Ubuntu Server 12.04 LTS, Eucalyptus and Xen

In this installation, 2 Dell machines (Dual Core, 4GB RAM, 250 GB hard disk) and 1 IBM x3650 machine are used. 

1. Install Eucalyptus cloud and cluster controller (Dell)

1.1. Ubuntu Server 12.04 LTS 
  • default installation on openssh
  • make network is set correctly
1.2 Install postfix which will be used by Eucalyptus for sending confirmation emails to new registered users.
1.3 Install Eucalyptus
1.3.1 download and add pub key
  • sudo apt-key add c1240596-eucalyptus-release-key.pub
 
1.3.2 add deb
Create a file in /etc/apt/sources.list.d called eucalyptus.list with the following content:
  • deb http://downloads.eucalyptus.com/software/eucalyptus/3.1/ubuntu precise main

 On all machines that will run either Eucalyptus or Euca2ools, create a file in/etc/apt/sources.list.d called euca2ools.list with the following content:
  • deb http://downloads.eucalyptus.com/software/euca2ools/2.1/ubuntu precise main
1.3.3 install
  • sudo apt-get update  
  • sudo apt-get install eucalyptus-cloud eucalyptus-cc eucalyptus-walrus
1.3.4 start
  • /usr/sbin/euca_conf --initialize (for first time)
    sudo service eucalyptus-cloud start
    sudo service eucalyptus-cc start 

    1.3.5 verify
    check on Web browser: https://<ip>:8443
first time login will allow changing password, set email address admin/admin


2. Install Eucalyptus node controller (IBM)

2.1 Repeat 1.1, 1.3.1, 1.3.2
2.2 install Xen
  • sudo apt-get install iproute  iptables module-init-tools python2.5 python2.6
  • sudo apt-get  install xen-utils
2.3 Modify GRUB to boot default on Xen
sudo sed -i 's/GRUB_DEFAULT=.*\+/GRUB_DEFAULT="Xen 4.1-amd64"/' /etc/default/grub
sudo update-grub
 
Set the default toolstack to xm (aka xend):
sudo sed -i 's/TOOLSTACK=.*\+/TOOLSTACK="xm"/' /etc/default/xen
Now reboot:
sudo reboot
And then verify that the installation has succeeded: 
sudo xm list
Name ID Mem VCPUs State Time(s)
Domain-0 0 945 1 r----- 11.3

2.4 Network configuration
check eth0 or eth1 is used. the following assumes eth0 and dhcp are used.

sudo apt-get install bridge-utils
 
Edit /etc/network/interfaces, and add this:  

auto xenbr0
iface xenbr0 inet dhcp
    bridge_ports eth0
 
Restart networking to enable xenbr0 bridge: 
 
sudo service networking restart


 
2.5 install Eucalyptus node controller
  • sudo apt-get install eucalyptus-nc
    sudo service eucalyptus-nc start

3. Register

 Register CC (at CLC machine)

sudo /usr/sbin/euca_conf --register-cluster --partition cluster01  --host  10.1.62.178 --component  cc-10.1.62.178
(this may require root access: using sudo passwd to add a new password for root)

 Register NC (at CC machine)

 
sudo /usr/sbin/euca_conf --register-nodes "<node0_IP_address> ... <nodeN_IP_address>"

Register walrus at CLC machine

sudo /usr/sbin/euca_conf --register-walrus --partition walrus --host <walrus_IP_address> --component <walrus-hostname>

4. Install Eucalyptus client machine (Dell)

4.1 install Ubuntu Desktop 12.04 LTS
4.2 repeat 1.3.1 and 1.3.2
4.3 install euca2ools
  • sudo apt-get install euca2ools
apply a new user account from @8443

Get admin credentials
login as eucalyptus/admin @ 8443

download new credentials from admin@eucalyptus
unzip to ~/.euca
mkdir ~/.euca cd ~/.euca unzip <filepath>/euca2-<user>-x509.zip
source eucarc
<*remember to use admin credential to source*>

4.4 Add image from eustore
eustore-describe-images
eustore-install-image -b testbucket -i xxxxxxxx -k xen
<*this will take a while*>
the results look like as follows:

    Hello,
    I am new on Eucalyptus. I got to put an instance on my Eucalyptus when I was using KVM. But when I switch to xen, my instance doesn't get IP. I also can't run "euca-get-console-output" anymore. Do you have any clue? Thanks for your shareing on this blog!
