Hi all,

I have a server onto which I have installed Ubuntu server, configured with 2 NIC (eth0 and eth1), each on a separate network:

Code:
eth0      Link encap:Ethernet  HWaddr 00:9c:02:a8:41:02  
          inet addr:192.168.1.3  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::29c:2ff:fea8:4102/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

Everything works fine there, now on this server, I have installed a virtual machine using VBox to install a Virtual-UbuntuServer, with 2 virtual NICs (let's call them v_eth0 and v_eth1)

And I have bridge them to their respective "real" NIC on the real server

Code:
NIC 1:           MAC: 08002731D119, Attachment: Bridged Interface 'eth0', Cable connected: on, Trace: off (file: none), Type: Am79C973, Reported speed: 0 Mbps, Boot priority: 0, Promisc Policy: deny, Bandwidth group: none
NIC 2:           MAC: 080027A6133A, Attachment: Bridged Interface 'eth1', Cable connected: on, Trace: off (file: none), Type: Am79C973, Reported speed: 0 Mbps, Boot priority: 0, Promisc Policy: deny, Bandwidth group: none
When I connect to the virtual machine, I can clearly see the two virtual adapters (using lshw -c network)

For simplifity, I have configured both adapters with dhcp but I can't seem to start eth1.

/etc/network/interfaces
Code:
# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

#Linux network
auto eth1
iface eth1 inet dhcp
result of ifconfig:
Code:

I have looked in the logs for any error related to eth1 but only found :
Code:
Jan  4 05:42:35 redmine kernel: [   10.590540] pcnet32: eth1: registered as PCnet/FAST III 79C973
Jan  4 05:42:35 redmine kernel: [   12.249245] ADDRCONF(NETDEV_UP): eth1: link is not ready
Jan  4 05:42:36 redmine kernel: [   12.571919] pcnet32 0000:00:08.0: eth1: link up, 100Mbps, full-duplex
I don't know what I am missing at this point, any help would be greatly appreciated. Sorry for the lengthy post but I'm trying to get as much information upfront.
