Overview

The purpose of this Topic is to provide details of the Test Plan for testing OpenStack deployments during the Oneiric Ocelot release cycle.

Assumptions

• All topologies will be tested using the ensemble formulas for OpenStack.

• Ensemble services will be unit/relation tested using the formula-tester formula
• Deploy topologies will be tested functionally using XXXX

Topologies

Single Node

Overview

The purpose of this topology is to allow easy enablement for OpenStack development and is not intended for use in production deployments.

A single node deployment consists of the following components:

• Nova (api, scheduler, compute, network)
• Hypervisor support: KVM and LXC (compute-kvm, compute-lxc)
• glance
• rabbitmq-server
• API Server

nova-network will be configured to use the default VLANManager.

In-scope

• Tests that will be validated against this topology

Out-of-scope

• Support for Xen hypervisor
• Use of MySQL database
• Deployment of swift
• Deployment of keystone

OpenStack-SingleNode-KVM

Basic Oneiric Server Installation

Perform a standard Oneiric Server amd64 installation; recommendation is that openssh-server is installed to make configuring the node easier.

Test Procedure

1. Install bridge-utils:

sudo apt-get install bridge-utils

1. Edit /etc/network/interfaces (IP addresses will need to be changed depending on the network configuration of the testing environment):

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
#auto eth0
#iface eth0 inet dhcp
# This is an autoconfigured IPv6 interface
#iface eth0 inet6 auto

auto br0
iface br0 inet static
        address 192.168.0.10
        network 192.168.0.0
        netmask 255.255.255.0
        broadcast 192.168.0.255
        gateway 192.168.0.1
        bridge_ports eth0
        bridge_fd 9
        bridge_hello 2
        bridge_maxage 12
        bridge_stp off

1. Reboot

TEST: Validate that br0 is running

ip addr
<VOID 1> capture output

1. Install OpenStack packages

sudo apt-get install nova-compute nova-compute-kvm nova-scheduler nova-objectstore nova-network nova-api glance rabbitmq-server unzip

TEST: Validate that relevant nova processes are running

prompt> pgrep -u nova -l | sort -k 2
1128 nova-api
1123 nova-compute
1112 nova-network
1122 nova-objectstor
1129 nova-scheduler
1109 su
1119 su
1121 su
1125 su
1127 su

TEST: Validate that relevant rabbitmq processes are running

prompt> pgrep -u rabbitmq -l | sort -k 2
1443 beam.smp
1592 cpu_sup
1423 epmd
1594 inet_gethost
1595 inet_gethost
1441 sh
1438 su

TEST: Validate that relevant glance processes are running

prompt>  pgrep -u glance -l | sort -k 2
1089 glance-api
1086 glance-registry
1084 su
1088 su

1. Setup nova components

sudo nova-manage db sync
sudo nova-manage user admin admin
sudo nova-manage project create test-cloud-01 admin
sudo nova-manage network create private 10.0.0.0/8 3 16 --bridge_interface=br0
sudo nova-manage floating create 192.168.0.220/27

The final command should be adjusted to create an appropriate network range within the test network configuration for access of public IP addresses.

This might be helpful - http://www.subnet-calculator.com/subnet.php?net_class=C.

TEST: Validate that appropriate private network ranges have been created

prompt> sudo nova-manage network list
id      IPv4                    IPv6            start address   DNS1            DNS2            VlanID          project         uuid           
1       10.0.0.0/28             None            10.0.0.3        None            None            100             None            None           
2       10.0.0.16/28            None            10.0.0.19       None            None            101             None            None           
3       10.0.0.32/28            None            10.0.0.35       None            None            102             None            None      

TEST: Validate that floating 'public' network addresses have been allocated

prompt> sudo nova-manage floating list
None    192.168.0.192   None
None    192.168.0.193   None
None    192.168.0.194   None
None    192.168.0.195   None
None    192.168.0.196   None
...
None    192.168.0.223   None

1. Download project access credentials and unzip

sudo nova-manage project zipfile test-cloud-01 admin
unzip nova.zip
. novarc

TEST: Zip file named 'nova.zip' created in current working directory containing

prompt> unzip -l nova.zip
Archive:  nova.zip
  Length      Date    Time    Name
---------  ---------- -----   ----
     1184  2011-09-06 08:55   novarc
      887  2011-09-06 08:55   pk.pem
     2520  2011-09-06 08:55   cert.pem

     5620                     4 files

Length, Date and Time will vary from the above

1. Install cloud-utils, download a cloud image and upload to OpenStack

First:

sudo apt-get install cloud-utils

Then download the relevant test image from cloud-images.ubuntu.com and publish to OpenStack:

ARCH=amd64
CLOUD_TGZ=ubuntu-11.10-beta1-server-cloudimg-$ARCH.tar.gz
URL=http://cloud-images.ubuntu.com/releases/oneiric/beta-1/
TYPE=m1.tiny
BUCKET="cloudtest-$(date +%Y%m%d%H%M%S)"
[ $ARCH = "amd64" ] && IARCH=x86_64 || IARCH=i386
[ ! -e $CLOUD_TGZ ] && wget $URL/$CLOUD_TGZ
EMI=$(cloud-publish-tarball $CLOUD_TGZ $BUCKET $IARCH | awk -F \" '{print $2}') && echo $EMI

TEST: Validate that cloud image is ready for use

prompt> euca-describe-images
<VOID 2>

Then create a keypair (if required), and run an instance, allocating and associating a 'public' ip address:

if [ ! -e mykey.priv ]; then
    touch mykey.priv
    chmod 0600 mykey.priv
    euca-add-keypair mykey > mykey.priv
fi
euca-authorize default -P tcp -p 22 -s 0.0.0.0/0
euca-authorize default -P icmp -t -1:-1 -s 0.0.0.0/0
INSTANCEID=$(euca-run-instances -k mykey $EMI -t $TYPE | awk '/^INSTANCE/ {print $2}') && echo $INSTANCEID
PUBLICIP=$(euca-allocate-address | awk '{print $2}')
euca-associate-address -i $INSTANCEID $PUBLICIP

TEST: Check that instance is accessible via SSH locally

IPADDR=$(euca-describe-instances | grep $INSTANCEID | grep running | awk '{print $4}')
ssh -i mykey.priv ubuntu@$IPADDR

TEST: Check that instance is accessible via SSH remotely

scp test-host:* .
. novarc
ssh -i mykey.priv ubuntu@$IPADDR
