We have just announced the availability of OpenNebula 1.2, the second stable release of the project. This is an important milestone for the project and marks that most of the components of OpenNebula are now in place. See this post with the details of the first release.

What is OpenNebula?
The OpenNebula virtual infrastructure engine provides efficient, dynamic and scalable management of groups of interconnected VMs within datacenters involving a large amount of virtual and physical servers. OpenNebula supports Xen and KVM platforms and can interface with remote cloud sites, being the only tool able to access on-demand to Amazon EC2 to dynamically scale the local infrastructure based on actual usage. OpenNebula also exhibits an open and flexible architecture which allows the definition of new algorithms for virtual machine placement, and its integration with any virtualization platform, infrastructure cloud offering and third-party component in the cloud ecosystem, such as cloud-like remote interfaces, virtual image managers, and service managers. OpenNebula is one of the components being enhanced in the context of the European Union’s Reservoir Project, which aims to develop the open source technology to enable deployment and management of complex IT services across different administrative domains.

New Features and Highlights in OpenNebula 1.2
OpenNebula 1.2 presents important improvements in the following areas:

• Image Management. OpenNebula 1.2 features a general mechanism to transfer and clone VM images.

• Networking.The new Virtual Network Manager module allows you to define virtual networks and it leases IP-MAC pairs to VMs, so you do not have to keep track of the addresses in use. Additionally, the leases are built in such a way that you can easily obtain the IP form the MAC when booting the VM.

• Robustness and scalability, OpenNebula 1.2 has been tested in the management of hundreds of running VMs to ensure that the code meets production level requirements.

Getting OpenNebula 1.2

The complete source tree for OpenNebula can be freely downloaded. Additionally the ubuntu virtualization team have kindly provided binary packages for Ubuntu 9.04 (Jaunty Jackalope).
