Hi Alex, I am trying to pass through a PCI device to the guest to compare the MSI interrupt latency with normal device pass through and pass through using VFIO framework. I used the following script for dev in $(ls /sys/bus/pci/devices/0000:06:00.0/iommu_group/devices); do vendor=$(cat /sys/bus/pci/devices/$dev/vendor) device=$(cat /sys/bus/pci/devices/$dev/device) if [ -e /sys/bus/pci/devices/$dev/driver ]; then echo $dev > /sys/bus/pci/devices/$dev/driver/unbind fi echo $vendor $device > /sys/bus/pci/drivers/vfio-pci/new_id done and added "-device vfio-pci,host,host=0000:06:00.0" to my qemu command line. I am getting Error - qemu-system-x86_64: -device vfio-pci,host,host=0000:06:00.0: Property 'vfio-pci.host' doesn't take value 'on'-- when i use the qemu for your git repo and and also the latest v1.3.0-rc1 qemu. I am using Kernel 3.6.7-rt18. Am i missing step ?
