Public bug reported:

User rebuild a instance booted from volume in the following steps.

1. Stop a instance
2. Detach a root device volume.
3. Attach a new root device volume.
4. Start a instance

But, currently, It's impossible by these reasons.

1. User not allowed to detach a root device volume.
   - detach boot device volume without warning 
     (https://bugs.launchpad.net/nova/+bug/1279300)

2. User not allowed to attach a root device volume expect when creating a instance.
   - A get_next_device_name which is executed when attaching volume, never return a root_device_name.
