Note however that it can not work as such because ioemu needs to perform
some domctls, which the hypervisor will not let the stub domain do. We
need to find a secure way to allow a domain to call memory/IO mapping
and IRQ/MSI binding domctls when it is allowed to, i.e. probably have
xend tell the hypervisor which PCI cards are controlled by which domains
and then accept domctls for their resources.
