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

Hello guys, this drives me insane. I am trying to pass romfile of my GPU for UEFI boot This is an error I am getting : [root@brutus-coreos opt]# virsh start winos1 error: Failed to start domain winos1 error: internal error: early end of file from monitor: possible problem: 2016-02-07T16:56:09.358285Z qemu-system-x86_64: -device

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

I''ve been trying to set up a VGA-passthrough on my Ubuntu 12.04 box to run Windows (for gaming) while leaving my RAID-5 array available (managed by Linux). First, here are the machine specs: CPU: AMD A8-3870K 3.4GHz Quad-Core APU GPU: APU-integrated AMD Radeon 6550 (shared memory) Mobo: ASUS F1A75-V EVO with AMD-virtualization enabled in UEFI-BIOS RAM: 8GB DDR3 1866 G-Skill Sniper

Hi I need the e820_host option for a passthrough of an digitaldevices dvb-s2 card. Without this I'cant initialize the card in the domU. On an all my domU's with high IO load like an file server I need to set max_grant_frames = 64 or higher. Without this I get a lot of messages on dom0/domU and kernel exceptions. I've read it should be ok to set it = 256 on all domU'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, for us GPU Passthrough Customers there is one thing left for total happiness (at least for me): Working Upstream QEMU - simply because it brings a sound device which hast working x64 drivers (intel-hda). Afaik Upstream QEMU does not yet work with GPU-PCI Passthrough. I have to admit i haven''t tried it, but perhaps Anthony (or others) could clarify what''s missing in

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, I am currently considering to upgrade my Ubuntu Hardy Dom0 from Xen 3.2 to 3.3, but I am a bit concerned about some of my DomUs that rely on PCI Passthrough. Are there any restrictions or problems with PCI Passthrough in Xen 3.3, anything I have to look out for, especially with the Hardy Dom0 kernel in mind? Thanks, Paul. -

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

Four of them are on one quad giga ethernet device. If I manually unbind the devices and allow qemu to use them, with intel IOMMU working, everything works like a charm. Here's how I do it manually: >

Hello, I have been struggling as of late to successfully configure a pci passthrough using libvirt with kvm. Hoping someone can shed some light on the problem. Overall my experience with virtualization limited is so please forgive. The guest runs fine till passthrough is configured. I am using virt-manager. This has been tried on both a Fedora17 x86_64 and Arch Linux x86_64 build with pretty much

Hi everybody! On a Centos 5.8 with libvirt qemu-0.10.5-1.el5.2, libvirt-0.8.2-22.el5 and 2.6.18-308.11.1.el5 I have a Windows machine that used to have pci-passthrough for a device enabled and working. After an update (kernel, libvirt afaik) and a reboot, pci-passthrough stopped working. Intel IOMMU is enabled (can see that from the dmesg output). All i get on the console when i try to start

Dear Michael, Did you activate the Intel IO MMU (or its equivalent for AMD)? Also, did you load the pci_stub module for Linux? It is mandatory (it will replace current driver for your passed through hardware).

Hi Alex, The first bit of advice that I was about to give was that you should have a look at a particular thread on the Arch Linux user forum. But as it turns out, the article that you found (which seems really well-written) already mentions that thread, and in fact even links to one of my comments on that thread, namely this comment: https://bbs.archlinux.org/viewtopic.php?pid=1313007#p1313007
