Enable block live migration with attached volumes (partial)
Currently it is not possible to:
- Block live migrate instance which has additional volumes attached
- Block live migrate instance which uses config drive with iso9660 format
This blueprint aims this problem. Since libvirt 1.2.17 there is new API to select which devices should be migrated to destination host. It means that it is possible to exclude volumes or cd-rom from being migrated.

Marking this as partially complete, as the key part of this blueprint has actually been complete. The config drive one is really a separate bug, all be it related. The big issue here is we are missing the reno note for the big pice that been done. Marking as partially complete. --johnthetubaguy 2016.02.18
