hi,

It looks like xenlinux 2.6 now uses writable page tables by default (I can't find the switch to enable/disable them).

I need to track writes to page tables, and I was wondering if it is possible to get a page fault upon writes to read-only mapped page tables, as when writing to other read-only mappings?

Thanks,
Jacob
