OK I've got a progress, but need little more help.
The thing is, X requires MTRR support:-
(please see the log below)
I activated the MTRR support part at arch/xen/i386/Kconfig
and recompile the dom0 kernel so CONFIG_MTRR=y should be
built-in.
(install/boot/config-2.6.7-xen0 does have the line CONFIG_MTRR=y).
But /proc/mtrr does not appear after reboot.
How can I activate MTRR support under ARCH=xen?
Thanks very much for your patience.
