Description of problem:

After finish with RHVH-4.0-20160817.1 installation, the nameserver and search entries in /etc/resolv.conf file won't exist.
This would be noticed while trying to ping/resolve a FQDN and also while trying to register the RHVH through RHSM

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

RHVH-4.0-20160817.1-RHVH-x86_64-dvd1.iso from download access portal

How reproducible:
100%

Steps to Reproduce:
1. Install a new RHVH with GA ISO from portal
2. During installation, configure network and define a DNS and a search domain
3. Complete the installation and reboot
4. Check for /etc/resolv.conf content and/or try ping/resolve a URL/host

Actual results:
nameserver and search definitions in /etc/resolv.conf are missing after RHVH installation

~~~
[root@rhvh40-3 ~]# cat /etc/resolv.conf 

[root@rhvh40-3 ~]# dig www.redhat.com

; <<>> DiG 9.9.4-RedHat-9.9.4-29.el7_2.3 <<>> www.redhat.com
;; global options: +cmd

;; connection timed out; no servers could be reached
[root@rhvh40-3 ~]# ping  www.redhat.com
ping: unknown host www.redhat.com

~~~

Expected results:
The entries should remain configured as defined during installation

Additional note:

Simply by adding them into /etc/resolv.conf fixes the problem

Also, initially, before adding the host into RHVM and create the ovirtmgmt bridge, the ifcfg-eth0 file has the correct information

ifcfg-eth0:
===========
DEVICE="eth0"
ONBOOT="yes"
IPADDR="192.168.122.136"
PREFIX="24"
GATEWAY="192.168.122.1"
