Yes, you're missing the required parameters for the domU kernel.

See: http://wiki.xensource.com/xenwiki/XenPCIpassthrough

Thanks Pasik "I will add "iommu=soft swiotlb=force"。does it add into "domU.cfg" file with

    disk = ['tap:aio:/domU.image,xvda1,w', 'tap:aio:/domUswap.image,xvda2,w']
    kernel = "/bzImage"
    vcpus=2
    vif = [ "mac=00:15:17:AC:00:40,ip=128.224.165.204" ]
    root = "/dev/xvda1 ro"
    extra= "xen console=hvc0 iommu=soft swiotlb=force"
    pci = ['05:00.0']

I just want to let domU nic using my pci nic directly. do I need to change my " vif = [ "mac=00:15:17:AC:00:40,ip=128.224.165.204" ]" or remove it?

Thanks

Lei
