----------------------------------------------------------------------
Can we not rely on secondary storage for config drive? I'd much rather see it
generated dynamically into a temp space or into primary storage alongside root
disk during VM start. It just seems like a bad idea to rely on mounting and
availability of secondary storage (which by design is supposed to be out of
band from running VMs) to have a healthy VM. People put a lot of work into
their primary storage for VM availability, not as much for secondary storage.
The idea of a config drive is good, but moving to a model where secondary
storage has to be mounted and healthy at all times is a big deal and should be
carefully considered.

> To avoid the use of an extra VM for the virtual router we implement
> configdrive for userdata, metadata & password.
> The configdrive ISO is created on the secondary store and the KVM & VMware
> plugins are adapted to accept the configdrive ISO as second cdrom.
> Is applicable for isolated, VPC and shared networks.
