I've thought about that a bit more and for now we can go with leaving it
in the common utils file. Despite being qemu specific, the storage
driver uses the APIs too and we should be able to use the backing files
created by qemu in the storage driver too so please disregard this point
for now.

Well, since you've posted this after you've received the review on the
qemu part where it was almost certain that the design of the qemu part
would change it didn't make much sense to post this since it wasted your
time writing the code and even if the rest of the code would be in good
shape you'd still need to post another version with the changed naming.
