Most times when using a Utopia demo you want the demo virtual machines
to have internet access as well as being able to communicate with each
other. If your demo is small enough to fit onto one physical host
providing the vm's with internet is easy: just set the virtual network
to NAT. But what if you want to span the vm's across multiple hosts,
either because the demo is large or because you want to optimise
performance?
Whenever you need a vm on host 1 to talk to another vm on host 2 you
need to use VMware's Bridged Mode for networking, and then of course you
lose NAT's ability to provide seamless internet access to the vm's. In
the past we provided a workaround for this that involved you manually
reconfiguring one of the hosts to act as the default route and gateway
for internet traffic, but this was complex to do.
Now, with this new router vm, we are giving you what is in effect an
internet router virtual appliance for Utopia systems. This tiny vm
requires only 64Mb of RAM to run, but if you start it up in a bridged
Utopia demo all the vm's in that demo will instantly and automatically
get access to the internet via the physical interface of the host on
which the appliance is running.
In other words, just unzip it and fire it up. Job done.
