2. 2 This Week  Building Clouds –Eucalyptus –OpenNebula –ESXi APIs  Virtualization –Xen and Art of Virtualization

3. 3 Open Nebula and Open Nebula Express  http://www.opennebula.org/documentation:documentation http://www.opennebula.org/documentation:documentation  http://www.opennebula.org/software:ecosystem:opennebula_express http://www.opennebula.org/software:ecosystem:opennebula_express  Provides interfaces to create services on top of VMs and manage, monitor and control  You need to install OpenNebula on one machine and have one or more machines with a hypervisor (xen, KVM, ESX) as managed nodes  Three different interfaces –Command line (CLI) –XML-RPC API –Libvirt  Process of creating a VM using CLI –1. Create an image that you want the VM to host (i.e., fedora with LAMP stack) –2. Create a template that describes the resources VM will use ( 1 cpu, 1GB mem, etc) –3. Use CLI to instantiate the VM with the image that you need

4. 4 Examples of some functionalities  Some functionalities –List managed hosts: here there are two nodes host01, host02 –Example template for creating a VM –Create a VM with the template and image –List the created VMs Application image that you want to instantiate

5. 5 What I want you to try  Install Open Nebula Express  Install few managed nodes with KVM and/or Xen  Use Open Nebula to create a VM with image  We could provide a sample image and template for you to use
