Hi Darren,
Please check if DHCP server settings are right for vboxnet0. You'll
need to go to 'Preferences -> Network -> Edit (button with a
screwdriver) -> DHCP Server. Make sure vboxnet0's address and DHCP
lower-to-upper addresses are on the same net. If all the settings are
correct, please, check guest's network configuration for the 2nd NIC.
I assume you use the default way to configure the network in Karmic
server. Guest's /etc/networks/interfaces should have something like
this:
iface eth1 inet dhcp
Of course this is for the situation when the 2nd NIC is configured as
eth1. It may get another instance number if you have changed MAC
address of the adapter somewhere along the way.
If nothing helps please enable packet capture on the internal network
with 'VBoxManage modifyvm your_vm_name --nictrace2 on --nictracefile2
some_file_name' and send the resulting file to me in private mail. Do
not forget to turn it off later.
Cheers,
Aleksey

Hi Aleksy,
Well, here's the steps I did. I set up my guest Ubuntu Karmic
server. Install fine. I set Adapter 1 to be NAT. When I start the
guest OS, the NIC gets an IP address and it tunnels out fine. Later,
I add Adapter 2 as a host-only vboxnet0. For this adapter, I want to
ping it from my host and send traffic only between the host. When I
boot the guest OS, the 2nd NIC does NOT get an IP address. On the
host, however, the vboxnet0 nic comes up with an IP.
Now, if I swap adapter 1 and 2 and use my working NAT nic for
adapter 2. It does not get an IP. Its as if
it won't allow more than one nic.
I've not been able to get bridging to work at all either.
I have a laptop with a wlan0 nic and eth0 (not connected though).

Hi Darren,
VirtualBox supports up to eight NICs per guest. What exactly does
not work for you? You cannot ping the host from the guest? The
guest does not get IP address on the second NIC? Is the second NIC
up? Where do you connect the first NIC?
Regards,
Aleksey

Hey Fábio,
My laptop only has 1 physical network card on it.
But what I want is for my guest OS to use a "host-only" networking
and that
shouldn't require a physical card in the host OS, right? I want to
network
it with my host, which DOES get a vboxnet0 IP address and nic.
My understanding is the vbox device drivers for vboxnet0 will
emulate
a physical network and also the NIC in the guest OS. But it
doesn't seem to work.

I have no idea of what happening in your system but I can
affirmatively say to you, it works !!!
I have a system with 4 network cards, all configured in bridge
mode, all with different IP numbers and connected to different
networks, and ALL my 3 Virtualbox guests have full access to all
4 networks .
My host is Debian Lenny, my VBox is the latest present in SUN apt
repository .
After configured all 4 cards in bridge mode, all I needed to is
was create 3 new cards to all guests, configure it, and that's
all ...

Hi,
I've been trying for 4 days to get my ubuntu guest on my ubuntu
host to correctly bring up 2 network interfaces.
Only 1 ever comes up. Does VBox support multiple networks? The
second interface is host-only, but gets no IP
address. I've tried a variety of options with no success.
Thanks for any help.
Darren
