This series adds command line file descriptor passing support to the -drive option. This is a follow-on to the existing QMP fd passing support provided in the following patch series: comments.gmane.org/gmane.comp.emulators.qemu/165463 An example of using the new -drive fd and opaque options: qemu-kvm -drive fd=24,opaque="rdwr:/path/file",index=0,media=disk When an fd, and optionally opaque, are passed with -drive, they are added to an automatically generated fd set. The file name is also generated in the form of "/dev/fdset/nnn", where nnn is the fd set ID. qemu_open() already knows how to handle a filename of this format. qemu_open() searches the corresponding fd set for an fd and when it finds a match, QEMU goes on to use a dup of that fd just like it would have used an fd that it opened itself.
