Install openswitch and init a br-int bridge
yum -y install make gcc openssl-devel autoconf automake rpm-build redhat-rpm-config python-devel openssl-devel kernel-devel kernel-debug-devel libtool wget
mkdir -p ~/rpmbuild/SOURCES
wget http://openvswitch.org/releases/openvswitch-2.5.1.tar.gz
cp openvswitch-2.5.1.tar.gz ~/rpmbuild/SOURCES/
tar xfz openvswitch-2.5.1.tar.gz
sed 's/openvswitch-kmod, //g' openvswitch-2.5.1/rhel/openvswitch.spec > openvswitch-2.5.1/rhel/openvswitch_no_kmod.spec
rpmbuild -bb --nocheck ~/openvswitch-2.5.1/rhel/openvswitch_no_kmod.spec
ls -l ~/rpmbuild/RPMS/x86_64/
yum localinstall ~/rpmbuild/RPMS/x86_64/openvswitch-2.5.1-1.x86_64.rpm
systemctl start openvswitch.service
chkconfig openvswitch on

# Now that the installation is completed lets add br-int
ovs-vsctl add-br br-int
Please note that this might not work and will require some fixups.
Fixing the above thing, it is important to setup two bridges - one external, another internal and have to patch them using a patch port
ovs-vsctl add-port  
ovs-vsctl set interface  type=patch
ovs-vsctl set interface  options:peer=
Create an external bridge
# Create interl and external bridges 
ovs-vsctl add-br br-enp0s8
ovs-vsctl add-br br-int

# Create new ports on both the bridges for patching 
ovs-vsctl add-port br-enp0s8 int-patch 
ovs-vsctl add-port br-int enp0s8-patch

# Mark the newly created interfaces as patch interfaces
ovs-vsctl set interface int-patch type=patch
ovs-vsctl set interface enp0s8-patch type=patch

# Connect the patch interfaces 
ovs-vsctl set interface int-patch options:peer=enp0s8-patch
ovs-vsctl set interface enp0s8-patch options:peer=int-patch 

# I am sure there is a better way to do this. Find it out. 
# Now try attaching a docker container/VM to br-int and check if it can be reached from the outside world or not. 
# If it can be reached then your setup was successful.

Configure network and bridges properly. Take help of the article below
# This is the most important part of your network configuration. Here, you must
# select your network mappings. Please, ensure you understand OpenStack
# network philosophy before you configure this.
# Our defaults assumes a flat network configuration with external routers connected
# to an openvswitch br-enp0s9 switch. Change those defaults to suit your network or
# your system will not have a viable network service.
integration_bridge="br-int"
# The bridge_mappings must be set in the form:
# physical_network_name01:bridge_interface01,physical_network_name02:bridge_interface02
# Sample:
# bridge_mappings="physical01:br-eth1,physical02:br-enp0s9,physical03:br-em2"
# VERY IMPORTANT NOTE: Ensure your OVS Bridges are created before you install openstack,
# including br-int and all bridges defined in the "bridge_mappings" variable. Fail
# to do this, and Neutron will be unable to function properlly.
bridge_mappings="physical01:br-enp0s9"
Enable rhel repositories
sudo yum install epel-release
# Verify using 
yum repolist
Fix the python keyring error
wget ftp://mirror.switch.ch/pool/4/mirror/centos/7.3.1611/cloud/x86_64/openstack-mitaka/common/python-keyring-5.7.1-1.el7.noarch.rpm
sudo rpm -i --replacefiles python-keyring-5.7.1-1.el7.noarch.rpm 
sudo yum install -y python-keyring

# For some reason the solution listed above was having issues 
yum remove python-keyring
yum install python-keyring 
# This did the job I don't know why or how. 
Install python-zmq
yum erase -f zeromq
yum versionlock clear
yum install python-zmq
Enable openstack repositores
yum install centos-release-openstack-ocata
Now disable heat installation by going into main-config file.
sudo useradd gnocchi
git clone https://vik_y@bitbucket.org/vik_y/openstack-ocata-installer.git
./main-installer.sh install 

Test this and update
Everything worked well and installation went through fine.
Now go and create a new network from admin section. Assign a new subnet to the network.
Now create the new VM. Make sure you tick the create new volume option as "No".

    This instruction set is mostly to get started with the installation on server by
following the documentation properly.
To test on virtualbox : Create a Virtual Machine with 8GB RAM.
25 GB disk - for os installation
25 GB disk to use as a cinder volume.
Install your centos 7 server with 64 bits and select the packages for a basic infrastructure server. You can pick the graphics environment too but it is not mandatory.
# Install Centos Ocata Repos 
yum -y install centos-release-openstack-ocata
# Install RHEL Repos 
yum -y install https://rdoproject.org/repos/rdo-release.rpm
# Install EPEL Repos
yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm


WARNING: This is VERY important!. Make sure you have the following items configured in
/etc/sysctl.conf:
net.ipv4.ip_forward=1
net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0

yum -y install openvswitch

service openvswitch start

chkconfig openvswitch on
yum -y upgrade
reboot

Then, create the bridges:
First step: br-int (OpenStack integration switch/bridge):
ovs-vsctl add-br br-int
// Change depending on the interface 
Next step: br-enp0s9 (OpenStack networks switch/bridge). Example for "enp0s9" interface:

ovs-vsctl add-br br-enp0s9
ovs-vsctl add-port br-enp0s9 enp0s9
// The above command might break the internet on your server 

Fix it by :
sudo ifconfig enp0s9 
sudo ifconfig enp0s9 0 
sudo ifconfig br-enp0s9 192.168.0.131 netmask 255.255.255.0
sudo route add default gw 192.168.0.1 br-enp0s9

// Now your internet will start working and your openstack network requirement is 
also setup properly. Let's start working with the VMs now and see how we can proceed further 

// One additional step might be required for external connectivity 
// Patching the br-int and br-enp0s9

### Please note patching is not required
### Openstack will do the patching automatically 
### The patching part below is just here for reference. 
# Create new ports on both the bridges for patching 
ovs-vsctl add-port br-enp0s9 int-patch 
ovs-vsctl add-port br-int enp0s9-patch

# Mark the newly created interfaces as patch interfaces
ovs-vsctl set interface int-patch type=patch
ovs-vsctl set interface enp0s9-patch type=patch

# Connect the patch interfaces 
ovs-vsctl set interface int-patch options:peer=enp0s9-patch
ovs-vsctl set interface enp0s9-patch options:peer=int-patch
### Patch part reference ends here

# Check where the 2nd disk is mounted on. 
# Generally the primary disk will be mounted on /dev/sda
# In my case the secondary disk was /dev/sdb
# So I ran the following commands to create my block storage volume.
pvcreate /dev/sdb
vgcreate cinder-volumes /dev/sdb
# NOTE: This would delete anything stored in the /dev/sdb disk
