If you're up for doing some work, I'd recommend that approach as it will not only solve your problem but also bring the community a step closer to a de-privileged dom0.

I agree with this (although the original enquirer may find that this is not necessarily the most expedient path to solving their problem).

I would not recommend using the Xen Security Modules arrangements. There are quite a few bugs in this code, including some very serious security bugs (which sadly we aren't allowed to give more information about as the reports were embargoed).

Unfortunately turning on the XSM support is likely to result in a substantially less secure system.
