[one-users] Contextualization

Fri Apr 18 04:50:52 PDT 2014

So what I have to do if I understand correctly:
Create a template in OpenNebula (pastbin template
layout)<http://pastebin.com/cTBZ2wvL>

TEMPLATE 13 INFORMATION
> ID             : 13
> NAME           : empty install template
> USER           : oneadmin
> GROUP          : oneadmin
> REGISTER TIME  : 04/16 14:49:35
> PERMISSIONS
> OWNER          : um-
> GROUP          : ---
> OTHER          : ---
> TEMPLATE CONTENTS
> CONTEXT=[
>   NETWORK="YES",
>   SSH_PUBLIC_KEY="$USER[SSH_PUBLIC_KEY]" ]
> CPU="1"
> DISK=[
>   IMAGE="CD Centos 6.5 Minimal",
>   IMAGE_UNAME="oneadmin" ]
> DISK=[
>   IMAGE="empty disc",
>   IMAGE_UNAME="oneadmin" ]
> GRAPHICS=[
>   KEYMAP="fr-be",
>   LISTEN="0.0.0.0",
>   TYPE="VNC" ]
> MEMORY="1024"
> NIC=[
>   IP="146.175.139.60" ]
> OS=[
>   ARCH="x86_64",
>   BOOT="cdrom" ]

Start the VM with this template.
Install the OS
Open VNC

vi /etc/sysconfig/network-scripts/ifcfg-eth0DEVICE=eth0

> TYPE=Ethernet
> ONBOOT=yes
> NM_CONTROLLED=no
> BOOTPROTO=static
> IPADDR=146.175.139.60

NETMASK=255.255.255.0

Then install the contextualization.

shutdown the VM

Make the Image un-persistent

Ready?
