Hi Maxiao:
Thanks for your reply.
This flow indeed been updated, when ovs receive any packets sent from migrated
vm. The flow in table10(br-tun) is used to learn the mac address, and put the
learned flow into table20. It just takes longer to complete.
And is there any way to update the flow faster? thanks!

Hi, JingTing
The flow should be updated after the rarp broadcast packet be send by qemu.
So I think you should make sure whether the broadcast packet has been send and
received by the host.

Hi guys:
The bug has be reported on https://bugs.launchpad.net/neutron/+bug/1541738
The flow in br-tun as below is generated by learning flow, and not updated
immediately after vm live migration.
Original flow:
cookie=0x0, duration=194.884s, table=20, n_packets=0, n_bytes=0,
hard_timeout=300, idle_age=194,
priority=1,vlan_tci=0x0306/0x0fff,dl_dst=5a:c6:4f:34:61:06
actions=load:0->NXM_OF_VLAN_TCI[],load:0x1ef->NXM_NX_TUN_ID[],output:24
Updated flow:
cookie=0x0, duration=194.884s, table=20, n_packets=0, n_bytes=0,
hard_timeout=300, idle_age=194,
priority=1,vlan_tci=0x0306/0x0fff,dl_dst=5a:c6:4f:34:61:06
actions=load:0->NXM_OF_VLAN_TCI[],load:0x1ef->NXM_NX_TUN_ID[],output:26
Anyone has idea how to update this flow proactively.thanks!
