===== Fedora: Using udev rename, networkManager =====
Fix
    systemctl restart NetworkManager.service


===== Fedora: Fix udev, NetworkManager =====
Disable systemd-udevd remane network iface

Approach 1:
     vi /boot/grub/grub.conf
     Pass biosdevname=0 to kernel command line

Approach 2: You may continue to write rules in /etc/udev/rules.d/70-persistent-net.rules to change the device names to anything you wish. Such will take precedence over this physical location naming scheme. Such rules may look like:

     SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:11:22:33:44:55", ATTR{type}=="1", KERNEL=="eth*", NAME="public"

Disable NetworkManager and enable network

    systemctl stop NetworkManager.service
    systemctl disable NetworkManager.service
    rm /etc/sysconfig/network-scripts/ifcfg-enp5s0f1
    
    systemctl start network.service
    systemctl enable network.service

===== Fedora: firewalld =====

Disable firewalld
    systemctl stop firewalld
    systemctl disable firewalld
    yum install iptables-services
    # Create this below file, otherwise starting iptables will fail
    touch /etc/sysconfig/iptables
    systemctl enable iptables && systemctl start iptables
    
    
    
====== Prepare Installation on each VM ======
===== Host: =====

    vim /etc/hosts
    
    192.168.200.209	controller
    192.168.200.212	compute
    192.168.200.215	network

===== Fedora Network: =====
There are 3 networks
<code>
# The primary network interface - VirtualBox NAT connection
# (VirtualBox Network Adapter 1)
auto eth0
iface eth0 inet dhcp

# VirtualBox vboxnet0 - OpenStack management network
# (VirtualBox Network Adapter 2)
auto eth1
iface eth1 inet static
address 10.10.10.51
netmask 255.255.255.0

# VirtualBox vboxnet2 - OpenStack API network
# (VirtualBox Network Adapter 3)
auto eth2
iface eth2 inet static
address 192.168.100.51
netmask 255.255.255.0
</code>


    ip a
    # see a list of network

===== Maven: =====

    yum install maven -y
    # java etc also installed
    
    sudo cd /opt
    wget http://apache.openmirror.de/maven/maven-3/3.2.3/binaries/apache-maven-3.2.3-bin.tar.gz
    tar -xvzf apache-maven
    
    
===== JAVA_HOME =====

    vim .bash_profile
<code>    
# User specific environment and startup programs
export M2_HOME=/opt/apache-maven-3.2.3
export M2=$M2_HOME/bin
export MAVEN_OPTS='-Xms256m -XX:MaxPermSize=1024m -Xmx1024m'

export JVM_ROOT=/usr/lib/jvm
export JAVA_HOME=$JVM_ROOT/java

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH=$JAVA_HOME:$M2:$PATH
</code>
    source .bash_profile

On other nodes
    sudo scp -rp root@controller:/opt/apache-maven* /opt/
    scp -rp fedora@controller:~/.bash_profile ./.bash_profile
    source .bash_profile
    
===== Misc =====

    sudo yum install python-pip.noarch
    pip install git-review
