To finish the KVM series (part 1 and part 2), this last part will show what has to be done to have another virtual machine up&running. This assumes you're using some of the newer Linux distros with udev enabled. The example is for Debian, I guess it's very similar on others.

Let's assume you have your first VM all setup, with IDS running and everything configured the way you wanted. Then you want to setup another one, almost identical (to play with HDR for example), with only minimum necessary config changes, both on OS and in IDS.

Can't be easier: just shut down your VM to save a stable state and copy the image.
