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

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?

 

 

if I remove "vif  = [ "mac=00:15:17:AC:00:40,ip=128.224.165.204" ]"

 

I find I can't find a networking interface

 

root@localhost:/root> ifconfig
root@localhost:/root> ifconfig eth0 up
eth0: ERROR while getting interface flags: No such device
root@localhost:/root> ifconfig eth1 up
eth1: ERROR while getting interface flags: No such device
root@localhost:/root> ifconfig -a
