Robert Collins cb62bae9b8 Build images using loopdev instead of qemu-nbd. ... Qemu-nbd does not perform well with older versions of qemu due to the lack of writeback caching mode. It also only builds qcow2 images and there is a desire for raw image support. Finally, qemu-nbd makes it very difficult to build images concurrently due to the somewhat opaque nature of how it selects a /dev/nbd# device. losetup, on the other hand, makes this process very straight forward.
