Sparse allocation of vmstorage

Available vmstorage is calculated with the max size of the vdisks in the vmstorage location.

When creating vdisk with the sparse option checked. I get an error about the available diskspace.

It is impossible to do the following:

create a vm storage of 100G and than create a sparse allocated vdisk of 101G

When creating many small VM's with some storage 'flexibility' this forces you to allocate much more storage than needed for the actual vm storage.

Is this intended behaviour or am I missing something? It makes the kvm option on ODA 'expensive'.
