With proper permission (and, for the I/O port case, wrap-around) checks
added (note that for the I/O port case a count of zero is now being
disallowed, in line with I/O memory handling):
XEN_DOMCTL_irq_permission:
XEN_DOMCTL_ioport_permission:
Of both IRQs and I/O ports there is only a reasonably small amount, so
there's no excess resource consumption involved here. Additionally
they both have a specialized XSM hook associated.
XEN_DOMCTL_iomem_permission:
While this also has a specialized XSM hook associated (just like
XEN_DOMCTL_{irq,ioport}_permission), it's not clear whether it's
reasonable to expect XSM to restrict the number of ranges associated
with a domain via this hook (which is the main resource consumption
item here).

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.
