vibootstrap 0.0.2

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
