SimNow not emulating xsave in hwemu_family15.bsd

[Andre Przywara <andre.przywara@amd.com>]

Hi,

while trying to use the latest Xen unstable inside SimNow, I learned 
that despite the respective CPUID flag is set, SimNow does not emualate 
at least the xsetbv instruction (part of to the XSAVE feature).
SimNow will answer with exception #6 (#UD) and Xen will crash. The CPUID 
bit is set, though (as in the real BD). When turning this bit off (in 
debugger: rMc0011004=1298220B178BFBFF, is there an easier way?), Xen 
will avoid the xsetbv call and the guest creation process continues.

Can the SimNow tell us the recommended .bsd we should use for testing 
SVM features?

Thanks and
Regards,
Andre.
