Oracle VM is an enterprise-class server virtualization solution comprised of Oracle VM Server for x86 and Oracle VM Manager. Oracle VM 3 reflects Oracle’s strategic commitment to deliver Application Driven Virtualization — Virtualization that makes the entire enterprise software and hardware stack easier to deploy, manage, and support so IT and business can be more agile.

Where to Start

Running on x86 servers, Oracle VM includes Oracle VM Manager and Oracle VM Server for x86.

Oracle VM Manager controls the virtualization environment, creating and monitoring Oracle VM servers and the virtual machines. 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) 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 run on one physical machine. The Dom0 runs a process called Oracle VM Agent. The Oracle VM Agent receives and processes management requests, 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.


Multiple Oracle VM Servers are grouped into server pools as shown in the picture. Each server pool can have up to 32 physical servers, and every server in a given pool has access to shared storage, which can be NFS, Fibre Channel or iSCSI (or a combination of these). This allows VMs associated with the pool to start and run on any physical server within the pool. 

When a VM first starts in the server pool, the VM is placed on the server that is the “best” fit based on an algorithm that takes into account the server CPU, memory and network utilization.  Typically the server that is assigned to host the VM has the most resources available. Then the VM is associated with the server, but it can be securely migrated to any other server in the server pool by the administrator or can be load balanced across the pool based on a dynamic resource scheduling policy.

As a result of this architecture, VMs can easily start-up, power-off, migrate, and/or restart without being blocked by the failure of any individual server or by the failure of multiple servers as long as there are adequate resources in the pool to support the requirements for all VMs to run concurrently.
