Comment 4 for bug 746821

I can reprodule this issue. Here is a detail explanatioin.

The procedures of live-migration is,
1. destination compute node prepares volumes/secgrp/etc config for coming instances
2. src compute node migrates instance to destination compute node.
3. src compute node updates db records.

Regarding to 1 above, destination compute node creates nwfilter-instance-instance-<id> through libvirt.
But because of multinic changes, nwfilter-instance-instance-<id>-<nic> is necessary, so some changes at nova.virt.libvirtConnection are necessary.
