Estonia’s latest Virtualization product is called OpenNode

OpenNode is a CentOS based opensource server virtualization solution , providing the users an easy method to do bare-metal installations supporting both OpenVZ container based virtualization and KVM full virtualization technologies on the same physical host.

The first public preview of their OpenNode technology is available from sourceforge , and a central management framework for multiple OpenNode servers is under development. In the planning are an AJAX based web management framework and a CLI management interface based on func. (Fedora Unifeid Network Controller)

OpenNode is a respin of CentOS, providing a customized CentOS installer which has a couple of special features.OpenNode provides the end user with an easyh to use automated LVM setup, it installs a minimal number of packages that are needed for out of the boxox openvz and KVM support. OpenNode is based on a stable RHEL5 2.6.18 series kernel provided by the OpenVZ project on which they added also support for KVM .
It has automated bridge networking setup for both KVM and OpenVZ veth interfaces.

Their plan is to bridge the gap that Fedora / Redhat leaves because they aren’t supporting openvz while following CentOS as close as possible upstream apart from applying the OpenVZ patches.

OpenNode has been developed by Active Systems from Estonia, who will provide paid support and development for OpenNode.
