Hi Anthony,

   Does that mean SMP HVM guests work with this patch?  I was wondering
if HVM_INFO is how x86 is setting up the number of vCPUs.  I removed the
code in tools/libxc/ia64/xc_ia64_hvm_build.c that appeared to handle
this, so thought we might need to migrate to something like HVM_INFO to
do that now.  PAE is x86 specific of course, but it's part of the
generic HVM params.  It won't hurt anything to set the parameter on
ia64, it just won't do anything.  Maybe after 3.0.4 it would be
worthwhile to create an interface for setting arch-specific parameters.
