Hi folks, I'm using kvm and qemu upstream on https://github.com/avikivity The following command line was right for me about three weeks ago, but now I meet some error. # qemu-system-x86_64 -m 1024 -smp 2 -device pci-assign,host=0e:00.0 -hda /root/rhel6u1.img output error is like following. qemu-system-x86_64: -device pci-assign,host=0d:00.0: Parameter 'driver' expects a driver name Try with argument '?' for a list. But I found the qemu document docs/qdev-device-use.txt said the following. "The new way is -device pci-assign,host=ADDR,iommu=IOMMU,id=ID " Even if I add "iommu=IOMMU,id=ID" to my command line, I will meet the same error. I also found this page said the same command line with mine. http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM Anybody know what's wrong with my command line? or this is a qemu bug ? thanks very much.
