it's exactly the behaviour i'd like to achieve (only disks available for common usage shown),
if you attached it to vm X and want detach it, go to vm/xx/disks/yy and detach it there,

(btw if we want support showing all disks in /disks, we should have link
from the disk->vm it attached to.)

the use-case is client-side filtering, in sdk i provide this capability where
it's not supported by ovirt-search (such as property based filtering etc.),
getting big chunk of not relevant data, is show-stopper for this feature.

in my other email, i suggested adding search-parameter for being able requesting
extended list, while the default should be reduced.
