Hi,

I have been trying to configure my host machine (ubuntu) with a bridged mode.

My /etc/network/interfaces file looks like this:

auto eth0
iface eth0 inet manual
auto br0
iface br0 inet dhcp
bridge_ports eth0 vbox0 vbox1 vbox2
auto lo
iface lo inet loopback

My /etc/vbox/interfaces file looks like that:

vbox0 sabrina br0
vbox1 sabrina br0
vbox2 sabrina br0


if I run the command:
brctl show

I get:
root@dellb807:/etc/network# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.0022190eaf71 no eth0
vbox0
vbox1
vbox2


Then, I launched VirtuallBox and I configured the "network" parameter of the virtual machine with "host interface" and vbox0 for instance.
After starting the virtual machine, the internet connection does not work and I do not know how to assign a new IP adress to that machine.

A note:

root@dellb807:/etc/network# sudo /etc/init.d/virtualbox-ose restart
* Shutting down VirtualBox host networking... [ OK ]
* Starting VirtualBox host networking... Warning - failed to add interface vbox0 to the bridge br0
Warning - failed to add interface vbox1 to the bridge br0
Warning - failed to add interface vbox1 to the bridge br0

I have warnings that the vbox0.. were not added to the bridge.

Would anyone have an idea of the problem?

Thank you very much in advance.

Sabrina.

You shouldn't add vbox virtual interfaces to bridge at this stage. They are added later on by

Starting with VB 2.1 networking became even easier: you don't need a bridge. You simply select real host interface (eth0). You do need to install some linux tools, this is described in VB documentation.
