I don't really know what point it serves, but if we are to explicitly
handle OVF, then we will have to cope with multi-disk OVF packages.
I think unpacking them at glance would probably not be the right
think todo, because it is making assumptions about how a virt
driver will want to consume the OVF. Better to keep it packed in
glance and let the nova virt drivers figure out how they want to
unpack things
