Huh. Well, sorry for coming late to the party, but I teach CIS126DL at
GatewayCC, and speaking as a user (NOT as a representative of
Gateway!!!), I say:
The students must install CentOS, Ubuntu, and OpenSuSE on 'a machine'.
they can use a real machine, or they can use VirtualBox or VMWare. I
push them pretty strongly towards VirtualBox.
Most of them are using VBox under Windows, but my personal machine is
Linux Mint, and it runs MANY virtual machine instances (not just the 3
the students need to run), and I've never had any real problems - and as
far as I can tell the only real problems the students have is getting
virtualization enabled on their computers so that VBox works at all
(oh, and selecting the correct 'bitness' of the OS to install, but
that's a different kettle of fish).
Now, true, we're not trying to use anything other than NAT to get out to
the internet, but I personally have done some 'amusing' things,
sometimes with SSH, sometimes with multiple ethernet adapters, for other
cases. I've got a friend set up with Windows in VBox under Linux (Mint)
where the virtual machine shows up on his internal network - I don't
recall that being very hard.
Just my $0.02 worth.
Now, if you want to talk 'mess', let's talk about these stupid laptops
with multiple video adapters (for example, my Alienware) and trying to
hot-plug an external HDMI monitor! Gag. I did, however, discover a
workaround - fire up the monitor control app and turn off the laptop
monitor then turn it back on - now both displays work! Yes, extreme
rabbit trail! If you want to follow that rabbit, PLEASE start a new
subject!!!!!!!
