I was trying to test the new networking layout and provision a rhel7.2 host with one primary and one provisioning interface. Primary interface is defined on static subnet(192.168.110.x). So I created alias and vlan interfaces on same subnet. Host was provisioned successfully but when I checked the interfaces and found only eth1 and eth0.

Later, I checked the config files and looks like networking snippet is creating config files with incorrect device name like:
ifcfg-:0 (for alias interface)
and ifcfg-.1(for vlan)

Please see the attached screenshot that shows the config files with incorrect DEVICE name. Also ENC output .
