DataSourceOpenNebula.py doesn't configure network

[Akihiko Ota]

I am using OpenNebula 5.4 cloud environment.
I tried to create Ubuntu 16.04 server instance from image that is installed cloud-init 0.7.9-233-ge586fe35-0ubuntu1~16.04.1.
The configuration of HOSTNAME and SSH_PUBLIC_KEY works fine, but network configration doesn't work and fallback to dhcp.

It seems that DataSourceOpenNebula.py creates the soruce of network configrations from context.sh, but it has no appropriate network_config property. So cloud-init doesn't get network configuration.

I wrote attached patch. It works fine on my environment.

my cloud provider:
   OpenNebula 5.4

instance's cloud-init:
   $ dpkg-query -W -f='${Version}' cloud-init
   0.7.9-233-ge586fe35-0ubuntu1~16.04.1

   This instance's image is downloaded from Ubuntu Cloud Images (https://cloud-images.ubuntu.com/).

And attached another patch which is support for Predictable Network Interface Names.
This patch fixes Bug #1716397 .

Hello Akihiko Ota, or anyone else affected,

As part of a stable release update, this changeset is committed and accepted cloud-init into artful-proposed and xenial-proposed as cloud-init version 17.2-35-gf576b2a2-0ubuntu1. The package is now available in the specific -proposed repository and can be installed and tested on artful and xenial instances with something like the following:

sed -i 's/ xenial / xenial-proposed /' /etc/apt/sources
sudo apt-get update
sudo apt-get install cloud-init;
sudo cloud-init clean --logs --reboot; # For a fresh install run

If there are concerns please comment on LP: #1747059.

Hello Chad Smith,

I have updated cloud-init to 17.2-35-gf576b2a2-0ubuntu1 on xenial
and artful instances running in my OpenNebula environment. It's
working fine. Thank you!

This bug is believed to be fixed in cloud-init in 18.1. If this is still a problem for you, please make a comment and set the state back to New

Thank you.
