At this point in time, JeOS is meant to run under VMware Server, VMware ESX, and KVM. It may not work under other virtualization technologies yet. It is assumed in this tutorial that you have already installed a VMware or KVM environment. We also assume that you know how to use a text based text editor such as nano or vi. If you have not used any of them before, you can get an overview of the various text editors available by reading the PowerUsersTextEditors page.
For information on setting up a KVM environment using libvirt see the section called “libvirt”.
The latest version of JeOS iso image can be downloaded from the Ubuntu website. To download JeOS using the command line utility wget from a terminal prompt enter:
wget http://cdimage.ubuntu.com/jeos/releases/8.04/release/ubuntu-8.04-jeos-i386.iso
It is always a good idea to verify the md5 sum of the downloaded file by comparing the content of JeOS MD5SUM with the result of:
md5sum ubuntu-8.04-jeos-i386.iso
If the values are not the same, you should try to download the file again.
