RE: [Xen-devel] Error starting xend

["Puthiyaparambil, Aravindh" <aravindh.puthiyaparambil@xxxxxxxxxx>]

Jun,

That patch did the trick. Let's hope this completes the non-NX/XD
support. I am now able to run without the rm_nx patch on the ES7000
x86_64 (with my clustered APIC kludge).

Thanks,
Aravindh
