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.
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.
