Don't share privregs with hvm domain and twist IA64 xen dump core format slightly. Xen shares privregs pages with IA64 HVM domain for xm dump-core to dump the pages. However sharing the page allows hvm guest domain peek/destroy the page contents that might cause xen crash. And the xen dump core file doesn't need privregs page because cpu context should be obtained from vcpu context in case of IA64 HVM domain. Although this patch modify xen dump core format, current crash utility (at least crash 4.0-4.7) doesn't look into .xen_ia64_mmapped_regs section and I don't know any other tools to understand xen dump core file. So this format modification doesn't cause incompatibility issue. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>
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.
