I'm cross-posting this from the Kerberos mailing list since this is 
useful information for people running O/S's on top of VMWare and people 
come here for time issues.

it's a good idea, but be careful with the time synchronization.
Some guest OS consistently run more slowly or more quickly than real
world time. The reason that caused the slowing time inside guest system
is because of that the guest clock frequency is setting too high than
the host OS can offer.

And if you have a time problem Kerberos can't work properly, specially
the ticket manager.

If yours guest OS is Linux you have a workaround on the vmware's web
site :

if you want use FreeBSD check this link , but it's in French sorry,
maybe it can help :
