[Libguestfs] --rbd volume access--

http://rwmj.wordpress.com/2013/03/12/accessing-ceph-rbd-sheepdog-etc-usin... I came across this link and and i was able to retrieve the rbd image. $ guestfish I was able to retrieve file from rbd image using the above method. Would you please let know how to do this in a single command line. I am getting the following error guestfish add /dev/null : config -set drive.hd0.file=rbd:ssd-clonetest-rule5/fullclone.img : run : list-partitions guestfish: invalid option -- 's' Try `guestfish -help' for more information. anything I m doing wrong here.
