The device tree based boot protocol is extended to carry information

Please consider also status monitoring and restarting for those domains.

  DomUs created this way don't have access to xenstore for the
moment. This is actually OK, because this is meant for mission critical
applications that typically only access directly assigned devices. They
cannot tolerate interference or increased IRQ latency due to PV
protocols.
But even a mission critical application does exchange some information with other entities in the system. So they would need interdomain communication anyway (i.e. built with event channels and shared pages, etc.)
