[vbox-dev] eth0 not found in vbox guest OS

[JD]

After struggling with a lot of delays in obtaining the Fedora-Unity-8 DVD
iso image, finally installed and upgraded.
Booted it in vbox. All is working (so far) except
for a couple of problems:

1. eth0 not found - so it could not  bring up net.
2. When I go to full screen mode, the gnome desktop
   remains the same size as the small window.
   I re-configured it to the following xorg.conf
   and restarted (logged out and logged back in - to no avail:
