@Steven,

For such things to "just work", the platform needs to identify itself.
Without a platform identifying itself, cloud-init (or any other
software) cannot take platform-specific behavior.

The workaround is to configure the datasource_list to contain only OpenStack.  So
  datasource_list: [OpenStack]
or
  datasource_list: [OpenStack, None]


Also, I marked as a bug against Nova. Other bugs like it: https://bugs.launchpad.net/nova/+bugs?field.tag=dsid

Title:
  OpenStack datasource detection fails during init on Hyper-V compute
  nodes

Status in cloud-init:
  Incomplete
Status in OpenStack Compute (nova):
  Confirmed

Bug description:
  The OpenStack datasource detection fails on an Hyper-V compute (Nova)
  node (running on-premises, no cloud provider). It does not try to
  attempt to use the metdata endpoint and the instance fails to
  initialize properly unless another datasource is used (like
  ConfigDrive or EC2, the latter which gives a warning).

  The issue is in cloudinit/sources/DataSourceOpenStack.py, in the
  detect_openstack function. The DMI data does not match anything
  expected.

  In Hyper-V the following info is returned from DMI:
