Can't obtain IP from DHCP on Ubuntu Desktop in bridged mode

[leonger]

Hello! I've just installed Ubuntu desktop 13.04 on a VM, but cannot get a network connection in bridged mode. It works fine with NAT, but I need to access this VM from other machines, so I am trying to make the bridged connection work. Here is what I get when running ifconfig:

Code: Select all

eth1      Link encap:Ethernet  HWaddr 08:00:27:ea:1f:42  
          inet6 addr: fe80::a00:27ff:feea:1f42/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          RX bytes:22751 (22.7 KB)  TX bytes:17272 (17.2 KB)

          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:47 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:0 
          RX bytes:4642 (4.6 KB)  TX bytes:4642 (4.6 KB)

I've seen a number of posts on this issue and tried the recommended solutions such as assigning a new MAC to this box and removing /etc/udev/rules.d/70-persistent-net.rules files, all to no avail.
Anyone can suggest anything else?
Thanks in advance!

What is the output of :

Code: Select all

sudo cat /etc/network/interfaces

[leonger]

Code: Select all

Seems like a guest config issue, but I never use Ubuntu in desktop mode so I am not 100% sure this is used. Regardless, make sure your network config is right and that every firewall is disabled, both software & hardware on every machine (guest & host).

[Perryg]

I would be interested in seeing the ifconfig -a results as well as:

From the hosts terminal/command window type VBoxManage showvminfo <VM Name> --details and post here. Replace <VM Name> with the actual name of the VM. Use " " if the name has a space in it.

Note if the host is Windows you need to be in the directory that has VBoxManage.exe for the command to work.

Finally VBoxManage list bridgedifs from the hosts terminal

[leonger]

Thanks for looking into it, guys!

Ifconfig output from the guest is in the original post.

Here is showvminfo output from Win-7 host:

And BTW, 2 Ubuntu server VMs on the same host work just fine under bridged connection, so I suspect this is something with guest setup for the desktop...

[Perryg]

Ifconfig output from the guest is in the original post.

But I asked for ifconfig -a are you saying that it is the same?

post the file /etc/udev/rules.d/70-persistent-net.rules

[leonger]

Yep, the same thing:

You can see your issue above. You have two assigned adapters and only one active. In this scenario the guest is going to expect to use eht0 and it is not attached to the working connection.

All you should need to do is completely delete /etc/udev/rules.d/70-persistent-net.rules and reboot the guest. It should then detect the right MAC address and assign it to eth0.

[leonger]

Did that - no success.
Removed the file again, shut down guest, refreshed MAC address, started guest - no success either

[Perryg]

Does it still say eth1?

[leonger]

no, it says eth0:
