We have used virtual machines for trying out new things (including new versions of operating systems) with great success. In fact, all our current intranet infrastructure (FAI, local mirrors, DCHP, DNS, LDAP, etc) runs from an array of virtual machines, distributed between two physical computers. This makes it easier to upgrade any service one by one, without major interruptions and without need for a separate box for every experiment. The underlying OS on the physical hardware is Debian squeeze, with 3.2 kernel from wheezy and KVM 1.0 from backports. I guess you can use any reasonably modern distribution and virtualization scheme since very little needs to be installed beyond a basic system and the virualization software. Setting up the virtual networking in the underlying machine may be a bit complicated if you have not done this before and need to run things like, eg, DHCP from the VM. However, once this is mastered, quite amazing things become possible, such as different VMs on different subnets, VMs with multiple (virtual) net cards, all running on a physical computer with a single Ethernet cable connected to a smart switch.
