Sorry I missed that there were two of you with first name of John.

As I asked John Alberts, did you do a yum update or fresh install to get 
to 5.3?

Yeah I remember a thread on this.  I haven't redone a vhashify for 
awhile.  Of course I'm currently only running about 20 some odd guests

unification of the whole server the 30% (maybe more -- it was a long 
time ago) recovered space was impressive.
