Microsoft is set to launch its Hyper-V virtualisation technology tomorrow, two months ahead of the company's own deadline.

Though Microsoft would not confirm the release direct, representatives from the company's public relations firm have been spinning about a forthcoming major release tomorrow and hinting that it's Hyper-V. Another source close to the company also said the technology was in its final stages, but asked not to be named.

Microsoft had originally intended to release Hyper-V as part of the original release Windows Server 2008, but the technology was delayed and rescheduled for availability 180 days, or about six months, after shipping Windows Server 2008.

Microsoft delayed the release of Hyper-V, originally code-named "Viridian," because the company opted to pull out some originally planned features.

Virtualisation is becoming a key way companies are driving costs out of the data center by running OSes in virtual containers rather than physically on servers. Microsoft aims to catch up to virtualisation leader VMware in providing this technology for hardware systems not only running on Windows, but also Linux and other OSes.

The company has said it aims to make virtualisation a key part of its system-management strategy going forward, and is also expanding beyond hardware into desktop and application virtualisation.
