RE: [Xen-devel] VMX status report. Xen: #17702 & Xen0: #559 -- nonew issue

Hi, Keir, 
    I think the problem may be not in the tools side, but in the shadow side. I 
ever removed the shadow 2MB superpage support code in p2m.c, and the Linux 
guest (hap=0, using shadow) can boot successful with more than 4G memory. 

Thanks!

That means I broke memory allocation when I cleaned up the tools side of
that patch. I will look into it and fix it.
