similar to: Xen 4.3 Passthrough Problems & Documentation

Aloha! Concisely, I''ve been trying for several days to get VGA/PCI passthrough working. Regarding VGA vs PCI passthrough, I''m not entirely certain of the difference? Does Xen perform a different set of operations when passing through a VGA card versus any PCIe card? I''ve read the wiki and it seems the answer is "yes;" however, when passing through a

I''m using Xen 4.3, installed from source on Ubuntu 13.04. I''ve successfully installed a Windows 8 guest, and had Xen pass it an AMD FirePro W7000 GPU (technically 2 PCI devices - the second is for the sound), as well as the virtualised graphics adapter. Windows finds the card fine, and I''ve installed AMD''s drivers. Device Manager says that the card cannot

Hi, I''m trying to get VGA passthrough to work to an XP x64 guest, and I''m seeing "interesting" things happening. I''m using the kernel and userspace tools from here: http://xen.crc.id.au/support/guides/install/# on Scientific Linux 6. I gave up on trying to get an Nvidia card to work in the guest having read about the extra patches required to get a

Hi everyone, I would like to ask what the current status of FLR, or better of FLR emulation is in latest Xen and if we can expect better support in the future. I''m asking because with xl (latest build and traditional qemu, not upstream), I always had problems with rebooting domUs which have vga cards passed through to them, because appearently they don''t get reinitialized and

Hi All- Is it possible yet to pass through a ATI or Nvidia GPU as the primary VGA card to a Win 7/8 VM, and have it fully functional there (DXVA etc), without crashing the guest or the host during operation or when resetting the guest? For hardware I have an E3 v2 Xeon, Tyan S5512 board, and an ATI 7750. Thanks! David _______________________________________________ Xen-users mailing list

Is there anyone actually using VT-d for GPU cards? From what I understand NVidia is impossible, but AMD does work for some cards. I would appreciate any hints from people that are actively using this technology. -- Simon Toth

Add commands to automatically prep devices for pass-through The current method for passing through devices requires users to either modify cryptic Linux boot parameters and reboot, or do a lot of manual reads and writes into sysfs nodes. This set of patches introduces commands to make this easier. It expands on the concept of "assignable" (from the list_assignable_devices command).

Dear Gordan, I have a Gigabyte Geforce GTX 560. Is it possible to mod it into a Quadro? If it is possible, please give me the link with the list of steps to mod it into a Quadro. Is it a simple process? Thank you very much. -- Yours sincerely, Singapore Citizen Mr. Teo En Ming (Zhang Enming)

Hi everyone, after following in the footsteps of the following discussion (http://lists.xenproject.org/archives/html/xen-users/2013-09/msg00106.html) I had been able to turn my GTX 480 into a Quadro 6000. When I VT-d passthrough it to a Debian jessie VM it shows up fine and CUDA 5.5 seems to function properly up to a point: lspci -v: 00:04.0 VGA compatible controller: NVIDIA Corporation GF100GL

I just wanted to drop a note to say that I have managed to get VGA passthrough working with multiple cards and domUs. The cards I am using are quasi Quadro 5000 (modified GTX470) and quasi Quadro 6000 (modified GTX480). (Here is an older article about modified GTS450 modified to Quadro 2000 if anyone is interested:

Hi Gordan, I received my Asus GTX 480 today (bought on ebay). Finally I succeeded in - quadrifying my GTX 480  into a Quadro 6000 ( softmod). - overpassing the 3-4GB of RAM on Windows XP 64 bits (domU) by applying a well known patch for Xen. - playing Crysis 2 and Darksiders II for a few minutes. http://img11.hostingpics.net/pics/953254ScreenshotXenSoftModedQuadro6000.png Using nvlfash I

Due to popular demand, I have finally found time to write this up. I had to rush it a little, but hopefully you get the gist. http://www.altechnative.net/2013/11/25/virtualized-gaming-nvidia-cards-part-3-how-to-modify-a-fermi-based-geforce-into-a-quadro-geforce-gts450gtx470gtx480-to-quadro-200050006000/ Any questions, please ask away, and I''ll update the article to expand on those

All, I would like to run the following issue past the list to confirm that my problem analysis makes sense or whether I missed something: We have a HP ML370G6 server with VT-x and VT-d enabled in the BIOS. It is equipped with two Smart Array HBAs - one connected to the HDD array (SmartArray P800) and one connected to an LTO tape drive (SmartArray P212). Both controllers use the same driver

Hi, My Windows 8 Enterprise HVM domU configuration is as follows. I have to *disable* gfx_passthru, that is, gfx_passthru=0.

Hi, I have a question about the bug: http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1632 This is marked as fixed in the pv-ops kernel. I am working for a company developing a xen based virtualisation solution. Unfortunately the design is tied to CentOS and there is resistance to upgrade to > 2.6.31 kernel. My question is whether it is possible for me to try to backport the fixes for

Hi Gordan, I wanted to let you know that today I decided to have a try for my GTX 680. Gigabite GTX 680 2048 MB GDDR5. I know that this particular card could be hard-moded to GRID K2 so VGA passthrough could work. Following instructions found on http://www.eevblog.com/forum/chat/hacking-nvidia-cards-into-their-professional-counterparts/420/ I just removed two resistors. Here is a screenshot

Hello, I''ve successfully passed a unmodified GTX 760 to Win7 x64. It involved some driver patching on the client side but I''m close to getting the required steps on the server side, too. Are there any legal issues that might arise from releasing a patch? Bob [image: Inline image 1] _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org
