I found some resources on the QCOW formats, and integrated the results into magic/Magdir/msdos:
http://www.gnome.org/~markmc/qcow-image-format-version-1.html http://www.gnome.org/~markmc/qcow-image-format.html I ran into two issues, but they're not showstoppers. (1) The backing-file name isn't stored in a NUL-terminated format; pretending that it's NUL-terminated seems to work, but since I couldn't figure out how to specify a string length based on an indirect value, it's not being done the *right* way. (2) The offset to the backing-file name in qcow2 images is a 64-bit quantity, but there's no way to put in a 64-bit offset. I cheated and assumed that the top four bytes are zero; this works on newly-created images, at least, though I can't guarantee that it'll work in the general case. I've attached a debdiff against 4.26-2 which overhauls QEMU image detection in a number of ways--the magic number was incomplete, size detection didn't work properly, and the output had a lot of whitespace in it--if there's anything I need to do for the patch, please let me know.
