I have a question about memory page tables in Xen. As far as I
understood, every modification
to page table will go through Xen(hypervisor). Is it so that all page
tables are actually allocated
in Xen(hypervisor) instead of guest OS(domain)? Also, is it the case
that Xen(hypervisor) needs to
maintain a page table for each process running in every domain?
