Hi everyone, I would like to ask what the current status of FLR, or better of FLR emulation is in latest Xen and if we can expect better support in the future. I''m asking because with xl (latest build and traditional qemu, not upstream), I always had problems with rebooting domUs which have vga cards passed through to them, because appearently they don''t get reinitialized and

The attached patches allow the pciback module to perform a reset whenever a PCI device is: - attached to the pciback module, as so: echo "0000:01.07.0" > /sys/bus/pci/devices/pciback/bind - detached from the pciback module, as so: echo "0000:01.07.0" > /sys/bus/pci/devices/pciback/unbind - and when the guest is done with (internally when the guest is not using

Hi, all, The attached patches try to improve the current FLR logic. The idea is: removing the FLR logic from hypervisor and adding the improved logic in Control Panel. The current FLR logic in hypervisor has some issues: 1) Dstate transition is not guaranteed to properly clear the device state; 2) the current code for PCIe FLR is actually buggy: PCI_EXP_DEVSTA_TRPND doesn''t mean the

Hello XCI developers, I have a HP6930, downloaded xenclient from the git. And by following the instruction in HOWTO, I could get xenclient boot up fine. I try then to start a guest using xenvm.readme as template and nothing shows on the screen for the guest, although xenops shows 2 doms running. Can you point me to how to start a guest. And also, is the tree downloaded from git enough to arrive

Folks, The first release candidate for Xen 4.0.0 has been tagged and published. You can grab it from here: http://xenbits.xensource.com/xen-unstable.hg (tagged ''4.0.0-rc1'') Please test it! -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Aloha! Concisely, I''ve been trying for several days to get VGA/PCI passthrough working. Regarding VGA vs PCI passthrough, I''m not entirely certain of the difference? Does Xen perform a different set of operations when passing through a VGA card versus any PCIe card? I''ve read the wiki and it seems the answer is "yes;" however, when passing through a

Hello, I've been consistently attempting to make the setup mentioned in the subject work on the following hardware: Xeon E3 1275 (v1, Sandy Bridge) Asus P8B WS (Firmware: 0904 and 2009) 16 GB RAM Sapphire Radeon HD 7950 OC (Firmware: 015.013.000.010.000705) Linux 3.4.1 dom0, x86-64, pvops. Xen 4.1.2 (+ security patch) and 4.1.3-rc1. Old qemu-dm setup. (not new mainline qemu) Windows 7 64-bit

Currently we assign devices with VT-d in Xend, this raises two issues: 1) assign devices regardless of they are hidden by pciback or not. If the device is not hidden, it results in the device doesn''t work in Dom0; 2) device is assigned one by one, if assign multiple devices, some devices may have been assigned when problem happens, it results in assigned devices don''t work in

This patch maps RMRR in intel_iommu_add_device() if the device has RMRR; move domain_context_mapping() to be in front of list_move() in reassign_device_ownership(). Currently, hypervisor sets up devices and RMRR for dom0, and dom0 also adds devices for itself via hypercall. This is obviously duplicate. In order to allow old dom0 kernels to work with iommu-capable platforms, maybe it cannot be

Hi, I''m trying to get VGA passthrough to work to an XP x64 guest, and I''m seeing "interesting" things happening. I''m using the kernel and userspace tools from here: http://xen.crc.id.au/support/guides/install/# on Scientific Linux 6. I gave up on trying to get an Nvidia card to work in the guest having read about the extra patches required to get a

I''m currently working on moving storage services into their own domain and I''ve been looking at blktap2. I''ve been trying to get an image mounted with blktap2 and for some odd reason and tapdisk2 keeps hanging instead of quitting at the end. I haven''t removed any of the storage startup code at this point so everything should be as it normally is in xen-unstable.

I was reading the Wiki page here: http://wiki.xen.org/wiki/VTd_HowTo don''t know how updated it is, BUT at the top it said: -------------------- -------------------- -------------------- -------------------- -------------------- -------------------- _Xen 4.1 xl tools notes _ * Only devices with FLR capabilities are supported. * Passing through a PCI card without FLR capability

Hi there, I have a question regarding PCI passthrough on the Citrix XenServer 5.6 (Xen 3.4.2). I already managed to get some soundcard passed through to a Windows guest. So I think my knowledge about that topic isn''t _that_ low. But I cannot seem to pass through a SATA/PATA controller to a Linux guest. I have some additional CD/DVD burner (PATA) attached to a SATA/PATA controller

Hi all!. First of all sorry about my English it''s not very fluid. I have a small server based upon Supermicro X7DBN (Chipset Intel® 5000P) motherboard and Intel Xeon E5320 (1,83Ghz) with 4Gb of FB-DIMM RAM. The OS is Debian Lenny in dom0 (2.6.26-2-xen-amd64) and Debian Lenny in domU (2.6.26-2-xen-amd64). Xen is 3.4.2 compiled from sources. The problem comes when I need to passthrough

I have successfully passed through a video card, network card, USB mouse, and USB keyboard to a MS Vista guest. That works well. I am trying to add another PCI device, such as a audio card or PCI USB hub, but I am running into a strange problem. When I plug the PCI audio (or USB card) to the motherboard. It makes it so that the PCI video card is no longer an "assignable device" (xm

Hi, everyone. I''m Guilherme Suzuki (brazillian, by the way) and really interested in xen-vga-passthru. Lately, I bought a brand new Saphire HD 7950 (OC Boost) because I saw in a wiki somewhere that users have been able to passthru these VGA devices to domU (win7, win-xp and so on). But, after I installed it, I executed *lspci -vv* to check if FLR in DevCap was present (which

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 nothing...

Thanks Anna, this was also quite interesting for me. Did you mean that I just have to eliminate the else branch or raise arround "All devices behind the uppermost PCI/PCI-X bridge must be co-assigned to the same guest." or do I have to eliminate more in order to prevent an FLR (whatever that is). For my board it''s definitely necessary to move PCI devices in different guests,
