Hi , My goal is to assign pci device using Vt-d capability. I have a Supermicro Server X8DTU-F motherboard. I verified that it had Vt-d capability and enabled it in BIOS. Iam using KVM-86 (as I had some compilation error in KVM-87). My first try was to use Ubuntu 9.04 (with kvm modules from kvm-86) to assign my ethernet controller to guest Ubuntu 9.04. I didn't notice any error messages when I ran qemu-system-x86_64. I was able to see the pci device in the guest system using lspci, the drivers were loaded but I could get an IP address. I then followed the steps described in "how-to" and try to run the same setup with 2.6.30.1 (only in this kernel I can enable DMA remapping and pci-stub driver). This time I got the following error messages while running qemu-system-x86_64. sudo ./qemu-system-x86_64 -hda /home/ami/vdisk.img -m 1G -net none -pcidevice host=01:00.1 assign_irq: deassign: Invalid argument assign_irq: deassign: Invalid argument assign_irq: deassign: Invalid argument assigned_dev_update_msix: deassign irq: Invalid argument assigned_dev_update_msix: deassign irq: Invalid argument fail to set MSI-X entry number for MSIX! Invalid argument assigned_dev_update_msix_mmio: Invalid argument I couldn't see the pci device in the guest OS (Ubuntu ) I have also tried it on another Server board with similar results, i.e even if lspci shows successfully , cant get ip address I would appreciate any help on this. Am I missing anything ?
