description: 'In the interest of having this information somewhere handy: Firstly, to successfully install VirtualBox Guest Additions within a server based image: sudo apt-get install dkms build-essential linux-headers-`uname -r` I discovered that if you clone an ubuntu server based image, networking stops functioning in the clone. The reason for this is that the new Machine assigns a new MAC address to the NIC. So the Udev rules think it''s a new card, and assign it a new device id, like eth1, or eth2, etc. To prevent this from happening, in your base image, edit /lib/udev/rules.d/75-persistent-net-generator.rules Search for ''xen'', and you''ll see a block about ignoring the Xen virtual interfaces. Add the following below it: # ignore VirtualBox virtual interfaces ATTR{address}=="08:00:27:*", GOTO="persistent_net_generator_end" Save it, and then remove the file /etc/udev/rules.d/70-persistent-net.rules. Do the same thing in any cloned images with broken networking, and reboot the VMs.'
