Hi,

I want to read the code about the implementation of writable page table. But
I can't find it in the source codes.

I assume that when a guest OS allocate a page table (e.g. when create a
process), it will tell hypervisor the address of the page table, then xen
will set permissions on that page to trap the writes from the guest OS. But
I can't find such code.

Thanks,
Weiming
