Using Foreman 1.8rc3 and multiple nics:
eth0:
DNS Name = servername
Checked items = Primary
Network = Static

eth1:
DNS Name = servername-dhcp
Checked items = Manged, Provisioning
Network = DHCP

When 'submit' is clicked, VMware creates the vm with the name 'servername-dhcp'. I'd expect the VM name to be the the same as the "Primary" interface.

The host is created with the correct "Primary" interface name in Foreman, 'servername'. The yaml output from the provisioned host reflects the correct settings:
