   Thanks for letting us know!  Does that mean that even the VMs with   
   dynamic drives are running close to the speed of a native install?   
      
   Also, are all the guest systems 32 bit?  I tried installing a 64-bit   
   guest, but VB said "VT-x/AMD-V hardware acceleration has been enabled,   
   but is not operational."
