A simple kickstart based virtual image bootstrapping tool
Project description
Virtual Image Bootstrapping Tool.
Designed to build an image from nothing (IE via netboot/kickstart), strip it down and re-package it for different targets.
Created due to the huge amount of manual work involved in re-packaging images for new versions of things.
Expected setup
Requirements:
- Hardware virtualization support
- 64bit host (if you want to build 64bit images)
- Standard qemu setup (default NAT’d network)
Packages installed:
- python-libvirt
- qemu
- qemu-system
- qemu-kvm
- libvirt-bin
- bridge-utils
- libguestfs-tools
Validate the install:
damian@Capricorn:~$ virsh -c qemu:///system net-list Name State Autostart —————————————– default active yes
Workflow
- virt-install the machine
- serve up a ks file based off the template
- run the scripts
- shutdown the machine
- virt-prep the machine
- undefine it
- save the image
- run qemu-img convert against the image for all desired formats
Example:
>> cat ubuntu-base.conf distro: ubuntu release: saucy target: server arch: x86_64 source: http://mirror.bytemark.co.uk/%(distro)/dists/%(release)/main/installer-%(arch)/
packages: - ubuntu-minimal - openssh-server - salt-minion - puppet
post-scripts: - ../scripts/bootup-generic.sh
images: - vmdk - vdi - qcow2 - raw
>> cat ubuntu-13.10-i386.conf include(‘ubuntu-base.conf’) release: saucy target: server arch: i386
>> ls ./ubuntu/ - bootup-generic.sh - ubuntu-base.conf - ubuntu-13.10-i386.conf - ubuntu-12.10-i386.conf
