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 versions for

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

Hello, I am looking into building a workstation using Xen to host several operating systems. Looking at the pci passthrough requirements of Xen4.1 on the VTdHowTo<http://wiki.xensource.com/xenwiki/VTdHowTo>page, I am a little puzzled with the fact that only Intel Core2Duo (with VT-x), Core2Quad, i7 and Core i5 (vPro Brand) CPU''s are supported while motherboards with the i55x0

Hi Jeff. I read that you use PCI Passthrough and works well, i was wonder if you can tell me how you do that ''cause i can''t find how to do it :( and i really need to. So if you can give some advice about how you do it would be really helpful. I appreciate your help Jeff.

Hey everyone, I realize that people asking about PCI passthrough has been thoroughly beaten to death many a time, however I couldn''t find the answer to these questions anywhere (and I''d really like to know :P) so please just bare with me. I know the GART built into AMD chipsets can act as a "mini IOMMU" and do DMA translation but not protection/isolation. However,

Hi folks, Has anyone encountered the following PCI passthrough error? error: internal error Process exited while reading console \ log output: char device redirected to /dev/pts/1 assigned_dev_pci_read: pread failed, ret = 0 errno = 2 It's produced after I've detached the PCI device from the base OS and have tried to start up the guest domain. To get to this point, I

I'm trying to pass-through my VGA card to a guest session. I found: http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM - which is very frustrating because there's no date on the documentation. I suspect it's old. It does clearly say that you must have VT-d support for pci pass-through. It then goes on to say "Some work towards allowing this ["software

I hope someone can enlighten me. I have a quad-port Intel 82580 nic (igb driver) on my system and I''d like to dedicate each nic to a HVM via VT-d PCI passthrough. The IOMMU on my system seems to work, I can assign the PCI devices to my HVMs. The HVMs see the pci device and load their respective igb drivers, and ethtool -i eth0 works on each HVM, shows the drivers are loaded and the

Further to my messages back in May I have at last got round to trying to get my DomU to recognise USB devices. I am using Xen 4.6 with CentOS kernel 3.18.34-20.el7.x86_64. I have to manually make the port available before creating the DomU by issuing the command: xl pci-assignable-add 00:1a.0 otherwise nothing shows in: xl pci-assignable-list I have added this to my .cfg file as per the

Hi All, Please help me. I am now installing the XEN on my PC and trying to config the pci pass through. My motherboard is intel DQ45CB which is vtd enabled. I downloaded the latest xen4.0 source from xen.org which is the latest release. I downloaded stable-2.6.32-x dom0 kernel source from jeremy''s repository. After compiling the xen and dom0 kernel, I could play it. I could create

All, I would like to run the following issue past the list to confirm that my problem analysis makes sense or whether I missed something: We have a HP ML370G6 server with VT-x and VT-d enabled in the BIOS. It is equipped with two Smart Array HBAs - one connected to the HDD array (SmartArray P800) and one connected to an LTO tape drive (SmartArray P212). Both controllers use the same driver

Hi, I want to perform pass through I/O from my domU. I guess I would need an additional network card for the same. Is there any preference on the second network card I should get or any one is fine? I have a x86_64 machine with Cent OS 4.4 running. Are there any additional considerations that I cannot see - Kindly let me know. Thanks, Asim _______________________________________________

int.patch: - Supports only level-triggered interrupts. Edge interrupts support will be added shortly (should be fairly simple) - Change polarity trick: in order to reflect the external device''s assertion state, the ioapic pin gets its polarity changed whenever an interrupt occur. So an interrupt is generated when the _external_ line is asserted (then,

Hi all! I''m hoping someone here might be able to help. I''m familiar with several UNIX''es, though farily new to Linux... I''m running RHEL 5.2. I''ve got the RHEL kernel headers installed, etc, and compiled xen-3.3. Once that was built, I rebuilt libvirt, etc, the kernel, and all the modules. The whole mess boots and runs fine... mostly. My hardware

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
