Man this sucks, I didn't know this White Paper existed. I have been working on documenting AD on VM's for both VS2005 and VMware ESX.
You might be experiencing the fragmentation due to using the feature that dynamically expands the volume as it uses disk space. You might try just mapping raw disk space.

What VM software were you using? Did you "hard" reboot the VMs? You were experiencing actual corruption issues? I guess I'm a little skeptical. Do you remember the nature of the corruptions? Were there AD JET level recovery issues? If you still have any of the event logs, I'd be curious to know what JET and AD events you felt indicated corruption, and the cause of the non-booting DC, get this via event log in DSRM (DS Restore Mode). I ask, because correctness (i.e. no corruption) should not be sacraficed b/c the underlying host has a fragmented FS. It should just be slow ...
