Ah - I expected that with something as

disk = [ 'file:mydisk.img,hda,w' ]

Xen would have directly used "mydisk.img" as the backend disk file. Does 
it instead automatically create a loopback overlay?

I mainly use KVM, and maybe I am spoiled by its capability to use 
basically any datastore as backing disk.
Thanks.
