About this OpenAFS in VM, I tried a small experiment some time ago
and I had some issues...
Basically there are two approaches to virtualization:
* each VM gets its own "public" IP address (practically it is just
like other hosts on the same LAN); in this case I have no doubts that
OpenAFS works flawlessly, minus the performance issues;
* the host has a single IP, and the VM's get a "private" IP
address, that is NAT-ed; in this case I remember I had issues with
properly configuring OpenAFS to handle such a scenario;
Could someone comment on his success / in-success in the second
NAT-ed scenario? I remember I gave up and just moved the OpenAFS on
the host. (I remember that 2-3 years ago there was some sketchy
documentation on this, but I haven't checked lately...)
