Err, strong NACK. Please don't start messing with the contents of the
data plane, we're getting into real trouble there. It's perfectly
valid for a guest to create an image inside an image, and with hardware
support for nested virtualization I guess this use case will become
rather common, just as it already is on S/390 with VM.
Note, this is limited to raw.
If you use qcow2 in L0, the guest can do whatever it wants to do.
But if we autoprobe a raw image, we simply cannot let a guest turn the
raw image into something else.
A user can still use raw images and let them contain anything, but they
have to explicitly specify that it's a raw image.
