After restoring a snapshot to a new machine, you may\u00a0encounter issues caused by the MAC address<\/strong>\u00a0of the network adapter changing. Usually, when the network adapter changes the operating system will create a new network adapter for it. You’d typically see the network adapter on ‘eth1’ (or eth2 if you had private networking enabled).<\/p>\n
