I think this would support Daniel's use case. But how do you deploy a VM
manually? I.e how do you by-pass the scheduler (except by creating a
"WILD" vm)? 

At the moment the multi DS support is configured at template level. From a
"system" perspective it would be nice to be able to control which
datastore gets used. For example filter on user, group, vm template
attributes, etc. At least we have a use case for this (seperate "Qtree"
per datastore for IO billing). It proably makes the scheduler's life
more complicated :(.

Yes, it's definitely useful.
