XEN_BACKEND doesn't actually depend on XEN_DOM0. DomUs can serve backends to other DomUs. One example is a service VM providing network backends.
The original Kconfig defaulted Dom0 to y and it could be disabled. DomU could not select the option. With the new Kconfig, we default y for Dom0 and n for DomU. Either can then toggle the selection.
Signed-off-by: Jason Andryuk <jandryuk@gmail.com> --- OpenXT runs network backends in a network service DomU that shares out PCI NICs.
