Prepare VMs
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
# 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

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
# 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
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
Troubleshooting
- VM send bootp but has no IP
- Check dnsmasq on host machine
- Restart NetworkManager
