Tricircle/play with virtualbox

Preparation
One server with Linux kernel (demo is Ubuntu 14.04 LTS)

Install virtualbox
Follow the steps in https://www.virtualbox.org/wiki/Linux_Downloads

First, add the following line to your environment→/etc/apt/sources.list:

deb http://download.virtualbox.org/virtualbox/debian trusty contrib

According to your distribution, replace ‘vivid’ by ‘utopic’, ‘trusty’, ‘raring’, ‘quantal’, ‘precise’, ‘lucid’, ‘jessie’, ‘wheezy’, or ‘squeeze’.

Then, add the Oracle public key for apt-secure:

#wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -

Next, install with apt-get method:

#sudo apt-get update

#sudo apt-get upgrade

#sudo apt-get install virtualbox-5.0

Connect to the virtualbox with x11
First, copy your public key to the ~/authorized_keys.

Then, connect with -X command:

#ssh -X root@HostIP

Next, input the virtualbox to start install virtual machine:

#virtualbox

Then you can see the virtualbox graph interface:

Install Virtual Machines
'''For playing Tricircle, we need to install 3 nodes for devstack. One for the Top OpenStack, two for the cross pod bottom OpenStacks.'''

Configuration of VMs
The most important is to set up networks for use

In order to make the VMs with multiple VLAN networks, then add two network devices for bridge use.

eth0

The eth0 is the default network with NAT methods.

eth2

The same setting as the above, the Promiscuous Mode must be set to “Allow All”. And be in use after reboot.

Installation the VMs
Download an ios for installation

There are many mirror sites in the world. I download a ubuntu-14.04-LTS in the http://mirrors.aliyun.com/ (Alibaba Open Source Mirror Site). Because it’s very fast in China.

Install the Operating System

Follow the steps while installing, because it’s easy, so it will be ignored. After installation, you will see the console like this:

Running in the backgroud
After installation of the VMs, we can login from SSH. So we need to let’s these VMs running in the background. And so when we close the VMs, we need to choose the option:

Playing tricircle with devstack
The detailed methods can be seen in the https://github.com/openstack/tricircle

Configure the Network
Install the openvswitch for creating bridges

#apt-get install openvswitch-switch

Create the stack user
#adduser stack

Give the stack user sudo privileges: 

#sudo apt-get install -y

#su root

#echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

#exit

Download the devstack
#su stack

#sudo apt-get install git -y

#git clone https://git.openstack.org/openstack-dev/devstack

'''Configure the local.conf Change the local.conf to fit your environment. The example is in the Tricircle Project. such as https://github.com/openstack/tricircle/blob/master/devstack/local.conf.sample'''

Install the devstack with Tricircle project
#./stack.sh

After installing the devstack with tricircle, the next step is verifying the installation.

Verifying the installation
Before verifying, it should create the client environment variables to import, such as the script admin-openrc.sh :

export OS_PROJECT_DOMAIN_ID=default

export OS_USER_DOMAIN_ID=default

export OS_PROJECT_NAME=admin

export OS_TENANT_NAME=admin

export OS_USERNAME=admin

export OS_PASSWORD=password#change password as you set in your own environment

export OS_AUTH_URL=http://127.0.0.1:5000

export OS_IDENTITY_API_VERSION=3

export OS_REGION_NAME=RegionOne#It's very important to set region name to the top openstack, because tricircle has different API urls.

'''Modify the verify install scripts as your own environment. And run: '''

#cd tricircle/devstack

#chmod +x verify_top_install.sh

#./verify_top_install.sh 2>&1 | tee logs

It will save the outputs in the logs, you can check if it’s installed correct.

Installing
'''First, in the node1 install the tricircle, and then in the node2 install the tricircle. As the above: '''


 * 1) Modify the networks;
 * 2) Create the stack user;
 * 3) Install git;
 * 4) Download the devstack;
 * 5) Modify the local.conf;
 * 6) Install the devstack with tricircle;

Verifying the tricircle
'''Before verifying, It should create the client environment variables to import, such as the script admin-openrc.sh. ' export OS_PROJECT_DOMAIN_ID=default''

export OS_USER_DOMAIN_ID=default

export OS_PROJECT_NAME=admin

export OS_TENANT_NAME=admin

export OS_USERNAME=admin

export OS_PASSWORD=password#change password as you set in your own environment

export OS_AUTH_URL=http://127.0.0.1:5000

export OS_IDENTITY_API_VERSION=3

export OS_REGION_NAME=RegionOne#It's very important to set region name to the top openstack, because tricircle has different API urls.

'''Modify the verify install scripts as your own environment. And run: '''

#cd tricircle/devstack

#chmod +x verify_top_install.sh

#./verify_top_install.sh 2>&1 | tee logs

One copy logs like: this

Ping test
'''Using the VNC to login the instances in Node1 and Node2. And Ping with each other.'''

VM1 IP : 10.0.1.3/24

#ping -c 4 10.0.2.3

So the cross pod networking has been verified.
