Nice to have.

A good starting point.   I have been doing something similar - create
a bunch of image templates

At present, we have
1. A portable desktop appliance - basically a  LXDE desktop install
that can be dd'd onto a 4GB pen drive.
2. Min. server with ssh and ntp enabled.
3. LAMP  (PHP, Python, MySQL, postgreSQL) for web development platform.
4. Desktop KDE with KDM supporting XDMCP for a quick demo of remote desktop
5. Desktop with Qt SDK
6. Desktop with GTK SDK
7. Server with postfix+dovecot+roundcube for email server deployment
8. DB server (MySQL, postgreSQL) for production deployment.

The above is in a mix of CentOS, Debian, and Ubuntu base.  Whenever
anyone needs a pristine base, I copy the appropriate image file, boot
it with virt-manager, change the network parameters, hostname etc. and
hand it over to the developer/sysadmin.

Take a look at the  turnkeylinux.org appliances to see what others are doing.

I vote for the sudo approach.  One can always do "sudo su -" as that
user and would be equivalent to ssh root at somehost.

I vote for a post login message.  The VM sysadmin has more control.

Keep us posted on the progress.
