Cloud-init fails to initialize with RHEL8.1 and CentOS8.1 (RPM cloud-
init-18.5-7.el8_1.1.noarch) when routing to the VMs are provider by
virtual router (vrouter). In this scenario, we are spawning a VM on
OpenStack using Contrail as the network provider. With cloud-init-18.5
version, we see the following exception during the VM boot phase causing
- init and finals stages of cloud-init to fail.
