Dom0 is another name for the host operating system. It has access to,
and manages all the physical hardware devices, and provides the mgmt
of the DomU guest operating systems. The reason getting a working Dom0 
is a harder bit  of work than DOmU, is precisely because it has to manage
all the hardware and work with the hypervisor. The DomU only ever sees
virtual hardware devices (ignoring PCI passthrough), so its a much
simpler beast.
