From: Luca Miccio <lucmiccio@xxxxxxxxx> During domU creation process the colors selection has to be passed to the Xen hypercall. This is generally done using what Xen calls GUEST_HANDLE_PARAMS. In this case a simple bitmask for the coloring configuration suffices. Currently the maximum amount of supported colors is 128. Add a new parameter that allows us to pass both the colors bitmask and the number of elements in it.
