hello, I would like to map (Read/Write) pages owned by a HVM guest from my Dom0 Linux kernel module. I have access to the "machine frame numbers" of these pages. 1. What is the right interface to do this? kmap needs ''struct page'' ptrs which I doubt exist for pages owned by a HVM guest. Is there a hypercall to do this then? 2. Do I need to modify the HVM behavior in

Hi, Maybe it''s a dumb question, but I''m actually trying to understand how the memory allocation works within Xen. I try to give 128MB to a domU and see if it increases for example when I "nano" a 500mb file, but the process just get killed when it reachs the 128MB memory limit. How do I configure the guests so they can ask for more memory until a limit is reached

hi I try to understand the code of xen memory there are gmfn, gpfn and pfn in the xen and in the /xen/include/xen/mm.h there are some explanation about them as follows: * 1. gpfn/gpaddr: A guest-specific pseudo-physical frame number or address. * 2. gmfn/gmaddr: A machine address from the p.o.v. of a particular guest. * 3. mfn/maddr: A real machine...

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. (Question

This patch allows core-dumping to work on a cross-bit host/guest configuration, whereas previously that was not supported. It supports both PV and FV guests. The core file format generated by the host, needs to match that of the guest, so an alignment issue is addressed, along with the p2m frame list handling being done according to the guest size.

Hello XCI developers, I have a HP6930, downloaded xenclient from the git. And by following the instruction in HOWTO, I could get xenclient boot up fine. I try then to start a guest using xenvm.readme as template and nothing shows on the screen for the guest, although xenops shows 2 doms running. Can you point me to how to start a guest. And also, is the tree downloaded from git enough to arrive

Hi I need to use hypercalls from HVM domain (e.g. HYPERVISOR_add_to_physmap). However, it does not work when I am trying to invoke it from HVM Linux guest. Basically, I don''t see that anything happens on hypervisor''s side. I also grep''ed the guest code for ''vmmcall''/''vmcall'' and did not find anything. Is it possible to do it at all?
