Are you planning > to support the funky QCow / VMDK formats too ? Yes, interesting point. Since I always use flat files or straight partitions for my guests I admit I hadn't given this much thought :-) However support for these formats is just a matter of decoding enough of the structure to enable the same mappings to be made in the 'virt-df' library, same as for LVM2 or indeed MBR partitions now. I'll take a look at it. IIRC there are several different undocumented variations on the QCow format?
