I hadn't considered vms with multiple nics and having them enumerated correctly might be worth more than fixing this issue.

On an existing vm with one interface, /etc/udev/rules.d/70-persistent-net.rules might be something like:

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM ... ATTR{address}=="00:50:56:80:68:23" ... NAME="eth0"

After a clone the file still has the previous line but also an additional line:

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM ... ATTR{address}=="00:50:56:80:13:f7" ... NAME="eth1"

So the result is there is still only one interface and it's eth1 but the rest of the networking configuration is looking for eth0.
