Wild stab in the dark: Perhaps things have remembered the mac address of the original (automatically added) device as eth0 and so the virtio device has been renamed out of the way, meaning that /etc/network/interfaces's references to eth0 don't work? Does "ifconfig -a" (as root) show the virtio device with some name other than eth0? If so then you might need to edit /etc/udev/rules.d/70-persistent-net.rules to cause it to forget the old device.
