I have the following setup:

  • Windows host running virtualbox
  • Ubuntu server as a guest

I've enabled a second networking interface in Virtualbox - a bridged one - so I can connect to the instance via ssh, http etc

(note: this has always worked using ubuntu desktop using the GUI to configure networking, but now I'm using ubuntu server and doing it manually in ubuntu)

This is roughly what I do:

I have the instance running and I can, eg. ping stackoverflow.com and I get an IP address I stop the server, enable the second adapter in virtualbox I start the instance again I can see that the interface is listed using ifconfig -a I open /etc/network/interfaces and add the eth1 controller, so my interfaces file looks like this:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet dhcp

and when I restart using /etc/init.d/networking restart everything seems to work - ie. ifconfig gives me this:

eth0  Link encap:Ethernet  HWaddr 08:00:27:ad:75:94
      inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0

And I can connect to the instance using ssh, so networking is working..

however, DNS resolving seems to be not working, because when I ping any website (eg. stackoverflow.com) it just times out..

I checked /etc/resolv.conf and everything looks fine (in fact, looks the same as the one on my ubuntu desktop instance.

Any ideas?
