IDG(美国国际数据集)新闻服务—红帽已经发布了红帽企业虚拟化RHEV的第三个版本虚拟化技术软件包，它有了很大的提升，其中包括于较大规模的部署和一个新的自控制台自备置。
为企业内部的基于内核的虚拟机（KVM）准备，并考虑在公司内更广泛使用的产品，比如虚拟系统（VMware）和微软等公司的产品， 知名的IDC云和虚拟化分析师Gary Chen，RHEV3.0是向前迈出了重要的一步。.
红帽推出的RHEV最近才进入虚拟化市场，在2009年后，VMware、Citrix和微软等公司已经建立了在该领域内的市场份额。RHEV的独特之处在于它在控制台中结合的能力，来管理虚拟服务和虚拟桌面。自推出以来这个软件已经有了大量的用户数，比如IBM，NTT通讯公司和动画梦工厂。
红帽在参与的开放式虚拟化联盟中一直鼓励广泛使用KVM，一个产业群就如何更好地使用该技术生成了文件和建议。
RHEV的基础是开源的，基于内核的虚拟机（KVM）管理程序，在他的发展中受到红帽的工程师大力帮助
红帽RHEV3.0相比于过去的2，0版本已经有了1000个新特性，这个版本是第一个拿出一个门户网站，允许用户使用他们自己的虚拟机，这相应减轻了管理员的管理负担。这个桌面组件现在允许在本地客户机上存储数据。这个软件还有一个RESTful API（以状态传输为基础的应用程序编程接口），它允许RHEV的某些功能是从其他程序中访问。
另外还有一些改进如软件的可扩展性，这时首次将测试版在八月份底发布。现在，它现在能支持多达64位的虚拟CPU和2TB的内存，与以前的主机相比同比增长超过16个虚拟CPU和256GB的内存。

Red Hat RHEV pressed into action
Red Hat RHEV 3.0 makes a serious play for the enterprise virtualization market

IDG News Service - Red Hat has released the third version of its Red Hat Enterprise Virtualization RHEV virtualization software package, which includes improvements that would make it suitable for larger deployments, and a new console for self-provisioning.
RHEV 3.0 represents a significant step forward for the readiness of KVM within the enterprise, and should be considered as a viable virtualization alternative to more widely used products from companies such as VMware and Microsoft, noted IDC cloud and virtualization analyst Gary Chen.
Red Hat introduced RHEV only recently into the virtualization market, in 2009 after VMware, Citrix and Microsoft had already established market share in the field. RHEV is unique in that it combines in one console the ability to manage both virtual servers and virtual desktops. The software has gained a number of high-profile users since its launch, such as IBM, NTT Communications and DreamWorks Animation.
Red Hat has been encouraging the wider use of KVM through its participation in the Open Virtualization Alliance, an industry group that generates documentation and recommendations on how to best use the technology.
At the base of RHEV is the open source Kernel-based Virtual Machine (KVM) hypervisor, the development of which has been heavily aided by Red Hat engineers.
RHEV 3.0 has 1,000 new features since the 2.0 release, according to Red Hat. This version is the first to come with a portal that will allow users to provision their own virtual machines, potentially easing the management burden for administrators. The desktop component now allows for data to be stored locally on client machines. The software also has a RESTful API (Representational State Transfer-based Application Programming Interface), which allows certain features of RHEV to be accessible from other programs.
Additional improvements have also been made to improve the scalability of the software, which was first released in a preview edition last August. It can now support as many as 64 virtual CPUs and 2 terabytes of memory for hosts, an increase over the previous limit of 16 virtual CPUs and 256 gigabytes of memory per machine.
