Dear George Dunlap,
I just need to enable the Xen shadow page table ( if HAP is not possible) in that I need to take the control of dom0's pages in order to modify their control flags. is there any solution for this problem.
it's noticeable that, I have enabled this feature by directly setting of the opt_dom0_shadow
init variable but I cause some CPU stall.
thanks in advance. Regards

Dear friends,
I'm working on Xen's Dom0, my question is how we can enable the shadow page table or hardware assistant page table for it (the Dom0). Thanks in advance.

You can't enable HAP at the moment. What do you want to do with shadow pagetables?
