I could not find a General forum section to ask my question so I will be send it here.

I want to know is there any book available which talks about different Hypervisor brands and specification in detail.
I am talking about a serious study not just comparing the features.

Thanks in advance and I hope in future a forum for general discussion regarding technical info of virtualization be available.

This is a bit old, but does it reflect what you're looking for?

Thanks Dave, I also search a little bit more and found this website:

As you said the comparisons are out dated but it's good for my purpose
