That is exactly the case : it is indeed a pure data disk with an ext3 
filesystem (no LVM, no nothing).
I intend to attach it to some existing VM.

I know how to convert it into qcow2 or whatever.
I know how to create an additionnal disk in oVirt.
I know I could trick the system by creating a disk in oVirt, then 
replace its content by playing with dd, or exploring LVs indide my 
domain master LUN.

But I must admit I was dreaming of some 'official' way to do that.
