Can our networks be set up using a series of VM's?

Is this the future of our networks?

- Pre-configured LDAP VM.  Script to edit the domain name used, tools for
managing it.
- Pre-configured LAN Services VM.  Gets some basic config from LDAP, tools
for managing DNS/NFS/CUPS/etc
- Pre-configured email VM.  Setup uses defaults set in LDAP VM, users
managed via LDAP
- Pre-configured MySQL Database server VM. Setup uses defaults set in LDAP
VM.  Managed via LDAP
- Pre-configured RBDL server VM (one for each arch?).  Clients and server
users controlled via LDAP
- Pre-configured LTSP server.  Setup uses defaults set in LDAP VM.  Managed
via LDAP
- Pre-configured KOHA server.  Setup uses defaults set in LAN VM.  Managed
via LDAP

This sets up an ecosystem whereby VM's can be moved around as needed. you
rely on one or two VM's (LDAP and LAN services) that would be built on LTS
builds.  Other services, being VM's, can be updated as needed.

Apps can be added as appliances, using remote X sessions.  Resource hungry
apps can be done as local VM's on clients.

Thoughts?

There's a substantial performance hit for running in VMs. I could see it for specialized things like the LDAP server, although if ClearOS adds replication to theirs that runs out of the box, it might make more sense to run ClearOS on one server for most network services and home directories.
