Simple way of putting a VM on a LAN

[Bill Davidsen <davidsen@tmr.com>]

I seem to be missing the "right way" to put a VM on the LAN such that it 
appears to really be a machine on the LAN. This is a requirement for 
being able to deploy internal servers as needed.

For instance, consider a DNS server or outbound mailer at IP 10.x.y.z 
and how to do that with a VM. Current I have not found a way other than 
putting the IP on as an alias, like eth0:1, setting up a tunnel using a 
bunch of stuff from Debian, plugging in a set of moderately complex 
iptables rules, starting the VM using a bunch of obscure -nic options 
unreleated to the actual IP to be provided, and generally a ton of 
complexity to install and remove.

I often want to provide momentary service not requiring preserving a lot 
of state, like mailers, DNS, etc. Surely there's a better way?
