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 M...

Hi, How come gfx_passthru is now an invalid option? Does it mean Xen-unstable 4.4 changeset 27214 no longer supports vga passthrough? -- Yours sincerely, Singapore Citizen Mr. Teo En Ming (Zhang Enming)

Hi, I''m trying to pass an intel video card to a guest via VT-D. I got this to work once so i know my system can do it, but I can''t seem to replicate my success. Not sure if something changed in the bios(vt-d is still enabled there), or elsewhere. When I pass a device with gfx_passthru=0 (using config below), guest boots up and the vid card shows up at an incorrect pci id(ie not 00:02.0). Things work as expected. When I set gfx_passthru=1, the monitor goes blank, and after 12 seconds of execution, I get a vague ''Error: Device model isn''t ready for commands'...

Pass gfx_passthru parameter to QEMU. Keep it boolean for now as QEMU does not expect any other integer value. Signed-off-by: Allen Kay <allen.m.kay@intel.com> _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, to use the host keyboard and touchpad of my laptop while running a HVM guest with passthroughed primary gfx-card I wrote a simple emulation. To activate it change gfx_passthru=1 -> gfx_passthru=1001 in the domU config file. This was done this way to have a small footprint. Also the embedding in helper2.c is a little bit awkward. Another problem using this way is that the VT in dom0 is not reset when the domU gets destroyed. I wrote this as a workaround until the annou...

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

The OpRegion shouldn''t be mapped 1:1 because the address in the host can''t be used in the guest directly. This patch traps read and write access to the opregion of the Intel GPU config space (offset 0xfc). To work correctly this patch needs a change in hvmloader. HVMloader will allocate 2 pages for the OpRegion and write this address on the config space of the Intel GPU. Qemu

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

I''ve been trying to pass through a GPU to a domU, so far with a lot of trouble but finally a success. PCI passthrough works, I''ve had the usb hubs work successfully. Today I tried to pass through my ATI card to an ubuntu hvm domU with no gfx_passthru and got this: [...] (XEN) memory_map:add: dom14 gfn=f3040 mfn=f7c40 nr=4 (XEN) memory_map:remove: dom14 gfn=f3040 mfn=f7c40 nr=4 (XEN) memory_map:add: dom14 gfn=f3040 mfn=f7c40 nr=4 (XEN) irq.c:270: Dom14 PCI link 0 changed 5 -> 0 (XEN) irq.c:270: Dom14 PCI link 1 changed 10 -> 0 (XEN) irq.c...

...13 Xen 4.0 Tutorial found here: http://wiki.xen.org/xenwiki/Fedora13Xen4Tutorial The tutorial was very helpful and many thanks to Pasi for putting it and the RHEL6 tutorial together. Initially I could not get VGA passthrough to work, all the VGA passthrough procedures I found included putting gfx_passthru=1 in the VM configuration file but every time I did this the boot process would hang with a prompt at the QEMU console. After several days of trying to figure this out I finally hit the magic combination... VGA passthrough worked without gfx_passthru=1 configured and the initial passthrough n...

...I'm not sure which package this problem would fall under. Ultimately decided to file with xen-utils-common with 'xl' being the frontend interface for the xen system.) It looks like VGA passthrough is currently unsupported/broken in the xen system packages or in its dependencies. With gfx_passthru=0 (default), I'm able to boot a domU and access its interface using vnc. However if I enable gfx_passthru, the domU fails to boot, and I'm greeted with an error message telling me the device model failed to spawn: libxl: error: libxl_dm.c:1371:device_model_spawn_outcome: domain 16 devi...

...tches were posted but that was long time ago so my first question is: Is passthrough of ATI devices as primary VGA supposed to work now in Xen 4.2.1 without patches? My second question is: How can i debug the problem? I can''t access domU through SSH after it''s created. When I set gfx_passthru to 0 it''s starting normally. How can I tell what went wrong? When I create domU I get this in logs: dm-command: hot insert pass-through pci dev register_real_device: Assigning real physical device 03:00.0 ... register_real_device: Disable MSI translation via per device option register_rea...

...find an audio card. If I don''t hide the pci devices, i can get some sound working on dom0, and have console working all right on it. If I try to pass the devices, I effectively have no screen left giving an output for dom0, but the domU still doesn''t show anything (tryed with gfx_passthru). I''ll be working on it until I figure there is a hardware problem, or get it to work, but it might get easier if I could get some hints of what i''m doing wrong, if it''s something obvious for one of you. If anyone is willing to help, but need more input, just tell me...

Hi all, I''m trying to give control of a radeon HD 5700M to a win 7 x64 VM. I''m running Xen 4.1.1, with a CentOS 6 dom0. If I give control of the graphics device to the VM but don''t set the gfx_passthru flag, it will boot, and when the OS comes up, it works fine and even scores 7 out of 7.9 in graphics performance. However, with the flag set, it doesn''t really boot, as far as I can tell - it sets in state ------, doesn''t take control of the additional VCPUs it''s...

...error went away. Both the virtual and physical VGA devices are listed by lspci in the Linux domU, but I cannot seem to use the physical device. I then tried to passthrough the primary adaptor. It doesn’t work and I cannot even start X11/VNC in the dom0 to inspect the domU. I have also tried adding gfx_passthru=1 to my cfg file and this prevents the domU from booting. I would appreciate any suggestions as to where to look for problems. My cfg file is: name = "Arch" builder = "hvm" kernel = "/usr/lib/xen-4.0/boot/hvmloader" device_model = "qemu-dm" on_poweroff = &...

Hello I am new in XEN and Linux. I am trying the VGA passthru. I can xen-pciback.hide EtherNet, Serial Com port. But when I xen-pciback.hide my VGA. I can no longer login to the Linux(Fedora 12). Then how can I xm create a XP DomU guest? Can anyone help? I am using Intel Q35 MB with Intel Core2 CPU. _______________________________________________ Xen-users mailing list
