Consult some concepts about shadow paging mechanism
Dear All:
I am pretty new to xen-devel, please correct me in the following.
Assume we have the following terms
GPT: guest page table
SPT: shadow page table
(Question a) When guest OS is running, is it always using SPT for
address translation? If it is the case, how does guest OS refer and
modify its own GPT content? It seems that there is a page table entry
in SPT for the GPT page.

shadow page code
APIs such as sh_invlpg and sh_update_cr3 take a pointer to the virtual cpu on which it needs to operate as an argument. However, it appears that the call can only operate on the currently executing vcpu.

Page tables in Xen
Hi,
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?
Thanks

[PATCH RFC v13 00/20] Introduce PVH domU support
This patch series is a reworking of a series developed by Mukesh
Rathor at Oracle. The entirety of the design and development was done
by him; I have only reworked, reorganized, and simplified things in a
way that I think makes more sense. The vast majority of the credit
for this effort therefore goes to him. This version is labelled v13
because it is based on his most recent series, v11.
