similar to: Primary VGA Passthrough Status

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

Gordan & David, Read about your latest work, and was thrilled to learn that both soft and hard mods are working. I bought the GTX 670 model in David''s article, I will be giving this a shot in a week. I was hoping to ask a few questions. 1. Is there a specific qemu version required (traditional or the new default)? 2. What (if anything) should be done after removing the resistors

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

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)

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

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:

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

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

Hi, My Windows 8 Enterprise HVM domU configuration is as follows. I have to *disable* gfx_passthru, that is, gfx_passthru=0. Please take note. # XL domain configuration file for Windows 8 64-bit English HVM domU # Please refer to "man xl.cfg" for further explanations. # See also docs/misc/xl-network-configuration.markdown and # docs/misc/xl-disk-configuration.txt # Written by Teo En

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

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

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

The hypervisor side changes for XSA-46 require the tool stack to now always map the guest pIRQ before granting access permission to the underlying host IRQ (GSI). This in particular requires that pciif.py no longer can skip this step (assuming qemu would do it) for HVM guests. This in turn exposes, however, an inconsistency between xend and qemu: The former wants to always establish 1:1 mappings

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

I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU passthrough without crashes. Unfortunately, the same crashes still happen. Massive frame buffer corruption on domU before it locks up solid. It seems the PCI memory stomp is still happening. I am using qemu-dm, as I did on Xen 4.2.x. So whatever fix for this went into 4.3.0 didn''t fix it for me. Passing less than 2GB

I believe both mailing lists are great but there are so may postings that many issues get missed. There are some bugs that hand never been resolved because developers are unaware of it.
