Windows 7 virtual machine on Mac SSD. Defrag, or not?

I'm running Parallels and a Windows 7 virtual machine on a MacBook Pro with an SSD (solid-state hard drive, the kind that doesn't have spinning platters).

Should I disable Windows 7's automatic scheduled disk defragmentation in the virtual machine, since I've read that defragmentation is counterproductive on SSDs, being something designed only for spinning hard drives? I know I'm running Windows 7 in a virtual machine on a computer with an SSD, but I worry that my Windows 7 installation through Parallels does not sense that and does not configure itself accordingly.

Virtual machine is running on the virtual hard drive. (Unless it is Boot Camp) - defray should work fine and should not affect the SSD drive anyhow.
 
Virtual Defrag?

Why do I need to defrag a virtual hard-drive in Parrells Windows 7 pro on my iMac Lion. Would defraging occur on the actual hard drive hosting it on the Mac?
Should one do a disk clean up and defrag at all in Windows if its Virtual on the Mac ??? this is so unclear to me.
