Hi Larry,

As a valuable community member - please feel free to edit the documentation for 
CentOS7 (you can do it all via GitHub, from the link for CentOS7 guide), and 
include somewhere the fact that NetworkManager needs to be disabled (copy/paste 
the commands needed) - this will help future novice users get it up and running 
from the first time.

Kind regards,
Andrija

Subject: Re: Network Bridge - error

Hi,

Successfully configured using:

CentOS 6
http://docs.cloudstack.apache.org/en/4.11.2.0/quickinstallationguide/qig.html
but needs #yum install epel-release
before #yum install mysql-connector-python

And

CentOS 7
https://github.com/apache/cloudstack-documentation/blob/master/source/quickinstallationguide/qig.rst
but needs to disable NetworkManager


Thx...

Currently, learning how to use.
