Hi, My base system is Gentoo x64, and I compiled my kernel with Xen paravirtualization support. The kernel can boot without any problem in native mode. But when boot in Xen mode, I cannot start the xenstored service. This is my grub config file: title Gentoo x64 kernel-3.2.11-gentoo root (hd0,2) kernel /boot/kernel-3.2.11-gentoo root=UUID=38213e99-588e-4a7d-a215-8835f7afb1c4\

Hi, I followed this guide<http://wiki.kartbuilding.net/index.php/Xen_Networking#Routed_Networking_with_NAT_2>, and started my xend service with nat-network support: (network-script network-nat) (vif-script vif-nat) Then I started my domU with the following vif configure: vif = [''ip=10.0.0.1'' ] my domU is a win7 system, and I configured the network as: ip:

Hi, I have successfully start my Win7 x86 domU on my x64 Xen dom0 system. Now I want to give my Win7 full access to my Nvidia card. lspci 01:00.0 VGA compatible controller: NVIDIA Corporation G86 [Quadro NVS 140M] (rev a1) and I added these to my /etc/modprobe.d/xen-pciback.conf options xen-pciback hide=(0000:01:00.0) then I ran modprobe xen-pciback nothing happens on the screen, and my

Alex, I'm trying to think through how binding/unbinding of devices will work with VFIO for platform devices and have a couple of questions about how vfio-pci works. When you bind a device to vfio-pci, e.g.: # echo 1102 0002 > /sys/bus/pci/drivers/vfio-pci/new_id ...I understand that the echo into 'new_id' tells the vfio pci driver that it now handles the specified PCI ID. But

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.

Hi, I boot my Gentoo dom0 using grub2 + UEFI. The system can boot and works fine. But I cannot see "/sys/firmware/efi", and "modprobe efivars" gives me error. I am thinking maybe I should use the xen.efi to boot my system. But I have not succeeded in doing so. Please point me to the right direction.

Hi all I have a very weird case of pci passthrough. I have a machine with 7 network interfaces, all of them intel. 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: root@kybrat (x86_64) ~]$ lspci -nn | grep net 00:19.0 Ethernet controller

Hi! As dom0 I''m running Ubuntu Hardy withe xen 3.3 from backports. Reason to using xen 3.3 is that I could get Intrepid stock kernel to work as domu with xen 3.2. Now the problem I have is that I can''t passthrough PCI-devices to my domu. If I run lspci in the domu nothing is returned. I''ve tried to use the kernel from Hardy (2.6.24-21-xen) and stock kernel from

Hi there, After updating a server from CentOS 5.3 to 5.4 my Xen pci-passthru setup has some troubles. The server has two NICs, one used by dom0 and the other assigned to a domU and one SCSI controler assigned to another domU. It has been working fine since CentOS 5.1, when I did the initial setup. After upgrading to 5.4, I get this error when starting the domU with one of the NICs assigned:

Greetings! I am trying to do a hot driver swap between the vfio-pci and nouveau drivers for my secondary Nvidia graphics card. I boot up with vfio-pci enabled. With this script I give control over the GPU to nouveau: echo "0000:01:00.0" > /sys/bus/pci/devices/0000\:01\:00.0/driver/unbind echo 0x10de 0x11c6 > /sys/bus/pci/drivers/nouveau/new_id echo 1 > /sys/bus/pci/rescan

Hi, I am having great difficulties in getting pci passthrough with VTd to work, surely I am doing something stupid but I cannot see what. "tangram" (https://www.blogger.com/profile/06588030231546523539) has been a huge help, but despite his efforts I am still stuck. Hardware: Intel S3200SHV motherboard BIOS : S3200X38.86B.00.00.0052 CPU : Intel Core 2

Trying to set up PCI pass through with xen 3.2.1 on Debian Lenny, with xen Kernel 2.6.26... having no luck. I have the following configured... i) Virtualization and vt-d are both enabled in the bios, I have power cycled after making these changes. ii) I have these option in grub menu; iommu=1 pciback.permissive pciback.hide=(07:01.0)(01:00.0) vtd=1 iii) I have this in my cfg file

Hi, I have a PC with 3 ethernet interfaces. I am trying to a) assign 2 ethernet interfaces exclusively to one domU by using the late binding method and b) to use a bridge between the third interface and dom0 (that works fine). The goal is to not to have to use bridges for the exclusively assigned interfaces. Is it possible? (If not, no need to read the rest) The problem I have is that I
