Hi,
I'm working on save/restore for domains using translated shadow page
tables. I've added support so that page tables are not
(un)canonicalized during save/restore, but when the new context is
being loaded, the set_gdt call is failing. Specifically, the
get_page_and_type() call fails.
Any ideas on what would cause this error? It's not clear to me what
part of the normal restore code sets page types so that this call
usually works.
The basic steps of my restore routine are:
-read in pages
-enable shadow mode
-add grant tables to physmap
-clear events/copy shared info frame
-set vcpu context (this step fails)
Thanks for any pointers,
-Tim
