Thread-topic: [Xen-devel] [PATCH][HVMLOADER][DISCUSS] 8 way default rombios
ACPI MADT is sufficient for getting >1 vcpus (just add vcpus=N at xm
create time) for modern OSes, but the mp config table would be required
for old guests. So I think the patch is sensible.

Subject: [Xen-devel] [PATCH][HVMLOADER][DISCUSS] 8 way default rombios

Attached simple patch modifies the rombios and hvmloader Makefiles to
default to an 8-way bochs bios for the hvmloader.

Is there a reason to not define the mp config table by default for >1
processors (8), in the repository?

Seems like using the hvm guest config file can the methodolody to
describe a UP guest regardless of the mptables. 
Defaulting the rombios to MP would allow users to experiment with SMP
guests, while allowing UP guests to work.
