OVM和OVS概述

?Oracle VM Manager controls the virtualization environment, creating and monitoring Oracle VM servers and the virtual machines. Oracle VM Manager serves as the only administrative interface to the Oracle VM servers, unlike previous-generations of Oracle VM that were jointly administered from the management server, as well as locally from the command-line for each Oracle VM Server. Oracle VM Manager 3 is an Oracle Fusion Middleware application based on the Oracle Weblogic Server application server and Oracle Database. The Oracle VM Manager runs on 64-bit Oracle Linux 5.5 OS or later. For its management repository, Oracle VM Manager uses an Oracle Database, which can be installed either on the same management server or a separate server. Oracle Database 11g Express Edition (XE) is bundled with Oracle VM Manager 3 for customer evaluation purposes, but Oracle Database Standard Edition (SE) or Enterprise Edition (EE) it is required for production support as the management repository. All necessary licenses, including licenses for Weblogic Server and Database (SE or EE), are included at no additional charge.

 

Oracle VM Server for x86 installs directly on server hardware with x86 Intel or AMD processors and does not require a host operating system. An Oracle VM Server is comprised of a hypervisor and privileged domain (Dom0) that allows multiple domains or virtual machines (i.e. Linux, Solaris, Windows, etc.) to be run on one physical machine. The Dom0 runs a process called Oracle VM Agent. The Oracle VM Agent receives and processes management requests, and provides event notifications and configuration data to the Oracle VM Manager. Oracle VM Server 3 requires 64-bit x86 hardware, but can support either 64-bit or 32-bit guest virtual machines.

 

每一个Server Pool最多支持32个物理机；建议生产系统不要用服务器的本地硬盘而改用存储。
