Comment 31 for bug 1560965

As my hat of horizon team, I would like to clarify the current situation. This bug is now associated with horizon, nova and cinder.

Regarding the boot from volume, horizon talks with only Nova API, so the problem can be split into two parts:
(a) create-server parameters which passed from horizon to nova
(b) nova and cinder behaviors around create-server with boot-from-volume

The following are questions from horizon side:

(1) Is the problem only (a) above?
(2) If (1) is yes, Apart from test code, does a patch attached n #20 solve the problem?
(3) If (1) is no, can we use this bug on focusing (a) and split (b) as a separate bug?

We don't have Xen hypervisors, so we cannot actually test it. I think this is the main reason horizon team failed to address this for a long time. Hopefully, someone who can test Xen hypervisors can propose a fix.
