One day I was doing demo of all six MDOP products, and 5 minutes after demo my Hyper-V virtual machine suddenly paused and my screen froze. What’s the deal with that, I was asking myself? So if something similar happened to you, and you were asking yourself the same question, the answer lies within low disk space. Anyway free space on hard disk for your virtual machine must not be lower than 200 mb, and if it does your virtual machine goes into PAUSED CRITICAL state. So if you have important presentation and demo, check your free space, and check it after you start virtual machine.

Especially if you plan to demo application virtualization, and one of demo scenarios is installing and virtualizing big applications. Then your vhd file could become bigger and you could run out of free space. And you don’t want that happen to you during demo.
