RE: [Xen-devel] PAE mode mismatch in Xen (xen=no Dom0=yes)

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

Try doing a “make uninstall; make XEN_TARGET_X86_APE=y world”. If you still get the errors… like Anthony said, please do share J

 

With PAE I think you are limited to 16GB of memory if I am not mistaken. Are you on an i386 box or x86_64 box? If it is an x86_64 box then that might be the better option as you can see all 32GB.
