Hi all, I''ve got a couple of questions regarding the current status of nvidia with Xen, since it is well known that nvidia doesn''t work as smooth at the moment with Xen (comparing to ati). My current goal is to use one nvidia gtx460 card and the onboard intel hd4000 on dom0, and then do passthrough for another nvidia gtx460 to a Windows domU. I know there are patches

...; Moreover, there is problem with the open source driver ''nouveau'' for > NVIDIA card (also has something to do with PAT layout of XEN) which > causes memory corruption. Huh? Can you point me to a bugzilla please? There was a corruption issue where you can pass in ''nopat'' on the command line. > > I found several patches for XEN which supposedly provide basic MTRR > support for XEN however there is still no /proc/mtrr. Jeremy, can you > tell me if you had been able to get /proc/mtrr on XEN dom0? > > Thanks for your time. > > Dam...

I have tried 4 time unsuccessfully to install Xen 4 on Ubuntu Lucid (10.4) 64 bit version using the tutorial at http://bderzhavets.wordpress.com/2010/04/24/set-up-ubuntu-10-04-server-pv-domu-at-xen-4-0-dom0-pvops-2-6-32-10-kernel-dom0-on-top-of-ubuntu-10-04-server/ on a Lenovo thinkcentre workstation.

Hello, I''m building a dom0 system from sources and facing a problem with the xorg server. I''ve successfully compiled and booted a dom0 with xen 4.1.2. Everything works fine and Im able to start an HVM Windows domain. Now comes the problem: the Xorg server using either vesa or fbdev driver can''t start: - when using the vesa driver it just fails with error messages (see

I can get a basic X environment (Vesa driver) when running in non-Xen mode but, when booting into the hypervisor, that fails. I've tried one suggestion, adding a nopat to the kernel invocation, but that hasn't helpd although I'm sure the full suggestion, which I can no longer find, also mentioned an "mtrr" addition as well. I'm also sure believe I even saw someone get pointed to some "aftermarket" xorg-x11 RPMs that claimed to wor...

The function that returns ENOMEM is actually copy_mm. It returns ENOMEM when dup_mm returns 0. copy_mm receives clone_flags and task_struct * tsk. I think tsk is pointing to the new task (the process being forked). copy_mm assigns some values into *tsk, then: tsk->mm = NULL; tsk->active_mm = NULL; then we check if current process has ->mm; if not, return 0 (effectively

Hi, I recently compiled a Xen-4.0.1 and pv-ops Dom0 2.6.32.27 kernel from JF''s tree.Where my hypervisor could not boot and unfortunately the system is rebooting so frequently that I am not able to note down the error messages on a paper and pencil.So now I am planning to go for a non pv-ops Dom0.I am not clear as what should be the approach? I have been Googling it every now and then and

At least until we get the a) moving or alternative solutions are found. c). Use the ''nopat'' argument on the Linux command line (which is what this patch set (b) forces unconditionally) and has been recommended on the BZs for users.

Hi, Following is a simple patch that is needed in nouveau to get accelerated X on a Xen dom0 pv_ops kernel. The kernel is jeremy's 2.6.31.6 as of 20100222. The whole gpu tree of nouveau (which is almost the mainline merge), was substituted into the kernel-tree. All components of X (mesa, Xorg-server-7.5, xf86-nouveau, libdrm) used of the same day.
