Again, I recommend Diskeeper.
Full Disclosure, I have some free licenses from them for testing. No other
compensation is involved.

So, as far as I get it, defragging from inside a VM (sorry, I forgot
to specify my .vhd are alle fixed size ones) is good and improves
performance of the VM itself, BUT you have to use a defrag tool which
is aware of being defragging a VM and not a physical one.
