Public bug reported:
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.

ValueError: Unknown network_data link type: vrouter
The error seems to be coming from
/usr/lib/python3.6/site-packages/cloudinit/sources/helpers/openstack.py file
which only expects 'link' type to be only of one of the following:
valid_keys = {
'physical': [
'name',
'type',
'mac_address',
'subnets',
'params',
'mtu',
],
However, with Contrail, the network_config object that gets passed to
the method convert_net_json looks something like the following object:
{
"services": [],
"networks": [
{
"network_id": "f42c8806-c128-4ef8-af9e-d4a3856dde23",

"id": "tap722bcc7f-5a",
"mtu": null
}
]
}
Impact: cloud-init fails to inject ssh-keys, grow root partition and other
critical functions.
Version cloud-init-18.2-6.el8.noarch of cloud-init did not have this
issue.
