We are pleased to announce Oracle VM 3.3, Oracle’s latest server virtualization product. It deliver enhanced ease of use for x86 and SPARC architectures, improved management features, and expanded support for both Oracle and non-Oracle workloads, including support for OpenStack—providing customers and partners with additional choices and interoperability. This release continues to enable rapid enterprise application deployment and simplify lifecycle management.
Many customers are using Oracle VM 3 today, Oracle VM help customers virtualize the entire Oracle software stack; in addition, as a general purpose server virtualization solution, Oracle VM runs many non-Oracle workloads as well.
With the latest Oracle VM 3.3 release, the product is getting even better and brings greater customer benefits. New Oracle VM 3.3 highlights:
- Fully supported Web Services API: Oracle VM Manager now exposes a fully supported Oracle VM Web Services API that offers both SOAP and REST interfaces to program any action supported within Oracle VM, enabling more automation and interoperability. See the Oracle VM Web Services API Developer's Guide for more information. In addition, the Oracle VM Manager Web Interface and the Oracle VM Manager Command Line Interface have been rewritten to use the new WS-API to provide further consolidation and consistency.
New statistics and events model: The statistics and events model has been entirely rewritten to offer significant performance gains. A queued job task is in place to monitor the number of generated statistics and to adjust the threshold automatically during periods where the number of statistics exceeds the threshold.
Huge Page support: Support for Huge Pages (or Super Pages) has been added to allow guests, hosted on an x86-based server pool, to take advantage of this functionality to improve performance and reduce the I/O that results from page lookups in virtualized environments.
Improvements to guest VM messaging: A change to the Oracle VM Guest Additions messaging facility to support multiple key-value pairs in a single message reduces the number of jobs generated within Oracle VM Manager, resulting in significant performance gains.
Tighter security control: Reduces the number of required open ports to minimize potential access points and security vulnerabilities. To protect and ensure authorized access to Oracle VM Server, a certificate-based authentication model has been implemented for Oracle VM Agent and Oracle VM Manager.
- Virtual machine configuration file view: It is now
possible to view the virtual machine configuration file for any virtual machine
directly within the Oracle VM Manager Web Interface and Oracle VM Manager Command
Line Interface, to provide more transparency for the configuration that is
actually applied to a virtual machine when it is started by the hypervisor.
- Management database consolidation: Oracle VM Manager comes bundled MySQL Database Enterprise Edition, providing automated database backup and integrated tools for database object consistency checking to improve supportability and management. It removes the need for an external database as the backend management repository.
- Inbound migration Lock: A new feature allows you to protect an Oracle VM Server from attempts to move or migrate other virtual machines to that server. This allows you to run selected virtual machines on a specified Oracle VM Server, and to be certain that no other virtual machines are started on the server, consuming resources that may be mission critical for some applications.
- Improved VLAN support: Simplified VLAN support definition enables users to specify VLAN interfaces as needed and to define which ports are used for which VLAN tags, bringing more flexibility to network design.
- Improved SPARC virtualization management and availability: Additional storage types such as Fibre Channel, iSCSI, ZFS volume, and local disk, in addition to NFS, can now be directly assigned to virtual machines running in a SPARC server pool managed by Oracle VM Manager, offering customers more choices when choosing storage with Oracle VM Server for SPARC. Furthermore, virtual machine high availability and support for configuration of redundant I/O service domains improve system availability for business-critical operations.
- Oracle VM Server installation partitioning: The Oracle VM Server Installer now handles all disk partitioning itself, to optimize installation. Part of this process make sure that only the maximum required disk space for the Oracle VM Server software is used. Any remaining disk space is automatically partitioned to be used as a discoverable local disk that can be used to host a storage repository, or attached to a virtual machine hosted on the server. This improvement to disk space usage ensures the best possible use of machine resources. This change is only supported for locally hosted boot disks and does not apply to SAN disks.
- New guides and improved interface coverage: The documentation
has been restructured to provide more comprehensive coverage.
- Infrastructure changes in Oracle VM Manager: Much of the technology used to enable Oracle VM Manager has been updated to take advantage of new features, improved performance and security fixes. Major changes to these components include: Oracle WebLogic Server and ADF upgraded to 12c; Java upgraded to version 7; MySQL Database Enterprise Edition upgraded to version 5.6.
- Infrastructure changes in Oracle VM Server: Major changes
to the underlying technology used for Oracle VM Server on x86 hardware have
been implemented, including: Xen hypervisor upgraded to version 4.3;
Dom0 user space upgraded to Oracle Linux 6; and Dom0 kernel upgraded to Oracle
Unbreakable Enterprise Kernel Release 3 (UEK3). The optimization of the hypervisor and special-built Oracle
Linux with Unbreakable Enterprise Kernel has enabled Oracle VM Server the most
scalable x86 server virtualization solution. Oracle VM 3.3
supports up to 240 physical CPU threads and 6 TB memory, and the guest VM supports up
to 128 virtual CPUs and 2,000,000 MB memory. Such scalability limits have been
tested on Oracle’s
Sun Server X4-8 System.
