Hyperv VHD size

I have Windows 2008 R2 wit HyperV.
When my virtual of Windows 2008 R2 is shut down the folder that stores the VHD (and other related files) is 100GB.
When it is running the folder that stores the VHD (and other related files) is 200GB

Wh does the size double?

Hi,

Do you have many (redundant) snapshots of the vm? If yes then i would suggest removing those snapshots before powering on the vm.

how much memory do you use for the VM, Hyper-V creates a .bin file that contains the memory of the virtual machine. The file is deleted when the VM is stopped.

This blog post might help you identify where the vm stores information: http://blogs.msdn.com/b/virtual_pc_guy/archive/2010/03/10/understanding-where-your-virtual-machine-files-are-hyper-v.aspx
