Gerben’s Blog on Virtualization

Virtualization is becoming a standard

Windows Server Viirtualization Features postponed

Posted by Gerben on 11/5/2007

Just before the launch of WINHEC Mike Neil (GM, virtualization strategy) posted an article on the Windows Server Division Weblog.
Key issues covered:

  • The beta of Microsoft Windows Virtualization (aka Viridian) will be available with the RTM of Longhorn (H2 2007)
  • And the corresponding version of System Center Virtual Machine Manager will be available 60-90 days afterward.

Mike continues to explain what features will be part of the ‘viridian’-release and ends with the following striking paragraph:

"But with all this progress comes the occasional tradeoff. Earlier this week we had to come to grips with some universal truths about product development:
·         Shipping is a feature, too.
·         The quality bar, the time you have, and the feature set are directly correlated.
·         The mythical man-month – resources are not infinite and even if you could add more it does not help get more done faster.
So we had some really tough decisions to make
[…]
So we are making the following changes, and postponing these features to a future release of Windows Server virtualization:
·         No Live migration
·         No hot-add resources (storage, networking, memory, processor)
·         Support limit of 16 cores/logical processors (e.g., 2 processor, quad-core systems is 8 cores; or 4 processor, quad-core system is 16 cores)"
Striking enough these are some of the key features Microsoft showcases with when presenting and demo-ing Windows Server Virtualization.
