 +===== Copying of virtual machines =====
 +When copying virtual machines, it may be that a new Ethernet device with a new MAC address is created. If the Ethernet device gets a new name (eth2 ...), you have to add ''​auto''​ to the name of the interface in the file ''​etc/​network/​interfaces''​ (e.g., ''​auto eth2''​). Then the service ''​networking''​ must be restarted (''​sudo service networking restart''​).
 +Alternatively,​ you can edit the file ''/​etc/​udev/​rules.d/​70-persistent-net.rules''​ and assign the MAC to the eth0 device.
