Hi, Mark.

The main problem is the cloud-init has not been created to change ip 
configuration after the vm create.  It's really created for vm first 
init, it's "by design" like this.  (yes, that's sucks)


The only way to change ip address, is to regenerated a new cdrom id, to 
get cloudinit launch is early service.
But this also regenerated ssh host-keys.

I have done tests last year, I never was able to skip this.



I known that very last version of cloudinit have support for nic 
hotplug, to add ip on new hotplug iface, but I don't think it's working 
for already existing interface.



Personally, I'm use opennebula guest tools instead cloudinit,
they are simple bash script, easily extendable, udev hook for hotplug is 
working,...

I have added support last year to generate config drive format, it's not 
available in the gui, but can be added in a template manually
