Complete OpenNode OS Usage Guide is currently under active development - howto's section and some usage examples below.

If in need to migrate OpenNode OS from single disk installation (no hardware raid) to linux software raid setup (RAID1) - please use this recipe. Conversion can be done online without much interrupting server operations besides a bit reduced disk IO.

• Download and burn OpenNode OS ISO installer image
• Boot server from OpenNode OS install CD
• Follow installer on-screen instructions
• Choose automatic partitioning (if server has hardware RAID or RAID is not needed). Automated partitioning creates all needed partitions and LVM volumes on servers first harddisk or RAID disk - if server has several harddisks or RAID disks and there is a need to spread initial partitions over these then manual partitioning is needed (or migrating LVM volumes later manually).
• Choose automatic partitioning with softraid setup (if server has no hardware raid and softraid setup is desired)
• Follow installer on-screen instructions to complete the installation and reboot

This howto is about using standard virt-manager GUI tool for KVM VM management. In its current state virt-manager is not capable of fully managing OpenVZ linux containers - so it's mainly a alternative GUI tool for doing KVM VM management with OpenNode OS - and not supporting all features that OpenNode OS may have. However we try to make virt-manager user experience as smooth as we can by pre-configuring libvirt for OpenNode related policies as much as possible.

As a GUI alternative its possible to use virt-manager application for KVM VM installs. Please see this howto for more details: KVM VM management with virt-manager GUI tool

In order to simplify iptables firewall configuration we have included a Shorewall firewall package (http://www.shorewall.net) - a gateway/firewall configuration tool for GNU/Linux.

Please see Quickstart Guide

There can be situations when using OpenNode ISO installer or doing networked PXE installs is not possible (for example in case of pre-installed dedicated server offerings) - therefor we have created an helper script in order to assist converting existing CentOS installations into OpenNode compatible hosts.
