387: error : doPeer2PeerMigrate:2128 : operation failed:
Failed to connect to remote libvirt URI qemu+tcp://192.168.0.1/system

What 404 in this trace means for nova?It's raised only when I want to
migrate to compute node from main controller. On node only nova-compute
works.
