Cloned VDI loses network settings

Post by **abcuser** » 17. Oct 2008, 08:54

Hi,
I use "VirtualBox 2.0.2 64-bit PUEL version" on "Ubuntu 8.04 64-bit" as host.

I created virtual guest of Windows XP SP3 32-bit, Ubuntu 8.04 32-bit Desktop and Ubuntu 8.04 32-bit Minimal install.
So far so good. Cloning VDIs of Windows XP and Ubuntu Desktop is without any problem. But cloning Ubuntu 8.04 Minimal is strange. Cloning is finished without any error displayed. But when starting guest there is no network available. If I execute ifconfig in original guest there I can see eth0 network card, but the same command in cloned guest there is only lo (loopback adapter), but no eth0. Very strange. Any idea what is wrong? Is it cloeing problem or something else?
Thanks,
Abcuser

udev assigns a new interface for any new MAC address, so you'll probably have eth0 (error, interface not found) and eth1 now.

edit /etc/udev/rules.d/70-persistent-net.rules - delete the eth0 line and change eth1 to eth0

Hi,
I have delete first line (eth0) and changed NAME="eth1" to NAME="eth0".
I rebooted computer and I still can't connect to network. Is there any thing I should do?

did you assign a new mac address to the cloned vdi?

otherwise could be a conflict.

also remove any mac address stuff from the guest network scripts.

And just to be sure, remove all the interfaces listed in the udev rules file. Reboot and you should have the proper interface listed as eth0.

@Sasquatch, thanks that is the very simple and working solution. I just delete whole content of file /etc/udev/rules.d/70-persistent-net.rules
and reboot computer. Ubuntu set network and it is working fine.
Thanks
