OpenNode是一个服务器的虚拟化解决方案，提供了一个易于使用 （CentOS /红帽为基础）裸机安装程序和标准，同时支持OpenVZ的基于容器的虚拟化和在同一个物理主机出现全面的KVM">虚拟化技术。在 OpenNode标准安装程序将设立具有以下特点最小CentOS 5服务器系统：红帽2.6.18内核（由OpenVZ项目）修改，以同时支持OpenVZ和KVM虚拟化，libvirt的管理OpenVZ和切换管理程 序，函数接口支持（通过https：/ / fedorahosted.org /函数/）为中央管理的目的客户端支持，和VM模板，opennode CLI工具提供下载（目前只提供OpenVZ的模板）。
