Before you do the move into a VM, check that your VM is up to the
number of IO/sec that an AFS server can make. I know that su.se
moved all there AFS servers into a VM solution and then out again
because of performace issues under load from many concurrent users.

I have not tried to move my AFS servers into VM because I don't
have the time to gamble with that sort of things.
