port down after live migration

[Mathieu Rohon]

I'm using live-migration with devstack and ML2 plugin (the same error occurs with the OVS plugin)
https://wiki.openstack.org/wiki/Devstack/LiveMigration

First of all, I think there is a bug in nova :
https://bugs.launchpad.net/nova/+bug/1224960

I've proposed a patch attached to this bug to resolv it quickly.

it seems that there is also something that goes wrong in neutron.
after live-migrating a VM, the port is correctly created on the new host and the dataplane seems correct. But the port is still down in the port table, and the vif-type is "binding_failed" in ml2_port_bindings table

it looks like the new host sends update_device_up, and its dataplane is correctly configured, but the previous host send update_device_down, that's why the port is getting down in database.

    change port status only if port is bound to the good host

    if host is set in the rpc message update_device_up/down sent by the agent,
    the port status will be changed only if the port is bound to the host.
