VNX Openstack Antelope four nodes classic scenario using Open vSwitch

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 node, a network node and two compute nodes, all based on LXC. Optionally, new compute nodes can be added by starting additional VNX scenarios.

Openstack version used is Antelope (2023.1) over Ubuntu 22.04 LTS. The deployment scenario is the one that was named "Classic with Open vSwitch" and was described in previous versions of Openstack documentation (https://docs.openstack.org/liberty/networking-guide/scenario-classic-ovs.html). It is prepared to experiment either with the deployment of virtual machines using "Self Service Networks" provided by Openstack, or with the use of external "Provider networks".

The configuration has been developed integrating into the VNX scenario all the installation and configuration commands described in Openstack Antelope installation recipes.

Figure 1: Openstack tutorial scenario

Requirements

To use the scenario you need a Linux computer (Ubuntu 20.04 or later recommended) with VNX software installed. At least 12GB 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

Installation

Download the scenario with the virtual machines images included and unpack it:

wget http://idefix.dit.upm.es/vnx/examples/openstack/openstack_lab-antelope_4n_classic_ovs-v01-with-rootfs.tgz
sudo vnx --unpack openstack_lab-antelope_4n_classic_ovs-v01-with-rootfs.tgz

Starting the scenario

Start the scenario and configure it and load an example cirros and ubuntu images with:

cd openstack_lab-antelope_4n_classic_ovs-v01
# Start the scenario
sudo vnx -f openstack_lab.xml -v --create
# Wait for all consoles to have started and configure all Openstack services
vnx -f openstack_lab.xml -v -x start-all
# Load vm images in GLANCE
vnx -f openstack_lab.xml -v -x load-img

Figure 2: Openstack tutorial detailed topology

Once started, you can connect to Openstack Dashboard (default/admin/xxxx) starting a browser and pointing it to the controller horizon page. For example:

firefox 10.0.10.11/horizon

Self Service networks example

Access the network topology Dashboard page (Project->Network->Network topology) and create a simple demo scenario inside Openstack:

vnx -f openstack_lab.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).

You can create a second Cirros virtual machine (vm2) or a third Ubuntu virtual machine (vm3) and test connectivity among all virtual machines with:

vnx -f openstack_lab.xml -v -x create-demo-vm2
vnx -f openstack_lab.xml -v -x create-demo-vm3

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

Besides, you can access the Openstack controller by ssh from the host and execute management commands directly:

slogin root@controller     # root/xxxx
source bin/admin-openrc.sh # Load admin credentials

For example, to show the virtual machines started:

openstack server list

You can also execute that commands from the host where the virtual scenario is started. For that purpose you need to install openstack client first:

pip install python-openstackclient
source bin/admin-openrc.sh # Load admin credentials
openstack server list

Provider networks example

Compute nodes in the Openstack virtual lab scenario have two network interfaces for internal and external connections:

• eth2, connected to Tunnels network and used to connect with VMs in other compute nodes or routers in the network node
• eth3, connected to VLANs network and used to connect with VMs in other compute nodes and also to connect to external systems through the Providers networks infrastructure.

To demonstrate how Openstack VMs can be connected with external systems though the VLAN network switches, an additional demo scenario is included. Just execute:

vnx -f openstack_lab.xml -v -x create-vlan-demo-scenario

That scenario will create two new networks and subnetworks associated with VLANs 1000 and 1001, and two VMs, vmA1 and vmB1 connected to that networks. You can see the scenario created through the openstack Dashboard.

Figure 3: Provider networks testing scenario

The commands used to create that networks and vms are the following (can be consulted also in the scenario XML file):

# Networks
openstack network create --share --provider-physical-network vlan --provider-network-type vlan --provider-segment 1000 vlan1000
openstack network create --share --provider-physical-network vlan --provider-network-type vlan --provider-segment 1001 vlan1001
openstack subnet create --network vlan1000 --gateway 10.1.2.1 --dns-nameserver 8.8.8.8 --subnet-range 10.1.2.0/24 --allocation-pool start=10.1.2.2,end=10.1.2.99 subvlan1000
openstack subnet create --network vlan1001 --gateway 10.1.3.1 --dns-nameserver 8.8.8.8 --subnet-range 10.1.3.0/24 --allocation-pool start=10.1.3.2,end=10.1.3.99 subvlan1001

# VMs
mkdir -p tmp
openstack keypair create vmA1 > tmp/vmA1
openstack server create --flavor m1.tiny --image cirros-0.3.4-x86_64-vnx vmA1 --nic net-id=vlan1000 --key-name vmA1
openstack keypair create vmB1 > tmp/vmB1
openstack server create --flavor m1.tiny --image cirros-0.3.4-x86_64-vnx vmB1 --nic net-id=vlan1001 --key-name vmB1

To demonstrate the connectivity of vmA1 and vmB1 to external systems connected on VLANs 1000/1001, you can start and additional virtual scenario which creates three additional systems: vmA2 (vlan 1000), vmB2 (vlan 1001) and vlan-router (connected to both vlans). To start it just execute:

vnx -f openstack_lab-vms-vlan.xml -v -t

Figure 4: Provider networks demo external scenario

Once the scenario is started, you should be able to ping, traceroute and ssh among vmA1, vmB1, vmA2 and vmB2 using the following IP addresses:

• Virtual machines inside Openstack:
• vmA1 and vmB1: dynamic addresses assigned from 10.1.2.0/24. You can consult the addresses from Horizon or using the command:

openstack server list

• Virtual machines outside Openstack:
• vmA2: 10.1.2.100/24
• vmB2: 10.1.3.100/24

Take into account that the pings from the exterior virtual machines to the internal ones is not allowed by the default security groups filters applied by Openstack.

You can have a look at the virtual switch that supports the Openstack VLAN Network executing the following command in the host:

ovs-vsctl show

Figure 5: Openstack Dashboard view of the demo virtual scenarios created

Adding additional compute nodes

Three additional VNX scenarios are provided to add new compute nodes to the scenario.

For example, to start compute nodes 3 and 4, just:

vnx -f openstack_lab-cmp34.xml -v -t
# Wait for consoles to start
vnx -f openstack_lab-cmp34.xml -v -x start-all

After that, you can see the new compute nodes added by going to "Admin->Compute->Hypervisors->Compute host" option. However, the new compute nodes are not added yet to the list of Hypervisors in "Admin->Compute->Hypervisors->Hypervisor" option.

To add them, just execute:

vnx -f openstack_lab.xml -v -x discover-hosts

The same procedure can be used to start nodes 5 and 6 (openstack_lab-cmp56.xml) and nodes 7 and 8 (openstack_lab-cmp78.xml).

Stopping or releasing the scenario

To stop the scenario preserving the configuration and the changes made:

vnx -f openstack_lab.xml -v --shutdown

To start it again use:

vnx -f openstack_lab.xml -v --start

To stop the scenario destroying all the configuration and changes made:

vnx -f openstack_lab.xml -v --destroy

To unconfigure the NAT, just execute (change eth0 by the name of your external interface):

vnx_config_nat -d ExtNet eth0
