Just wanted to bring Jeff's blog to your attention. In Jeff own words
"I’m Jeff Woolsey, a Senior Program Manager at Microsoft focused on Microsoft Virtualization. I’ve worked on virtualization technology for over ten years such as Virtual PC for Mac, Virtual PC for Windows and Virtual Server. These days I spend most of my time on Virtual Server and our new hypervisor based virtualization (codename “Viridian”) which will be a key technology of Windows Server 2008"
I am sure we can expect some great things.
