I've set up a virtual machine configured with bridge networking. After making eight clones of it, the new machines can't connect to the network.
I've instructed VirtualBox to re-generate the machines' mac-addresses.
In the Master machine, just delete them before you clone the new machines:
I encountered the same problem on a previous version of VirtualBox and I read somewhere that there was a bug which rendered the "generate new MAC address" tick box useless.
I'm now using Ubuntu 12.04 with VirtualBox 4.2.10. I noticed now that when I created the clone, there was no tick box to "generate new MAC address."
This gave me some problems even if I deleted 70-persistent-net.rules because the system would automatically generate the file on startup with the same MAC address as the original, which made it fail to connect.
But I discovered that in VirtualBox Manager, you can select the clone, go to Settings>Networking>Advanced and generate a new MAC address by ticking the box.
So what I did was to delete 70-persistent-net.rules first, shut down, generate new MAC address and start again, and now it works.
Alternatively, you can delete the file first before you clone. Then generate MAC address, then start the clone. That ought to work as well.
I am building parallel computing environment that needs interconnection between the virtual machine through ip network.
I think there is something related to the re-generate the machines' mac-addresses. I had faced the similar problem before.
The original virtual machine has

That is due to MAC regeneration that in the clone machine, there are

So, good luck guys!
Refresh your MAC address using Virtual Box machine settings and remove the kernel’s networking interface rules file so that it can be regenerated:
It will work for your clone VM.
I deleted 70-persitent-net.rules file but it wasn't re-created after reboot. Then, re-installing guest additions module and rebooting the VM worked for me.
I have problem with same ip-address after cloning 3 VMs with Virtual BOX (4.3). SO I have power off the machines and regenerated new mac address and restarted it worked for me.
steps => switch off the cloned VM and then settings => network => advanced => click on refresh MAC address => clik OK. then start VM.
I was dealing with the same problem for months and today I decided I would find a better fix. Here is what I did on the machine I was using as a Template.
For good administration practices back up both files before editing.
You have two offending/target files:
This will work for a
Delete the MAC Address line:
Delete the file
You can now clone your box and every clone will correctly deploy and display eth0.
If you do not use a template, you may complete these procedures on the actual VM just remember to re-initialize the NIC your in the VM software before you restart the machine.
