Document and implement a new option that permits disk backends which would otherwise have to avoid O_DIRECT (because of the network memory lifetime bug) to use it anyway. This is: direct-io-safe in the xl domain disk config specification direct_io_safe in the libxl disk API direct-io-safe in the backend xenstore interface Add a reference to xen/include/public/io/blkif.h in docs/misc/vbd-interface.txt.

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.
