I think there is such a use-case in clustered environments (DB cluster, for example), in
which you have several disks that are not shared (OS, applications, etc.), and several
disks that are shared (DB disks).
In this case, in order to create this clustered environment, it will be nice if you
create a template with the regular disks, create a pool from it, and attach all the VMs in
the pool the shared DB disks.
(It would be even nicer if the shared disk will be a part of the template, and when
creating VMs from it they will have have a "link" to this shared disk - but I
agree that it may be complex so maybe we should leave it aside for now).
Thoughts?
that we can wait with an interesting enough use case before we pursue
this and ignore it for simplification for now.
