I can and Xen can do so too :-)

Sorry, I forgot about blktap...

blktap requires a certain cluster size for qcow images IIRC. That's probably why qemu-img doesn't work.


Anthony Liguori

I just followed the description in [1].

And the point is as i have explained: it works with qcow-create created
images but not with qemu-img created images.

I do not know if that is by design or a bug.

IMHO the Xen qcow format is compatible with qemu so it should work.
