VMWARE are kings of the virtualization world. In a distant second place is Microsoft with Hyper-V. In order to kickstart IT Professionals into learning Hyper-V they offer a great little online course here; Microsoft Hyper-V Learning
This is all done via the Microsoft Virtual Academy - an online learning resource.
In addition to the learning you can, at time of writing, get an exam voucher to do the associated Microsoft exam for free. This is $150 (£99) worth of exam credit.
So you can potentially get a real qualification out of the course. I thought it was great and invaluable to understand Hyper-V.
