Description of problem:
Foreman discovery image currently will attempt to DHCP off the first NIC on the system and attempt to register with Foreman on that network. In a scenario where Foreman is listening on a non-primary, non-native VLAN interface, there should be a parameter such as fdi.register_interface that can be passed to the discovery image. The idea is that it would only bring up that specified interface and register to Foreman over it.

e.g.:

fdi.register_interface=eno2.1000

In this scenario Foreman is listening on the VLAN 1000 network.

In the current state with this scenario, the Foreman discovery image fails to boot and stops at a DRACUT prompt with the following errors:

ln: failed to create symbolic link '/run/initramfs/livedev' : File exists
device-mapper: create ioctl on live-rw failed: Device or resource busy
Command failed
device-mapper: create ioctl on live-base failed: Device or resource busy
Command failed
device-mapper: create ioctl on live-osimg-min failed: Device or resource
busy
Command failed
ln: failed to create symbolic link '/dev/root': File exists
Warning: Could not boot

However, adding this parameter allows the image to boot properly:

vlan=eno2.1000:eno2

Unfortunately, though the image boots and the discovery script runs, the primary interface eno1 is brought up and the Foreman server's hostname cannot be resolved and results in errors stating:

Could not send facts to Foreman: getaddrinfo: Name or service not known

bug 1108512 discusses this issue, but since the eno2.1000 interface is not up, setting foreman.url= to the Foreman server doesn't help.

I also tried the following parameters with no luck:

ip=::::eno1:off ip=::::eno2.1001:dhcp

I can manually log into the discovery image, down eno1 and bring up eno2.1000:

ifdown eno1
ip link add link eno2 name eno2.1001 type vlan id 1001
ip link set dev eno2.1001 up
dhclient eno2.1001

Then I need to kill the discovery script and it will restart. The image will now register with Foreman. However, it displays the following error after a few minutes and repeats it over and over:

Response from Foreman 500: { "error": {"message":"address family must be specified"}

In RHEL OSP Installer, when I try to associate this host with a host group, I get the following error:
