We have AFS server VMs on VMware whose vice partitions are vmdk files on
an NFS network file system, and they're usable.  They're slow (we're using
them to store old archival volumes that don't get much traffic), but
they're still usable.  Given that, if you did something slightly less
awful in terms of performance, I suspect you could run a real file server
that way.

I wouldn't use this to serve our hot volumes, but it's not a bad place to
park stuff that doesn't get heavy traffic.
