After upgrading from xen 3.2.x to xen 3.3.0 I get an error message when using pci passthrough with pv guests (my system is not vt-d enabled): xm create -c /etc/xen/domU/myguest Using config file "/etc/xen/domU/myguest". Error: pci: 0000:0e:05.0 must be co-assigned to the same guest with 0000:0f:0a.0 Sharing diffrent pci devices behind a pci bridge used to work in older xen versi...

Dear All, I have tried to apply VGA passthrough patches hosted at Jean David Techer''s website to Xen 4.3-unstable. However, I cannot get VGA passthrough to work with Xen 4.3-unstable. Are the VGA passthrough patches hosted at David Techer''s website incompatible with Xen 4.3-unstable? This is David Techer''s website:...

This bug, at its core, is that currently there is no supported solution for VGA passthrough on Xen for stable version Jessie from Debian. After browsing Xen's repositories, I found out that Xen did not claim to support VGA passthrough with the upstream qemu-xen device model until Sep 25, 2015, the date the xl.cfg man page was updated to indicate support for VGA passthrough with ups...

Is there any information available when one can expect OpenSolaris to handle PCI Passthrough als Dom0? This thread: http://opensolaris.org/jive/thread.jspa?threadID=45875&tstart=135 makes me think there might be some work going on... Thanks Ares

_History_ I have 100% success in Xen VGA Passthrough with Xen 3.5-unstable with my first Palit NVIDIA Geforce 8400 GS VGA card in 2009, which is 3 years ago. Then my first Palit NVIDIA Geforce 8400 GS VGA card overheated and malfunctioned. So I bought a 2nd Palit NVIDIA Geforce 8400 GS VGA card several months ago in March 2012 for S$44, to replac...

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: http://www.altechnative.net/2013/06/23/nvidia-cards-geforc...

Another bundle of issues from Coverity triage. The first one is in x86/mm, and looks scarier than it is. The others are all in xen/drivers and AFAICT are pretty minor. Cheers, Tim.

Hi all I''m trying to enable VGA passthrough in linux domU without success. I want to pass through AMD Radeon HD 4850 - 03:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV770 [Radeon HD 4850] as a _primary_ VGA for the VM.

Hi Xenners, I have tried to upgrade to kernel 3.5 and experienced the USB/PCI passthrough problem. This has not been "fixed" in 3.6 either. I do not know if this is qemu, xen or kernel related. I am using Xen 4.2 final and Xen 4.3-unstable to test. DomU is Windows 7 64 bit or Linux Fedora 17. In Windows, I get the little yellow triangle with Code 10 (I know this means not...

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)

Greetings - I saw Andrew Holway's post yesterday referencing using PCI passthrough as a solution to someone else's issue. Not being familiar with it, the post made me look into it more to see if it is something to use for my setup. From my research on the web, I have two questions to make sure I understand how PCI passthrough works. 1. If you use PCI passthrough on a...
