Handle new boolean option discard/no-discard for disk configuration. It is supposed to disable discard support if file based backing storage was intentionally created non-sparse to avoid fragmentation of the file. The option intended for the backend driver. A new boolean property "discard-enable" is written to the backend node. An upcoming patch for qemu will make use of this property. The kernel blkback driver may be updated as well to disable discard for phy based backing storage.

xen-bugtool =========== The xen-bugtool command line application will collate the Xen dmesg output, details of the hardware configuration of your machine, information about the build of Xen that you are using, plus, if you allow it, various logs. The information collated can either be posted to a Xen Bugzilla bug (this bug must already exist in the system, and you must be a registered user there), or it can be saved as a .tar.bz2 for sending or archiving. The collated logs may contain private information, and if you are at all worried about that, you should not use this tool, or you should explicitly exclude those logs from the archive. xen-bugtool is wholly interactive, so simply run it, and answer the questions.
