What is the best method to defrag HyperV virtual machines?

From what I have read it is as simple as defragging the guest os using the native defrag tool in Windows, then degragging the host machine.

Is this accurate?

That is correct you must think of the VM as a physical install the OS is still going to see the hard drive fragemented even though it is just a file so you need to defrag within the Guest OS and the host OS.

Thanks.  One follow up question if you dont mind.

The virtual hard drisk (VHD) files are located on a Dell Powervault SAN.
Would there be any special consideration needed when defragging files on a SAN?

Nope this is all OS nothing to do with hardware. Defragging only moves files on a hard disk so the OS can access faster.
