similar to: Upstream QEMU and GPU Passthrough

Hi List, many People seem to be interested in the Graphic-Card Passthrough Feature (for more or less obvious reasons). Official Support is still under development, and i hope not to interfere with it in any (bad) way ... But i remember my own painfull and timeconsuming research when i wanted this feature to work, so i thought perhaps this spares some time for the unpatient users like me :)

I know these are mostly gamers but they have a lot of experience doing PCI pass though: https://discord.gg/du9ecG I have found them extremely helpful in the past doing libvirt PCI passthough. *Paul O'Rorke* On 2020-02-05 10:13 a.m., Jim Fehlig wrote: > On 2/4/20 1:04 AM, Christoph wrote: >> this config does not work... why? > > Without more details, I don't know why

I have been trying to setup GPU passthrough for a couple of days now with little luck. I''m hoping someone can shed some light as to where I may be going wrong or at least identify some genuine bugs. Essentially pci passthrough works for me but gpu passthrough doesn''t. My system is currently configured as follows (please ask if you need further details) Asrock Z77 e-Itx

I have a Radeon HD 6670 GPU and an IOMMU enabled motherboard. With that GPU and motherboard, I had absolutely no trouble getting GPU passthrough to work with XCP 1.6 and a Windows 7 guest. It just worked! And after some trial and error (mostly error), I was able to get GPU passthrough working with XCP 1.6 and an Ubuntu 12.04 HVM guest. But with Ubuntu 12.10 and 13.04 HVM guests, I have had

WinXP ignores a USB passthrough! Hello, I need a persistent passthrough of a USB-device: Bus 001 Device 020: ID 04e6:5311 SCM Microsystems, Inc. I added <hostdev mode='subsy.... </hostdev> like this to xml file: [...] <on_crash>restart</on_crash> <devices> <hostdev mode='subsystem' type='usb' managed='no'>

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

Is support for passing through an AMD GPU as the primary graphics device present in the main Xen 4.2 development tree, or does it require additional patches? Also, are any of the optional VT-d features (such as interrupt remapping) required for GPU passthrough? I am wanting to run Xen with graphics passthrough on a system with a Core i5-660 processor (which lacks some of the optional

I'm looking for assistance with pci-passthrough on CentOS 6.2. I've installed libvirt version: 0.9.4, package: 23.el6_2.8 from yum. I have a windows XP client setup via virt-manager which boots and runs fine until I attempt to assign a PCI device to it. The error log reads: -----------------/var/log/libvirt/qemu/SageTv.log---------------- 2012-06-02 22:55:07.801: starting up LC_ALL=C

Hi All, it is possible to use pci/gpu passthrough with xen and libvirt? If yes, how is the syntax? Can I get an example? -- ------ Greetz

I'm sure this is obvious to many, but I've had to do some research. The best TL;DR summary I've found is Keith's original commit 185a383ada2e adding the controller to Linux. If there's

Hello guys, I have a problem when using my MSI R9 380 4G graphic card as GPU passthrough with KVM. At the first linux boot (Fedora 23) I am able to successfully start virtual machine and it works! However if i will shut down virtual machine and start it again - the screen will stay blank! So far I have been able to find on the internet that some graphic cards just can not reinitialize itself

Hello, [please CC me] Recently I have reported a Debian bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=703430 Possible memory leak in qemu-dm when Xen USB Passthrough is used I wonder if somebody encountered such behaviour or how can I debug it farther ? Best Regards, T

Hi, I saw there was an active discussion about pci passthrough support in KVM. I'm not a Dev, only a sys admin that need this support. As i saw on the KVM home page that this feature is plan for 2H2008 in the roadmap, I wondered if you already have a more precise time frame for this release? Xen already have this feature but for the rest i prfer KVM. As this is a key point for the final
