As the tried & true saying goes: "You get what you pay for". That being said there are some for whom the up front acquisition cost is the overriding factor and if that's the case then Hyper-V may be the solution they need to go with.

Interesting claim on superior performance. Any data to back that up, or is that just pulled out of your ass? Cause the independent performance tests show that it's a wash between VSphere/Hyper-V/Xen, different hypervisors do different things better.

"Virtualization plays a relatively minor role at Microsoft ... It is hard to imagine the Redmond giant truly fired up about Hyper-V with so much going on from Office 2010 to Xbox to Bing."

Microsoft is involved in so many different areas, couldn't you say the same thing about most of its products? Hyper-V -- and other products that don't get as much of the spotlight -- still have a lot of resources behind them.

Richard,
You bring up a good point about lack of published comparisions showing superior vSphere comparisons (though here is one from a couple of weeks ago showing the disparity in enterprise capabilities) https://searchsystemschannel.techtarget.com/generic/0,295582,sid99_gci1512106,00.html
My comment was specifically related to vSphere enhanced performance for enterprise large workloads with attributes such as VMDirectPath to deliver superior I/O performance to large workloads and the lack of going through a parent partition.

Colin,
I agree that with Microsoft's resources, even minor products get plenty of attention. That being said, I know that when I was an MVP for Terminal Server, I was amazed at how many more developers Citrix had devoted to TS technology than Microsoft itself (which only had a fraction). I have not seen any numbers on Hyper-V developers, but my guess is that the comparison would be similar. While small compared to Microsoft, vSphere is still a sizeable company and puts all its resources behind virtualization. The magnitude is shown the 1,000 + engineers devoted just to the development of vSphere 4 over 3 years.

So features like VMDirectPath - how many different hardware models does that support? And how many are still experimental? And how many "enterprise" features do you have to turn off to use it?
Hyper-V R2 has supported the Intel VDq functionality since it released, so it's got half what VMDirectPath does out of the box.
And in terms of parent partition - where does IO go through if you're not using VMDirectPath (which most people aren't)? It goes via the hypervisor layer right? Just like going through the parent partition...
