Easy Upgrades and Optimized Performance of Virtual Machines
Virtualization meets Ubuntu with the release of Ubuntu version 7.04 on April 19. This latest version from Canonical Ltd., the commercial sponsor of Ubuntu, features a new upgrade tool and advanced support and optimization for running virtual machines.
Ubuntu is the award-winning Linux distribution for the desktop, laptop, thin client and server which brings together the best of open source software every 6 months. Ubuntu 7.04 Server Edition adds support for hardware facilities that speed up the use of virtual machines, improved hardware support and easy upgrades, making it an excellent choice as a web, database or file and print server which are the fastest growing area of Linux server use.
“Virtualization is becoming de rigueur in the datacenter and we've made it a priority to incorporate it into this latest release,” said Jane Silber, Director of Operations, Canonical. “Our users want choice and ease-of-use, so whether as a guest or host operating system, Ubuntu 7.04 will support commercial virtualization products such as VMWare, as well as open source projects including Xen and KVM.”
On x86 systems with the Intel VT or AMD-V extensions, Kernel-based Virtual Machine support (KVM) allows users to run multiple virtual machines running unmodified Linux. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, and so on. Ubuntu is the first Linux distribution with Para-Ops and VMI support which provides optimized performance under VMware.
Also new is a management tool for the server that enables upgrades to new releases of Ubuntu in a simple, automated manner. This completes the ability to easily and safely upgrade Ubuntu whether you're using it on the desktop or server. The server tool gives Administrators control over how their upgrade will be undertaken and lets them override decisions where required. By default the upgrade tools provides full dependency checking and task upgrades ensuring that the server remains functional. Whether using Ubuntu server on a single system or across a data-centre the ability to upgrade seamlessly will help administrators save time and money.
New features for thin clients include advanced print and sound support through Jetpipe, a printing architecture, and PulseAudio sound server.
In addition to virtualization support and easy upgrades, new features include:
A range of new performance improvements including better performance on multicore processors, support for the Processor Data Area and optimizations for 64-bit architectures.
Improved availability of network services: Improved scheduling for highly parallel services. Services such as SQL and Apache will remain more responsive and stable under heavy loads.
Secure remote network installation: Administrators who aren't physically where their server is can securely install Ubuntu using a remote SSH terminal.
Ubuntu now recognises other operating system installations so that it's easy to install without damaging existing data.
The latest software for developers including new versions of Apache (2.2.3), MySQL (5.0.38), Python (2.5) and PHP (5.2.1).
Updates to the latest software along with the latest GFS and OCFS2. GFS2 and the new local mount capability for OCFS2 are technology previews for Administrators to start testing before production deployments.
