I also have found out that trying to change the media type to 10BaseT
with the 'media' flag in ifconfig causes the virtual machine to crash.
Maybe it just doesn't want to work correctly. I was going to test out
some network tools in a vm before actually configuring a machine to put
to the job doing it. But I guess I may just have to bite the bullet and
do it on a machine instead of using vmware. Which was my first thought
and it was out of my control at the time.
