Our testing with 17193 indicates that pae HVM guests (using shadow
paging) on pae hv fail if attempting to use >4Gig of memory (3840). 
Is this change on purpose?  Or should HVM shadow guests (hap=0 in guest
config) be allowed to use up to 8Gig as previously supported.  

We have only tested on AMD-V, so don't know about VT boxes. 
Thanks for any info,
tom
