Thomas,
Are you booting with the policy in enforcing or permissive mode? We're
using the same configuration here but only in permissive mode. I see some
policy violations in the xen dmesg. (We're overdue for some updates to the
sample policy to include some organizational cleanups.) I suspect you are
running in enforcing mode and simply need to update your policy. The
iomem/ioports/irq_permit/deny_access have security checks in the
add/remove_rangeset codepaths. These are the only xsm hooks relevant to
your report and flask will cause rc != 0 in enforcing mode.
Which changeset, HEAD is too relative.
George
