Introduction
This is an Openstack tutorial scenario designed to experiment with Openstack free and open-source software platform for cloud-computing.
The scenario is made of four virtual machines: a controller based on LXC and a network node and two compute nodes based on KVM. Optionally, a third compute node can be added once the scenario is started.
All virtual machines use Ubuntu 14.04.3 LTS and Openstack Kilo.
The scenario has been inspired by the ones developed by Raul Alvarez to test OpenDaylight-Openstack integration, but instead of using Devstack to configure Openstack nodes, the configuration is done by means of commands integrated into the VNX scenario following Openstack installation recipes in http://docs.openstack.org/kilo/install-guide/install/apt/content/
Requirements
To use the scenario you need a Linux computer (Ubuntu 14.04 or later recommended) with VNX software installed. At least 4Gb of memory are needed to execute the scenario.
See how to install VNX here: http://vnx.dit.upm.es/vnx/index.php/Vnx-install
If already installed, update VNX to the latest version with:
vnx_update
To make startup faster, enable one-pass-autoconfiguration for KVM virtual machines in /etc/vnx.conf:
[libvirt] ... one_pass_autoconf=yes
Check that KVM nested virtualization is enabled:
cat /sys/module/kvm_intel/parameters/nested Y
If not enabled, check, for example, http://docs.openstack.org/developer/devstack/guides/devstack-with-nested-kvm.html to enable it.
Installation
Download the scenario with the virtual machines images included and unpack it:
wget http://idefix.dit.upm.es/vnx/examples/openstack/openstack_tutorial-kilo_4nodes_basic-v014-with-rootfs.tgz vnx --unpack openstack_tutorial-kilo_4nodes_basic-v014-with-rootfs.tgz
Alternatively, you can download the much lighter version without the images and create the root filesystems from scratch in your computer:
wget http://idefix.dit.upm.es/vnx/examples/openstack/openstack_tutorial-kilo_4nodes_basic-v014.tgz vnx --unpack openstack_tutorial-kilo_4nodes_basic-v014.tgz cd openstack_tutorial-kilo_4nodes_basic-v014/filesystems ./create-lxc_ubuntu64-ostack-controller ./create-kvm_ubuntu64-ostack-compute ./create-kvm_ubuntu64-ostack-network
Starting the scenario
Start the scenario and configure it and load an example cirros image with:
cd openstack_tutorial-kilo_4nodes_basic-v014 vnx -f openstack_tutorial-kilo_4nodes_basic.xml -v -t vnx -f openstack_tutorial-kilo_4nodes_basic.xml -v -x start-all vnx -f openstack_tutorial-kilo_4nodes_basic.xml -v -x load-img
Once started, you can connect to Openstack Dashboard (admin/xxxx) starting a browser and pointing it to the controller horizon page. For example:
firefox 10.0.10.11/horizon
Access Dashboard page "Project|Network|Network topology" and create a simple demo scenario inside Openstack:
vnx -f openstack_tutorial-kilo_4nodes_basic.xml -v -x create-demo-scenario
You should see the simple scenario as it is being created through the Dashboard.
Once created you should be able to access vm1 console, to ping or ssh from the host to the vm1 or the opposite (see the floating IP assigned to vm1 in the Dashboard, probably 10.0.10.102).
Finally, to allow external Internet access from vm1 you hace to configure a NAT in the host. You can easily do it using vnx_config_nat command distributed with VNX. Just find out the name of the public network interface of your host (i.e eth0) and execute:
vnx_config_nat ExtNet eth0
Stopping or releasing the scenario
To stop the scenario preserving the configuration and the changes made:
vnx -f openstack_tutorial-kilo_4nodes_basic.xml -v --shutdown
To start it again use:
vnx -f openstack_tutorial-kilo_4nodes_basic.xml -v --start
To stop the scenario destroying all the configuration and changes made:
vnx -f openstack_tutorial-kilo_4nodes_basic.xml -v --destroy
To unconfigure the NAT, just execute:
vnx_config_nat -d ExtNet eth0
Adding a third compute node (compute3)
To add a third compute node to the scenario once it is started you can use the VNX modify capacity:
vnx -s openstack_tutorial-kilo_4nodes_basic --modify others/add-compute3.xml -v vnx -s openstack_tutorial-kilo_4nodes_basic -v -x start-all -M compute3
Once the new node has been joined to the scenario, you must use "-s" option instead of "-f" to manage it (if not, the compute3 node will not be considered). For example,
vnx -s openstack_tutorial-kilo_4nodes_basic -v --destroy
Other useful information
To pack the scenario in a tgz file including the root filesystems use:
bin/pack-scenario --include-rootfs
To pack the scenario without the root filesystems, just delete the "--include-rootfs" parameter.
