Fair enough, not that any of the systems are heavily loaded.

Except the web server bit that my partner uses, break that and she will
complain!

Okay, I'm happy with the idea in principle, mostly as a learning exercise.
I've some follow up questions:
1) It's all going to take place on a private 192.168 network, so I can assign
each VM their own IP address, and the host system will do the routing?
2) On most of the VMs I won't need any real user accounts per say. I normally
never login to any of my boxes a root, I almost always login as me then "sudo
foo" or "sudo su -" if I need to so admin stuff. How do you deal with admin
on the VM? Login as root?
3) Though they are all VMs on one real system, is it worth running up a NIS or
LDAP server to maintain users?
4) What kind of disk footprint will a Debian VM take up for something like an
externally accessibly SSH server? I gather Xen works well with LVM.

I guess that, if you're in Microsoft's shoes, it makes sense. If you
can't write software or protocols that can stably walk and chew gum,
program in a limit that prevents the user from telling it to do so.
