I tried using Javascript (gjs) with GObject-Introspection and did a port of the create_disk example which is attached below. Quite a bit of time was spent looking up stuff in the GLib reference and guessing how certain idioms translate to gjs. I used the traditional add_drive_opts method since I haven't been able to find how to specify the optional arguments to add_drive_opts. How does that work?

This rather complex set of patches allow non-optargs functions to gain optional arguments, while preserving source and binary backwards compatibility. The problem is that we cannot add an optional argument to an existing function. For example, we might want to add flags to the 'lvresize' API which currently has no optional arguments.

how to use python-guestfs to access rbd device? The function i found is g.add_drive_opts, but i dono know how it receive ceph's configuration. I found this link http://rwmj.wordpress.com/2013/03/12/accessing-ceph-rbd-sheepdog-etc-using-libguestfs/ Is that the only way i should use to access ceph rbd? Can we use python-guestfs to get the same effect? Thanks

...'Permission denied' RuntimeError. Could someone kindly guide me the correct way to handle LVM disk as non-root user? Cause as http://libguestfs.org homepage claims, "libguestfs doesn't need root permissions." A little confused somehow. import guestfs g = guestfs.GuestFS() g.add_drive_opts("/dev/vg0/disk1", format="raw") Thanks! -- Qiu Yu
