Dear all,

I faced issue when migrating instance by live-migration + 
block-migration guests floating IP became inaccessible. My setup are OVS 
+ DVR. Currently upgrading from Newton to Ocata.

Looks like when migration starts, in destination host neutron configures 
floating IP so traffic start to go to destination host but instance are 
still in source host.

Does live migration work correctly with DVR?

Best regards,

Martins
