虚拟化解决方案 OpenNode 6.0 Beta1 发布

     <p>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）。<br /> </p>    <p><img style="width:555px;height:420px;" title="22074432_ynyn.jpg" border="0" alt="22074432_ynyn.jpg" src="https://simg.open-open.com/show/401738c9d9f3ea4a3e3f278248b681b9.jpg" /><br /> <br /> OpenNode 6.0 Beta1 发布了，该版本基于 CentOS 6，更新了 OpenVZ 和 KVM 虚拟堆栈，增加 OpenVZ VSwap 支持。<br /> 项目地址：<a href="/misc/goto?guid=4958193760307943092" target="_blank">http://opennode.activesys.org/</a></p>    <div style="margin-right:150px;">     <div class="csc-textpic-text">      <div>       <p><strong>OpenNode Cloud Platform</strong> is a open source server virtualization and management solution which currently consists of following components:</p>       <ul>        <li><strong><a href="/misc/goto?guid=4958193761075812550" target="_self">OpenNode bare-metal installer</a></strong> - providing easy to use (CentOS / RHEL based) bare-metal ISO installer and supporting both OpenVZ containers and emerging KVM full virtualization technology on the same physical host.
