Hi there, In my project, I have to allocate a memory page inside the guest OS from the Xen hypervisor. The alloc_domheap_page(d) function allocates a single page from the dom heap, which looks okey for my purpose. But, I do not know how to add the allocated page into the guest page table, so that guest can access this page. I do not want to allocate a Xen page and share it with the guest. My question is: how do I make my guest OS aware of this page without doing anything inside the guest OS. Is there any function in Xen that directly adds a page into the guest OS address space or I have to walk on the guest page tables and add this page manually. Any help would be appreciated?
