Oracle VM 从2007年的诞生到现在，已有近10个年头，在内容、功能方面更新了不少，最新版为3.4.2。架构从最开始的OC4J变成了Weblogic ADF (Application Development Framework) web application，数据库也从最开始的Oracle XE变成了现在的MySQL Enterprise，从3.2开始Oracle引入了MySQL数据库，引入了命令行工具，后续又支持了光纤通道，支持从Unified Extensible Firmware Interface (UEFI)引导，引入了OSWatcher等。本文列出了Oracle VM Server和Oracle VM Manager基本管理。
如何安装Oracle VM 3.4(VM Server，VM Manager)
Server Pool：一个服务器池包含一个或多个物理服务器，这些使用服务器共享一个存储库
S e r v e r s：服务器池中的Oracle VM Server，就可以被赋予1到3个服务器功能(Server Pool Master,Utility Server,Virtual Machine Server)
Server Pool Master：一个服务器池中只能有一个Oracle VM Server被授予Server Pool Master，此服务器可以被看作VM Server和外界的通道，负责池中的资源协调 Utility Server：主要负责IO密集型操作(创建、删除、迁移等)，比如虚拟机的创建 Virtual Machine Server：是指虚拟服务器。还用于收集主机和客户操作系统的性能数据。角色为domU的管理程序
如何管理Oracle VM Agent
[root@ohsvms ~]# /etc/init.d/ovs-agent
Usage: /etc/init.d/ovs-agent {start|stop|restart|reload|status}
