UbuntuRelease: JeOS 7.10 (Gutsy Gibbon)

Introduction

This page is a work in progress which aims at documenting how to create virtual appliance using JeOS.

Initial setup

At this point in time, JeOS is meant to run under VMWare Server or WMWare ESX and may not work under other virtualization technologies yet. It is assumed in this tutorial that you have already installed a VMWare environment.

Download JeOS

The latest version of JeOS iso image can be downloaded from [http://cdimage.ubuntu.com/jeos/releases/].

wget http://cdimage.ubuntu.com/jeos/releases/7.10/release/ubuntu-7.10-jeos-i386.iso

It is always a good idea to verify the md5 sum of the downloaded file by comparing the content of [http://cdimage.ubuntu.com/jeos/releases/7.10/release/MD5SUMS] with the result of

md5sum ubuntu-7.10-jeos-i386.iso

If the values are not the same, you should try to reload the file again.

Initial installation of JeOS

Installation of JeOS is done the same way you would install any other OS in VMWare, but here are a few thing to consider:

• Please note that in order to reduce the size of JeOS to a minimum SCSI drivers have not been included in the JeOS kernel. Please make sure that you instruct VMWare to use IDE drive instead.

• If you plan on shipping a virtual appliance, do not assume that the end-user will know how to extend disk size to fit their need, so either plan for a large virtual disk to allow for your appliance to grow, or explain fairly well in your documentation how to allocate more space.
• Given that RAM is much easier to allocate in a VM, RAM size should be set to whatever you think is a safe minimum for your appliance.

Defining the VMWare machine

The following example is based on using VMWare server:
