installtion logs

Description of problem:

During the installation of RHEL 7.2, physical network interface is configured even when the vlan interface is defined in kickstart and had to manually up the VLAN after the first boot. 

Version-Release number of selected component (if applicable):
RHEL 7.2

How reproducible:

100%, the VLAN interface will not come up

Steps to Reproduce:
1. kickstart file used in reproducer:

anaconda logs seen during installation:

~~~
12:04:01,308 DEBUG anaconda: setting locale to: en_US.UTF-8
12:04:01,322 DEBUG anaconda: network: devices found ['eth0']
12:04:01,498 DEBUG anaconda: network: pre kickstart - adding connection for eth0.101

12:04:01,624 DEBUG anaconda: setOnboot: UnknownDeviceError('eth0.101', GLib.Error('GDBus.Error:org.freedesktop.NetworkManager.UnknownDevice: No device found for the requested iface.', 'g-io-error-quark', 36))
12:04:01,625 DEBUG anaconda: network: setting real kickstart ONBOOT value for devices ['eth0', 'eth0.101']
~~~

Actual results:

vlan interface not being activated. 

Expected results:

1. The interface eth0 had dhcp IP address during installation, as that is a primary device from where installation was carried out, the same settings will reflect on the base machine post installation.

2. the device eth0.101 should have been enabled as it was mentioned --onboot=yes, but it looked onboot=no.

3. After the installation, I did modify both the files /etc/sysconfig/network-scripts/ifcfg-eth0 and /etc/sysconfig/network-scripts/ifcfg-eth0.101.

4. The changes were as follows.

/etc/sysconfig/network-scripts/ifcfg-eth0 => onboot=no
/etc/sysconfig/network-scripts/ifcfg-eth0.101 => onboot=yes

5. Restarted the network service

        service network restart

The device eth0 got down and eth0.101 got up with proper configurations.
