Comment 1 for bug 1839422

As you may know, the response of volume_list() is used to show image name for boot-from-volume instances (i.e. servers).

Your suggestion works only when all instances are not booted from volumes. If one instance is booted from a volume, volume_list() will be called after server_list() and it means the instance panel takes more time than now.

The possible solutions I see are:

(1) to keep the current implementation as-is
(2) to add an option not to show image names for boot-from-volume instances (this is pre-stein behavior)
(3) to follow mashuting's suggestion (it only works when *all* instances do not use boot-from-volume)

Thought?
