Try the 'lspci' command; on a virtual machine you'll typically see a bunch of devices that are obviously virtual (e.g. vendor is VMWare or such).

I usually use

dmidecode --type 1

For scripting you might try

dmidecode -s system-manufacturer

Often uname -a will display information that gives you a hint - references to Xen will tell you that you are in that type of virtual machine.
