Public bug reported:
Nova fails all live migrations on dedicated interface due to conversion
of string to unicode (in Python 2.7).
My environment:
* nova trunk, commit 40f9b0ad16d3a5fae184bbe6d4a49cf792967089
* QEMU 2.6
* Libvirt 1.3.4
1. Set live_migration_inbound_addr to IP address of existing interface
2. Make sure that live_migration_tunnelled is set to False
3. Restart nova-compute
4. Try to live migrate any instance
5. Outcome:
2016-11-02 12:26:04.272 DEBUG nova.virt.libvirt.driver

This happens to me everytime when trying to live migrate any VM over
