Public bug reported: Binary package hint: udev
A cloned Ubuntu server will be assigned a different set of network interface names, and unless you manually change the names in the appropriate config file (i.e. /etc/udev/rules.d/70-persistent-net.rules, or /etc/iftab) and reboot, the cloned machine will be unable to connect to the network. Suspect at Ubuntu Forum (http://ubuntuforums.org/archive/index.php/t-1045715.html) is that the copied disk (/machine) already has a udev rule for eth0, with the MAC address of the original nic. The new machine's nic has a new nic with a different MAC, so udev rule generator adds a new line with eth1 for the new MAC, and consequently the nic will come up as eth1, even though "eth0" (the original MAC) is no longer present in the system. The 'old' eth0 rule should be deleted as the nic with the old MAC is no longer present in the system. This error is lasting from Ubuntu 7.10 to 9.10, and pops up in every hypervisor from vmware to KVM.
