Virtualization is one of today’s hottest IT technologies, and Windows Server 2008’s new native virtualization feature, Hyper-V, is a significant new competitor that has the potential to change the market. VMware ESX Server is the current market favorite. To make an informed decision about Hyper-V, you need to understand how the architectures of the two products compare. In addition, Hyper-V introduces some important new features, and you’ll want to see how Hyper-V and the older Virtual Server 2005 R2 relate to each other. Finally, to enrich your understanding of Hyper-V I’ll show you how to set it up and use it.

If you look at how paravirtulization works you will see that it is not the virtulization engine running on windows but windows runs as vm1 (also called domain 0 in Xen Virtulization) on Hyper-V. Hyper-V is a true hypervisor

Readers, thanks for your comments. Michael Otey responds: "It’s understandable that readers would like ESX Server. It is an excellent product. hesssco: While Hyper-V is currently delivered with Windows Server 2008, it does not run on top of Windows Server. A standalone version of Hyper-V (no Windows OS at all) is expected to be released later this year. JustinC71: If you review the feature list in the "Feature for Feature" sidebar (link is at the top of the article), you will see the Hyper-V feature set is much more like ESX Server than Virtual Server 2005."

Once again, an application platform running on a secondary OS platform that has proven its inability to manage memory, offer security, require patches too frequently, and run its "family" of applications does not mean much to the average client. Too little too late. Maybe MS can strongarm their vendors into forcing it down the throats of their clients. But, they never do that.

The features you describe for Hyper-V come nowhere near to 'leveling the playing field' with VMWare. The feature set sounds very similar to Virtual Server 2005, only built into the OS and with the ability to run on a Windows Server Core installation.

"These advances level the playing field with VMware’s market leader, ESX Server" - I don't think so. Perhaps you should have a chat with your colleuge Paul Thurrott see Instant Doc #97838
