Just recompile the xen hypervisor with PAE support, and you should be good to go. Not 100% sure here, but " make clean ; make XEN_TARGET_X86_PAE=y " should do the trick. If you don''t need that much RAM, you also could recompile your kernels without PAE (the option is named HIGHMEM_something in menuconfig). /Ernst _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Did you use "make XEN_TARGET_X86_PAE=y world" to do the build?

Hi I actually found the answer myself before reading the replies, I edited the Config.mk files by hand and changed it from ?=n to ?=y. then make clean && make install && make dist and when I rebooted it worked.
