The previous default of "permissive" is meant for developing or debugging a disaggregated system. However, this default makes it too easy to accidentally boot a machine in this state, which does not place any restrictions on guests. This is not suitable for normal systems because any guest can perform any operation (including operations like rebooting the machine, kexec, and reading or writing another domain's memory). This change will cause the boot to fail if you do not specify an XSM policy during boot; if you need to load a policy from dom0, use the "flask=late" boot parameter. Original patch by Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>; modified to also change the default value of flask_enforcing so that the policy is not still in permissive mode. This also removes the (no longer documented) command line argument directly changing that variable since it has been superseded by the flask= parameter.

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.
