I have installed rhel 6.6 minimal installation.
Since my system is not registered to Redhat, i cannot access the rhel repo. Hence, i created a local repo using the DVD-ISO image.

I have used the following steps:
Assuming that the iso dvd image is placed at /ISOs
1) mkdir -p /var/OSimage/Rhel6.6_x86_64
2) mount -o loop,ro /ISOs/rhel-server-6.6-x86_64-dvd.iso /var/OSimage/Rhel6.6_x86_64/
3) Add this in the /etc/fstab file : "/ISOs/rhel-server-6.6-x86_64-dvd.iso /var/OSimage/Rhel6.6_x86_64/ iso9660 loop,ro 0 0"
4) Created a Rhel-local.repo in the /etc/yum.repos.d/ file
whose contents are as under
[Rhel-local]
name=Rhel-Local repository created from ISO
baseurl=file:///var/OSimage/Rhel6.6_x86_64/Server
gpgcheck=0
enabled=1

Then, i did a yum repolist that gives the following O/p.
[root@rhel6-64bit yum.repos.d]# yum repolist
Loaded plugins: product-id, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
repo id repo name status
Rhel-local Rhel-Local repository created from ISO 3,785
epel Extra Packages for Enterprise Linux 6 - x86_64 11,831
repolist: 15,616
=====================

But even though i had opted for minimal installation, it gives me this when i run "yum update"

[root@rhel6-64bit yum.repos.d]# yum update
Loaded plugins: product-id, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Setting up Update Process
No Packages marked for Update
===================

My purpose for this is the installation of few packages like cloud-init, git, parted etc. But on doing the "yum install -y cloud-utils cloud-init parted git ".
I get the below error
-----
Error: Package: python-boto-2.38.0-1.el6.noarch (epel)

Can anyone suggest about how to correct this??
Any help shall be deeply appreciated

First question would be why are you using RH when you could be using Centos and have access to the repos?
You are aware that Centos is RH just re-branded right?

I have that issue before with laptops and Virtual machines. Sometime the network adapter is turned off no reason at all. Check and see if you NIC is enabled.

I know it sounds odd but have encounter the same thing after every reboot.

Yes, we can 'suggest you':

• PAY FOR Red Hat, which will get your system registered, and make the message go away
• Use CentOS for free, as lazydog suggested

It will definitely be simplest to just use Centos instead of RHEL.
Also, add https://wiki.centos.org/PackageManag...Yum/Priorities if you are going to add other repos eg EPEL.
