Linux becomes platform of choice for Vienna
Red Hat Inc. announced last week that the city of Vienna has selected Red Hat Enterprise Linux (RHEL) as its server platform of choice. The city is using Linux for mission-critical applications like database servers and for other systems including file servers.
To date, the city of Vienna has migrated more than 100 servers to RHEL. The city runs Red Hat Enterprise Linux ES for its Samba and Apache servers, as well as legacy applications written by the city of Vienna itself. Oracle databases run on Red Hat Enterprise Linux AS. In the future, the city of Vienna expects to migrate its AIX-Unix databases to Red Hat Enterprise Linux AS running PostgreSQL.
OpenVZ update delivers live migration
The OpenVZ project has released fully tested and performance-tuned live migration and Virtual Ethernet device features for its operating system-level server virtualization software. The release comes in a stable branch as a Linux 2.6.9 kernel. Previously, those features were only available in the development branch of OpenVZ software.
Delivery of the "checkpointing" and live migration functionality allows systems administrators to move virtual servers between physical servers without disrupting end users or adding costly storage capacity.
With checkpointing and live migration, the state of a running virtual environment is frozen and the image is stored on disk then restored on another server. The function executes between any two servers on a network, so the capability works for any server and any application. OpenVZ delivers this capability without additional requirements, such as a storage area network.
Also, the virtual Ethernet device function allows network devices to be created inside virtual environments using designated names and hardware addresses (as in a MAC address) that are different from the actual physical device.
