It's quite hard to ensure this.  On my server I start the guests in a
known order, with extra sleeps between the core guests (NFS, mail,
DNS) and the rest.  But there could still be a case where a guest has
to do an fsck or whatever where the services wouldn't be up by the
time the other guests start.  The next step beyond that is to start
the NFS guest and test that the NFS service is responding before
starting the other guests.  I don't know of anything you can download
which actually does this though.

Rich.
