15:47:19 ignaziocassano I have just tryed again now. Startded I new vm. It responds to pings. Migrated it on new node. It stops to respond. I logged into vm using the console and I pinged the default router. It started immediately to respond to ping requests

15:49:17 sean-k-mooney ignaziocassano: can you do that again but this time use tcpdump or tshark to dump the traffic

15:52:32 sean-k-mooney if you log into the souce node and check the name of the tap device you can set up a watch command that will try do start dumping the packets

15:53:40 sean-k-mooney basicaly what im wondering is will you see the RARP packets form qemu and will they be recived before ovs is configured

15:54:04 sean-k-mooney you coudl similarly check on teh br-ex/phsyical interface connected to ovs

16:04:00 sean-k-mooney so the question is has the ovs agent finished installing the openflow rules wehn that was sent and did tha tpacket also get sent on the physical network correnctly encapsulated

16:06:45 sean-k-mooney cool so we can see that the RARP packets are sent but we need to look at the timestamp and compore that to the neutron agent logs
