VM is not getting IP assigned in secondary interface even though we are able to see the IP attached in openstack server show output.

Issue

• VM is not getting IP assigned in secondary interface even though we are able to see the IP attached in openstack server show output.

• When we are checking inside the VM ports are showing down when we are bringing the port up manually it is coming up but ip is not getting assigned.

• Even after rebooting the VM IP is not getting assigned on secondary interface and we have to manually attach the ip.

• If we reset cloud-init, second interface is getting an IP:

  rm -rf /var/lib/cloud/*
  cloud-init clean
  cloud-init init 
  reboot
  

• We generated our own KVM guest images.
