I saw it worked but was different to what I am used to. So I installed
it to a USB drive and plugged it into another computer. And I had no
internet connection. Dead! But the instructions on the wiki page, that
Phill asked me to edit, there was a solution. Now it looks and feels and
works as usual.

I think it hardcoded the connection to a MAC address because I ran it in
a machine with two ethernet ports and it asked which one to use (it did
not check which one was connected (only one of them was connected).

It is probably enough to run in a VM, but remember to subtract, what is
subtracted from RAM in a typical real machine (256 ---> 242) MB.

I wouldn't write that on a wiki page, but we must be able to mention it
in an internal discussion. But with that in mind, we might avoid to
mention the possibility to run Lubuntu below 256 MB RAM.

I'm looking forward to it :-)
