If you’re a person who is been using HYPER-V and wanted to test it in your test lab you’ll know converting one of your live machine to virtual machine is a great thing. All this time if you’re stick to Microsoft tools then you have to buy SCVMM to do this conversion part. (Price tag is high!)
Alternatively you have the option of buying third party tools but it may not in your favor list since if you’re doing testing. There are few free tools as well but it won’t do the job of converting the physical pc on the fly.
Finally one person at Microsoft (Mark Russinovich) has given a consideration for this and released a tool for that.
Tool itself has been name as Disk2vhd. You can download it from the sysinternals.com web site which is part of Microsoft cooperation. Usage of this tool is very simple and once converted the vhd can be run on HYPER-V , virtual PC or attach to windows 7 or Windows 2008 as a HDD.
