I am trying to export a memory page of dom0 to a domU in readonly mode. In dom0, I grant access permission to that domU. In domU, I did
HYPERVISOR_grant_table_op(GNTTABOP_map_grant_ref, map, res->nr_pages);
All these functions returned successfully. But when I tried to access data in the mapped memory page, all data I got is 0. Is there any restriction that preventing dom0 pages from being export to other domains? If so, is there any way to relax this restriction?
No, there are no such restrictions.
