Oracle VM is free, next generation, scalable server virtualization software that supports Oracle and non-Oracle applications. Oracle VM provides an easy-to-use graphical interface for creating and managing virtual server pools running on x86 and x86-64-based systems across an enterprise; both Linux and Windows guests are supported. Part of Oracle VM includes the Xen hypervisor, and Oracle's engineering team contributes heavily to feature development of Xen mainline software—Learn More.

| Certifications |
Oracle performs real-world testing on its broad portfolio of products with Oracle VM to ensure bulletproof reliability and streamlined support. Refer to note 464754.1 on Oracle's MetaLink support website for the latest information on exact product versions certified. Oracle VM is the only x86-based server virtualization environment on which Oracle products are supported; refer to MetaLink note 249212.1 for more details. |
| Patch Management |
Support customers can obtain updates for Oracle VM through the Unbreakable Linux Network (ULN). |
| CONTROL/MANAGEMENT FEATURES |
| Centralized Control of Servers and VMs Pools |
Oracle VM Manager provides a single point of control for the allocation of virtual machines to physical servers. Administrators can perform maintenance and provisioning tasks, set policies, and collect data from a remote or local node via a web interface. An integrated Oracle Database keeps track of all the information about your configuration. |
| HA Clustered OVM Manager |
Using Oracle Clusterware in your setup, if the server running OVM Manager and the underlying database had to fail, they would be automatically restarted on a different server.
|
| Oracle VM Management Pack |
Oracle Enterprise Manager 10g Release 5 introduces the Oracle VM Management Pack, which provides a comprehensive management solution for managing both the virtual machines and the operating systems and software running inside the virtual machines from a single product. The Oracle VM Management Pack provides integrated in-depth health and performance monitoring, configuration management, and lifecycle automation for both virtual- and physical infrastructure for maximum operational efficiency. |
| GENERAL FEATURES |
| Secure Live Migration |
New in Oracle VM 2.1.2. Dynamically reallocate running virtual machines using SSL encrypted secure live migration. OVM is the first commercially available virtualization product to offer secure migration out of the box. No need to purchase special hardware or deploy special secure networks. |
| High Availability |
Oracle VM uses robust clustering techniques to assure minimal downtime. OVM uses network and storage heartbeats to determine node status and automatically restart or migrate VMs on physical server or network failures. Server pool load balancing algorithms assure the best allocation of resources to each VM.
Oracle VM supports High Availability on all supported storage methods, including iSCSI, SAN, NAS, etc.
|
| Distributed Lock Management |
An essential part of VMs failures detection and recovery, Distributed Lock Management guarantees that no duplicates VMs are created due to erroneous VM status reporting. |
| Pool Load Balancing |
Optimize allocation for VM to servers based on memory requirements and node availability. Oracle VM performs automated load balancing at each virtual machine power on. |
| Shared Storage |
The server pools can be configured using shared storage on NFS, OCFS2 on SAN, or OCFS2 on iSCSI. |
| Utility Servers |
It is possible to configure the server pool to have a dedicated server for VMs backup and restore. |
| Oracle VM Manager Web Services API |
Enable integration of third party products with Oracle VM Manager. |
| ADMINISTRATION/DEVELOPMENT |
| VMs Conversion |
Convert Linux or Windows physical images to Oracle VM virtual machines using the P2V utility. Migrate safely from other virtual machines formats to OVM using the V2V utility. The physical images need to be of one of the OVM supported guests operating systems, the target server needs to be hardware virtualization capable.
|
| Easy Clones Creation |
Create, duplicate or archive VMs in a simple direct way.
|
| Oracle VM Template Creation with Oracle Enterprise Linux JeOS |
With Oracle Enterprise Linux JeOS (Just Enough OS)—a secure, minimized OS that is freely re-distributable and backed by enterprise-class support—developers and ISVs can now easily build Oracle VM Templates. JeOS includes a pre-packaged, small-footprint Oracle Enterprise Linux image (either OEL 4.7 or OEL 5.2) for x86 and x86-64, along with a script to customize the image. Learn More |
| Oracle VM Templates |
Oracle VM Templates provide an innovative approach to deploying a fully configured software stack by offering pre-installed and pre-configured software images, including Oracle database, middleware, and applications, and more. Use of Oracle VM Templates eliminates the installation and configuration costs, and reduces the ongoing maintenance costs helping organizations achieve faster time to market and lower cost of operations.
