Networking VirtualBox – How to Fix Broken Networking in Cloned Virtual Machines


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.

Best Answer

There are udev rules preventing the new interface from being brought up.

In the Master machine, just delete them before you clone the new machines:

sudo rm -f /etc/udev/rules.d/70-persistent-net.rules
