Hi, I'm trying to pass a NOVA-T-500 TV Tuner card through to a gust VM. I'm getting the error "The driver 'pci-stub' is occupying your device 0000:08:06.2" I'm running Ubuntu Server 10.10 64bit. I've recompiled the kernel with the default options + DMAR, uname -r = 2.6.35.10-vi I've installed a recent version of QEMU-KVM using the Ubuntu Server Edgers ppa here: https://launchpad.net/~ubuntu-server-edgers/+archive/server-edgers-qemu-kvm qemu -version = QEMU emulator version 0.13.50 (qemu-kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard The hardware is an 890FX based Gigabyte GA-890FXA-UD5 with the IOMMU and VT enabled in the BIOS I've followed this page as a guide on how to get pci passthrough working: http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM Can somebody help me get this working please?
