Hi,<br><br>I want to read the code about the implementation of writable page table. But I can&#39;t find it in the source codes.<br><br>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&#39;t find such code.<br>
<br>Thanks,<br>Weiming<br><br><br>
