Comment 15 for bug 1836682

Hi Sathish,

To check whether the NIC has been passed to the VM successfully. You need to use an image which contains the driver required by the passed NIC. You can try the following image:
   http://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64-disk1.img

To ssh the VM, you need to create a security group which allows ICMP, TCP, UDP to the VM. You also need to create a keypair. You can refer below commands:
   mdkir -p /home/sysadmin/.ssh/
   vi /home/sysadmin/.ssh/id_rsa
   openstack keypair create key1 --private-key /home/sysadmin/.ssh/id_rsa
   openstack security group create security1
   openstack security group rule create --ingress --protocol icmp --remote-ip 0.0.0.0/0 security1
   openstack security group rule create --ingress --protocol tcp --remote-ip 0.0.0.0/0 security1
   openstack security group rule create --ingress --protocol udp --remote-ip 0.0.0.0/0 security1
   openstack server create --image ubuntu --flavor m1.medium.pci_passthrough --network public-net0 --security-group security1 --key-name key1 test-pci
   (public-net0 is a normal network. You will need an IP allocated from public-net0 to ssh the VM)

Then you can ssh the VM through dhcp namespace:
   ip netns
   sudo ip netns exec $UUID bash
   ssh -i /home/sysadmin/.ssh/id_rsa ubuntu@192.168.101.208

To verify the NIC has been passed, you need to verify the driver has been loaded in the VM:
   lsmod | grep $DRIVER

If the driver has been loaded, you can find a NIC which has the same MAC address as the passed NIC:
   ip link

The PCI address will change when you use below command to check. But it should has the same description as in the host.
   lspci
