However, it is possible that vpc/vhd has new features that are not yet supported in QEMU. There is a listed project idea for updating image formats on the GSoC wiki page: http://wiki.qemu.org/Google_Summer_of_Code_2011#Improved_image_format_compatibility You could assess QEMU's implementation in block/vpc.c and compare against the latest public file format specification: http://en.wikipedia.org/wiki/VHD_(file_format) If you find there are new features or format changes that are not yet supported in QEMU, this might make a good "Improved image format compatibility" GSoC project.
