Hi Ray,
I didn't mean to offend but you might have needed to invest some
effort into linux network configuration. Configuring a real Ubuntu
system is not that different of configuring it in VM. All you need
to do in VirtualBox is to set up IP/netmask in global settings as
well as IP range for VirtualBox DHCP server associated with .
Moreover, the default settings for vboxnet0 may work well for you,
so you just need to check what IP address your vboxnet0 interface
has. You can do it from OS X command line with 'ifconfig vboxnet0'
after you've started the VM. You don't need to bring up DHCP server
in VM, just configure Ethernet interface in VM (most probably eth0)
to obtain IP address automatically (which is the default, btw). You
can configure it via /etc/network/interfaces or via NetworkManager
applet in Gnome (there is a similar thing in KDE, but I don't know
the name, look for something resembling a network connection icon in
the tray area).
The idea of having a matrix is not feasible imho as there are way
too many operating systems and their flavors that can be run in VM.
Instead we are trying to have reasonable defaults so it would take
zero configuration if one doesn't need anything special. In your
case it means that if you boot Ubuntu live CD in VM it should be
able to obtain IP address automatically.
Can you send me your VirtualBox.xml, <machine>.xml as well as /etc/
network/interfaces from the guest in private mail? I may be able to
tell then why your guest cannot get IP from DHCP server.
Cheers,
Aleksey
I appreciate you willingness to help. It _is_ better when things just
work with zero extra configuration. The trick is having this work
_and_ having error recovery be obvious. One sets up automatic
procedues, but then when there is some problem, those procedures
obfuscate the problem. I have seen it a million times...
I will send some you some of this, off-list. Hopefully, we can report
back some good things after. And if I can find a wiki to update
somewhere with whatever info we find, I would feel a lot better. I
have less problems with slogging through mud when I can convince
myself that I am making it easier for the next person.

Instead of vboxnet0, which is the name of the interface, you need
to specify the name of the guest (VM) system, or its IP address if
the name is not in DNS. You can look up (or change) IP address in
global network settings (see below).
Ok. Well, I am not an expert on setting up linux systems. So, I
looked elsewhere on the net to find the bits I needed (I think) to
the /etc/network/interfaces file in the Ubuntu guest. And I turned
on (I think) the DHCP server in VB. And the guests still cannot see
anything to get an IP address from.
It seems as though the information problem here is a matrix. I am
running VB on platform X. I am trying to run guest OS Y. I am
trying to setup up network configuration Z. I have to do procedure
A on VB and procedure B on the guests. It seems as though the "open-
source-ish" way to do this would be that each of these would be on
a wiki. So I would look for an article entitled "Using VB on Mac OS
X to set up Ubuntu 9 guests with Host-only Networking."
Instead I find a web page (http://www.virtualbox.org/wiki/
User_HOWTOS) where "articles" are hosted after they are sent in?
That doesn't seem very interactive. The "User HOWTO" page seems to
cover only about 1/5 of the matrix here.
And I find a phpBB forum system. I moderate a forum system using
this for a commercial publisher. It is a PITA to use, there are
lots of redundant questioners with no answers to sort through, and
the search engine is crap. One might expect this from a commercial
publisher, but it does not seem very open-source.
This newtwork setup was pretty painless when I was using Parallels.
I guess I will have to go away and come back in a year or two,
again, and hope that VBox documentation is using open platforms and
the docs may actually be complete enough. We'll see.
In the VirtualBox graphical user interface, you can configure
all these items in
the global settings via “File” -> “Settings” ->
“Network”, which lists all host-only
networks which are presently in use.
On Mac it is a bit different: "VirtualBox" -> "Preferences",
"Network" tab.
Well, VB works on several platforms, and guests can be one of
several platforms. If the UI instructions cannot be correct for the
given platform, what is the point?
O well.
