Description Ganesh Kadam 2018-08-30 12:31:33 UTC 
Description of problem:

Cu is under the impression that the KVM guest image found at:
~~~
 https://access.redhat.com/downloads/content/69/ver=/rhel---7/7.5/x86_64/product-software 
~~~
should be ready to deploy in private KVM or 
OpenStack environment, without making any modifications.

But, currently, Cu sees an invalid DNS server entry for 192.168.122.1 in /etc/resolv.conf:
~~~
 cat /etc/resolv.conf
; Created by cloud-init on instance boot automatically, do not edit.
;
# Generated by NetworkManager
nameserver 192.168.122.1
nameserver 72.x.x.x
nameserver 72.x.x.x
~~~

Cu considering this as a flaw in the image, as it blocks deployment and causes network slowdowns.

Version-Release number of selected component (if applicable):
rhel 7.5 guest kvm image

Actual results:
Invalid dns entry present in rhel7.5 guest image

Expected results:
Remove the invalid DNS entry from rhel7.5 image
