This option can be used for passing file descriptors on the
command line.  It mirrors the existing add-fd QMP command which
allows an fd to be passed to QEMU via SCM_RIGHTS and added to an
fd set.

This can be combined with commands such as -drive to link file
descriptors in an fd set to a drive:

     qemu-kvm -add-fd fd=3,set=2,opaque="rdwr:/path/to/file"
              -add-fd fd=4,set=2,opaque="rdonly:/path/to/file"
              -drive file=/dev/fdset/2,index=0,media=disk

This example adds dups of fds 4 and 5, and the accompanying opaque

s/4 and 5/3 and 4/

Doh.. thanks.
