We are running AFS as both servers and clients under a combination of vmware
products.

We have 3 AFS servers running under ESXi.  Our student UNIX login servers
are also running under ESXI and are running the client.  Both have worked
flawlessly.  I am also running a fourth AFS server under VMWare fusion, and
its been running flawlessly as well (it was just tricky to have it startup
at boot).  We use VMWare workstation / fusion for a number of courses, and
each have AFS client installed.  Again, students use those in a variety of
abusive ways and it has worked fine.

We *were* using 8.10 on our servers - so I wasn't using 8.04.  You may want
to look to ensure that your cache settings on the clients aren't set to use
memory, that can make things pretty slow - esp. since VMWare places game
with the guest's physical memory and how its actually allocated.  My
intuition is that the memory cache would reduce performance for the virtual
machine.

We are running an Ubuntu server &quot;Ubuntu 8.04.4 LTS&quot; with the Open=

How many others are running AFS clients on VMware guests? Any issues or sug=
gestions on troubleshooting this? 
The VMWare is version 4.0.
