Hyper-V Program Manager
Yesterday I posted about how Windows 8.1 / Windows Server 2012 R2 allow you to export a running virtual machine. This is also available when using SCVMM 2012 R2.
Here you can now clone a running virtual machine. When you clone the virtual machine you can either store it in your virtual machine library, or you can immediately deploy it to a Hyper-V server in your environment.
