Oracle VM 2.2, the latest release of Oracle’s server virtualization software, is now available, enabling customers to accelerate deployment of and simplify management of enterprise applications; and to run their data centers in the most environmentally-sustainable and efficient manner.
Oracle VM 2.2 features the latest Xen-based, industry-standard hypervisor, Xen 3.4, and provides substantial performance enhancements for customers running Intel Xeon processor 5500 series based on Intel microarchitecture, codenamed Nehalem, as well as Six-Core AMD Opteron processors. Oracle VM 2.2 features new CPU power management, memory management, and direct disk I/O capabilities.
Additionally, this release delivers on the initial integration of Oracle VM and Virtual Iron technology, including the ability for customers to easily migrate Virtual Iron virtual machines to Oracle VM images.
Oracle VM supports both Oracle and non-Oracle applications and offers customers scalable, low-cost server virtualization backed by Oracle’s world-class support.
By leveraging the latest Xen 3.4 hypervisor and a newer dom0 kernel based on Oracle Enterprise Linux 5.3, Oracle VM 2.2 helps provide broader hardware support, and better performance, scalability and security for both hardware virtualized and paravirtualized guests. Performance can be improved for hardware virtualized guest operating systems including Microsoft Windows. Oracle VM 2.2 provides updated support for the Oracle Cluster File System (OCFS2) 1.4 to leverage advanced features such as sparse file support to enable faster virtual machine provisioning and cloning, and to allow users more control over file data allocation, improving performance and storage efficiency.
Oracle VM 2.2 adds direct support for multipath storage devices that can be assigned to virtual machines and enhance performance of clustered applications. By leveraging the Xen 3.4 hypervisor, Oracle VM 2.2 also provides more efficient CPU power management, enabling greener computing and cost savings.
Resource management has been enhanced in Oracle VM 2.2 by allowing users to set the scheduling priority for virtual CPUs in virtual machines and cap the maximum percentage of CPU time each individual VM can access. With this enhancement, users can now control the Quality of Service (QoS) for CPU, network, and disk I/O through the intuitive Oracle VM Manager browser interface.
Other enhancements to Oracle VM 2.2 include a number of user interface enhancements, improved high availability with automatic failover of server pool master agents, and enhanced serviceability and audit features.
