Contextualization packages are available to several distributions so you can prepare them to work with OpenNebula without much effort. These are the changes they do to you VM:

• Disables udev net and cd persistent rules
• Deletes udev net and cd persistent rules
• Unconfigures the network
• Adds OpenNebula contextualization scripts to startup

These packages are destructive. The configuration for networking will be deleted. Make sure to use this script on copies of your images.

There are two packages available:

• Debian: Compatible with Ubuntu 11.10/12.04 and Debian Squeeze
• CentOS: Compatible with CentOS and RHEL 6.x

After the installation of these packages the images on start will configure the network using the mac address generated by OpenNebula. They will also try to mount the cdrom context image from /dev/cdrom and if init.sh is found it will be executed.
