[Bug 1497125] Re: fail to live-migrate a booted from volume vm which have a local disk.

 

@ Hiroyuki Eguchi:

I assume that this is a thing which needs a blueprint [1] and a spec file [2] to discuss it.
I'll recommend to read [3] if not yet done. To focus here on bugs which are a failures/errors/faults
I close this one as "Invalid". The effort to implement the requested
feature is then driven only by the blueprint (and spec).

If there are any questions left, feel free to contact me (markus_z)
in the IRC channel #openstack-nova
