Oracle公司Linux和虚拟化产品副总裁Wim Coekaerts表示：“Oracle VM 2.2的发布让用户可以利用服务器虚拟化技术的最新升级功能来更好地管理虚拟环境，削减数据中心的成本和能耗。除此之外，，这次发布为现有Virtual Iron用户向Oracle VM的第一阶段迁移路径，进一步完善了Oracle的虚拟化路线图。”
Oracle VM 2.2是引入Virtual Iron管理工具和功能集的第一步。按照计划，Oracle将为明年下半年提供Oracle VM 3.0，预计这次发布将集成Virtual Iron服务器虚拟化产品中的所有功能特性。为了不让Virtual Iron的现有用户等待太长时间，Oracle适时地发布了这款Oracle VM 2.2来帮助这些用户。Oracle VM 2.2将帮助这些用户更轻松地将Virtual Iron虚拟机迁移到Oracle VM中。
这次发布的Oracle VM 2.2是基于开源Xen 3.4 hyperivsor的，采用了Oracle Enterprise Linux 5.3作为系的dom0。因此Oracle VM 2.2对于那些运行英特尔至强5500系列处理器或者六核AMD皓龙处理器的用户来说性能提升有所加强。
另外Oracle VM 2.2还提供了范围更大的硬件支持，在32位或者64位x64处理器上提高了针对硬件虚拟化和并行客户操作系统的可扩展性和安全性。Oracle支持Oracle Enterprise Linux 4和5；RHEL3、4和5；Windows Server 2008 SP1、Windows Vista、Windows Server 2003、Windows XP Pro和Windows 2000。
Oracle最新的hypervisor支持1TB主内存和64个逻辑CPU。一个虚拟机，在一个32位服务器上可以扩展为32个内核和63GB虚拟内存，在64位服务器上可扩展支持510GB虚拟内存。它在每个虚拟机池中支持128个虚拟磁盘设备，用针对并行化客户操作系统过的31个虚拟网络接口和针对硬件虚拟化客户操作系统的8个虚拟网络接口。
