Thanks for all the good discussions in the thread, and good we have 
consensus to move forward now.

still one open to hear suggestion though, regarding to how we want 
to pass the reserved regions to domain builder and hvmloader (for Xen 
we will extend related assignment hypercall to include per device override).

one simple solution is to extend xc_hvm_build_args and hvm_info_table 
to include specified regions, with the limitation on defining a fixed 
number (possibly use E820_MAX as a reasonable assumption)

another option is to place the information in xenstore which is more
flexible. However domain builder doesn't use xenstore right now (suppose 
extending use xenstore is not complex?)

or any other thought to be evaluated?

Thanks
Kevin
