similar to: Duplicate IRQ problem with PCI Passthrough

Florian, I read already here and there that you shall not use shared interrupts in different PV DomUs, although I never found a written statement. But behaviour is exactly as you described, thus I took care that cards that share an IRQ are in the same DomU/Dom0. I also selected my motherboards accordingly. When I lately discussed lately with someone about MSI, I had the hope this could help,

I am having trouble getting PCI Passthrough to work from Dom0 running CentOS 7 to DomU runnning Debian 8 I am using Xen 4.6 with CentOS kernel 3.18.34-20.el7.x86_64 on a Dell Poweredge T430. I think I have set it all up correctly, but I see no message when putting a USB device into any of the USB slots on the DomU There are three other DomUs running, but I have no need of PCI Passthrough set up

-----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. -

Hi All, I have configured a domU (netdom) to connect direct to a NIC using PCI passthrough. The NIC is now hidden from dom0, and hence dom0 goes off the network. Is there any way to configure dom0 to connect to the network via netdom. How do I setup a backend driver in netdom and frontend driver in dom0 and other domUs for connecting to the network? I have only one NIC on my host, and I am using

Yes, you can put the 'Tested-by' from me, I'm perfectly fine with that. Thank you for your help!

Hi there, I''m running Xen 3.2.1-rc1-pre on a Ubuntu 8.0.4 server (kernel 2.6.24-19-xen). I have some network cards which are passed through to the DomUs. ''Normally'' everything works quite well. but sometimes when a DomU crashes or has to be shutdown, the pci interrupt of that DomU gets disabled in Dom0. After that happend there is no way (at least I haven''t

Hello, I''m seeing problems with Xen and IRQ-sharing PCI cards which are passed through to a Xen DomU. As I''m not sure whether this is a problem with Xen or with the Debian Xen Kernel (2.6.26-13 from lenny) I''m using, I''d like to ask here before posting a bug. Reproducing the problem goes as follows: 1. Put a PCI card in the machine and make sure it shares

Hi, I really need help. I spent 2 days already on this pci passthrough thing. I''m using Xen 3.2.1 with Centos 5.2 64 bits on intel VT. I''d like to use PCI passthrough and I don''t think I need VT-D functionality. I''m trying to pass PCI 12:01.0 to my domU guest. I got this error when I use "xm create /etc/xen/hvm_centos_2.cfg" Using config file

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:

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

Hi, sure I can give you some info, but unfortunately as explained here (http://lists.xen.org/archives/html/xen-users/2012-06/msg00392.html), dual vga is broken for me currently, too. But i guess this is only a matter of finding the currupted changeset. In general, I was never aware that this is even a problem. I used to simply hide both graphic cards from the dom0 at boot time via the

Hi Keir, Some device have I/O space but no mem space so checking iomem to grant privileges to DomUs is not enough. Please apply this fix to unstable and xen-3.3-testing.

Xen developers, After an upgrade of my Debian Jessie dom0 and domUs, my passthroughed NIC stopped working. This bug was probably introduced in Debian Jessie sometime between 2015-12-30 and 2016-01-08 as 2015-12-30 as 2015-12-30 was the last time I upgraded without any problems according to my dpkg.log. This bug has also been reported to Debian Bug (https://bugs.debian.org/810379), where I got

Hi, i have an old proliant dl380 server, running hardened gentoo as Dom0 on Xen 4.2, with several DomUs, also running hardened gentoo.
