Find out if the OS is running in a virtual environment

I don't trust my host as far as I can throw them. We are about to move, but I have got this nagging doubt that rather than being on the dedicated machine that we ordered I'm actually on a virtualised machine.

How would I go about proving this one way or the other?

For VMWare at least, either have a look at the network adapter type (it should say VMWare) or get the MAC address of the NIC and go here to look up the vendor.

Assume your guest OS is Linux, you can do dmidecode -s system-manufacturer. In the case of VMWare it will return VMware, Inc..
