Hi,

after upgrading from Xen 3.2.1 to 4.0.1 (Debian) my HVM instance on a qcow file backed qcow image won't boot anymore. That's not a problem though, the problem is that the image was silently modified (found the conversion hint in the logs afterwards) and now it also won't boot on my not yet upgraded backup system :\ Is there a way to reverse the conversion or some other way to access the data? I've already taken a look at block-qcow.c where the conversion takes place but my C skills are pretty limited so I wasn't able to reverse it...

Regards
