QEMU is fully capable of handling VDI images and we just refuse to
work with them. As qemu-img knows and supports this, there should be
no problem with this addition.
This is of course, just basic functionality, without searching for any
backing files, etc.

It's very much possible that I missed something when adding this
"functionality", I just tested running a machine and creating a volume
using 'virsh vol-create-as'. So feel free to point out mymistakes.

We can do better than that - look at block/vdi.c in QEMU GIT tree
to find out the offsets / values for version number, magic signature
at least, even if you ignore backing files for now.
