Hello everybody,

I have to work with the Xen 4.2 memory management code for a research
project and I have some questions.

1) Since I have to change and/or remove some entries in the hypervisor
   page table, I would like to know the "virtual address" of the CR3

2) I would also like to know if the VMCS virtual address is mapped inside the
   page table pointed by the HOST_CR3.

3) Are there functions to perform the page walking on the hypervisor
   page tables?

Thank you for the attention,

Best Regards.
