Microsoft releases Viridian hypervisor along with Windows Server 2008 RC0

Quoting from: http://www.virtualization.info/2007/09/microsoft-releases-viridian-hypervisor.html

Few hours ago WinBeta broke the news Microsoft just released Windows Server 2008 RC0 to TAP customers.

Now virtualization.info has learned from trusted sources that this new version contains first preview version of new Microsoft hypervisor Windows Server Virtualization (WSV), codename Viridian.

As expected the hypervisor comes as a server role, but the surprising news is that virtualization role is available also for complete installations of Windows, not only Server Core one as originally stated by Microsoft.

This may change once started the beta program, but if it stays this way it may imply Microsoft is changing its plans for hypervisor integration, and may even consider embedding a specific version for desktop operating systems (e.g.: Vista).

Once activated the new role will reboot the machine in hypervisor mode, putting Windows operating system in the so called Parent Partition, as Viridian architecture implies.

If TAP customers have access to this preview it means general public will access beta 1 within the end of this year or early 2008.
