It might be, that the vmware interface does not trigger the creation
of a persistent rule. Network interfaces need to be created by a
"driver", be backed by a "bus".

Look a the devpath of the device and it will tell you the parent devices:
  /sys/class/net/eth0 -> ../../devices/pci0000:00/[...]/net/eth0
which means, that it's backed by a PCI device, and therefore a rule
will be created. Maybe the vmware interface is a virtual one.
