The support for multiple instances of the operating system in SuSE Linux Professional 9.3 comes through software called, an open-source package that competes with products from Microsoft and EMC's VMware and has won big-name endorsements. Novell is adding the technology, which is useful for a number of tasks, to give programmers new abilities, said Greg Mancusi-Ungaro, director of marketing for SuSE Linux.
Xen provides a foundation called a virtual machine that an operating system thinks is a real computer. Running an operating system on such a foundation provides developers a painless way to test new software without risking damage to a primary computer. For example, they don't have to worry that a crash will corrupt essential system files.
However, Xen is still in fairly raw form. The software will be included with the Linux version but isn't installed by default, Mancusi-Ungaro said.
Novell announced the new Linux version at the CeBit trade show in Germany on Thursday. The cost in Europe--where SuSE Linux sales are strongest--will be 74 euros ($99), but U.S. pricing won't be set until closer to the product launch date, Mancusi-Ungaro said.
SuSE Linux Professional is geared for desktop computer tasks such as word processing, programming or playing digital videos. Novell hopes Windows users wanting to breathe new life into older computers will be interested.
Novell will offer a "Live DVD" version that can be run directly off a DVD drive to let people experiment with but not install the software. And about eight weeks after release, an installable version will be available for free download, Mancusi-Ungaro said.
SuSE Linux Professional 9.3 also adds the Linphone software for voice over Internet Protocol (VoIP); the Web browser; and the F-Spot photo organizer software. And it comes with the latest versions of graphical interface software, 2.10 and KDE 3.4.
The Professional product line changes more quickly and includes newer features than the company's premium product,, and its corresponding desktop version, .
Xen is "" software that runs directly on a computer's hardware, managing operating system access to memory, input-output subsystem and other resources. So far, Xen only can run modified versions of Linux on x86 processors such as Intel's Pentium, but work is under way to extend it to other operating systems and processor domains.
, the No. 1 Linux seller, also has begun adding geared for Linux enthusiasts and programmers. The virtualization tasks Xen and its rivals must accomplish are expected to become easier with the arrival of new from Intel in 2005 and Advanced Micro Devices in 2006.
