1 OpenNebula Cloud Management Platform > Innovative Open Source Technologies and Professional Services to Build your Enterprise-ready Cloud Computing Environment Installing and Basic Usage Carlos Martín OpenNebula Project Engineer EGI Community Forum Helsinki, May 2014 Acknowledgments The research leading to these results has received funding from the European Union's Seventh Framework Programme ([FP7/ ]) under grant agreement n (CloudCatalyst Project) Creative Commons Attribution-NonCommercial-ShareAlike License

2 2 Agenda Installing and Basic Usage Planning the Installation Installation (node 1 - Frontend) Installation (node 2 - WorkerNode) Configuration Basic Usage Managing Hosts Images, Networks, Templates and VMs Managing Users, Quotas and ACLs Logging & Debugging

3 3 OpenNebula Views Different perspectives for different users Admin VDCAdmin OpenNebula Cloud User

4 4 OpenNebula Views Configure your Cloud from the Admin perspective Admin VDCAdmin OpenNebula Cloud User

5 5 A Typical OpenNebula Environment Planning the Installation Monitoring,Virtualization, Storage and Network Repository of VM images Multiple Backends (LVM, Ceph) Provides physical resources for the VMs Must have a hypervisor installed

6 6 Virtual Lab Planning the Installation NODE 1 NODE 2

7 7 Virtual Lab Installing Start node1. node2 must be started after node1 You can access them from: 1. VirtualBox GUI 2. Console/putty node1 (password centos) $ ssh localhost -l root -p 2222 node2 (password centos) $ ssh localhost -l root -p 2223

8 8 Installation node 1 - Frontend Installing Hands on (node1)! Install Packages # yum install opennebula-server opennebula-sunstone opennebula-node-kvm opennebula-flow opennebula-gate Configure the OpenNebula Services # sed -i 's/"kvm" ]/"qemu" ]/' /etc/one/oned.conf # echo 'ONEGATE_ENDPOINT = " >> /etc/one/oned.conf # sed -i 's/ / /' /etc/one/sunstone-server.conf # sed -i '/^:market/d' /etc/one/sunstone-server.conf # echo ':marketplace_url: >> \ /etc/one/sunstone-server.conf # sed -i 's/ / /' /etc/one/onegate-server.conf

9 9 Installation node 1 - Frontend Installing Hands on (node1)! Start the services # chmod 755 /etc/one # gpasswd -a oneadmin wheel # service opennebula start # service opennebula-sunstone start # service libvirtd restart # su - oneadmin Overview of the CLI $ oneuser show $ oneuser -h

10 10 Installation node 1 - Frontend Installing Hands on (node1)! OpenNebula CLI Commands $ one[tab] oneuser Manage Users oneimage Manage Images onegroup Manage Groups onetemplate Manage Templates oneacl Manage ACLs onevm Manage VMs onehost Manage Hosts oneacct Accounting Tool onecluster Manage Clusters onemarket Marketplace Tool onevnet Manage Networks onedb DB Tool onedatastore Manage Datastores

11 11 Installation node 2 Worker Node Installing Hands on (node2)! Install Packages # yum install opennebula-node-kvm Start the services # service libvirtd restart

12 12 Configure Password-less SSH Installing Hands on! (always node1 from now on) OpenNebula needs passwordless ssh access to all the nodes from all the nodes: # (as oneadmin) $ ssh-keyscan node1 node2 > ~/.ssh/known_hosts # test it! $ ssh node2 $ exit $ ssh node1 $ exit

13 13 Get User Information - Sunstone Installing Get the Sunstone Login information # (as oneadmin) $ cat ~/.one/one_auth oneadmin:<password> Try out sunstone!

14 Adding Hosts - Sunstone Installing and Basic Usage 14 Basic Usage Hosts Hands on! (Sunstone) Create one host in Sunstone: node1 Virtualization: KVM Information: KVM Network: dummy Cluster: none Watch transition INIT => ON Click on the row for more information Automatic gathering of monitoring data Take a look at the graphs

15 Adding Hosts - CLI Installing and Basic Usage 15 Basic Usage Hosts Hands on! (CLI) (always as oneadmin in the Frontend node 1) $ onehost -help $ onehost create -help $ ssh node2 ls -ld /var/tmp/one $ onehost create node2 -i kvm -v kvm -n dummy $ onehost list $ onehost top # Wait for ON... and then CTRL-C $ ssh node2 ls ld /var/tmp/one $ onehost show node2 $ onehost show 1 $ onehost show -x 1

16 Adding Images Basic Usage Images Hands on! (Sunstone) Create a new Image Name: ttylinux Path: /var/www/html/ttyvd-context.qcow2 Set Attributes: DEV_PREFIX=vd DRIVER=qcow2 Installing and Basic Usage 16

17 Datastores Installing and Basic Usage 17 Overview Hands on! (Sunstone)

18 Adding Networks Basic Usage Networks Hands on! (Sunstone) Click Create Name: private IP: => [ENTER] => Network Model: default Bridge: br1 VM VM VM VM br1 br1 eth1 Node 1 eth1 Node 2 Installing and Basic Usage 18

19 Adding Templates Basic Usage Template Hands on! (Sunstone) A template is a Virtual Machine definition ready to be instantiated It has CPU, Memory, Disks, NIC, Graphical Ports, etc... Installing and Basic Usage General Name: ttylinux CPU: 0.1 Memory: 64M Storage Click ttylinux Network Click private Model virtio OS Booting Arch x86_64 Input/Output Click VNC and add Keymap 19

20 Instantiating Installing and Basic Usage 20 Basic Usage VMs Hands on! (Sunstone) Instantiate the template Deploy 2 VMs Leave the name blank Open Virtual Machines Watch the transition PENDING => RUNNING Deployed in different hosts VNC ( root / password ) ifconfig: configured using context ping the other machine migrate live-migrate

21 Main VM actions Installing and Basic Usage 21 Contextualization Hands on! Login to the first VM and look at contextualization Take a look at the contextualization files:

22 22 Main VM actions Basic Usage VMs suspend power off (--hard) stop undeploy (--hard) reboot (--hard) delete --recreate shutdown (--hard) delete VM state saved. Kept in the host. Powers off a VM. Kept in the host. VM state saved. Taken to the system datastore. Powers off a VM. Taken to the system datastore. Reboots the VM. Cleans the VM and moves it to PENDING. Powers off a VM, cleans host and VM is removed from OpenNebula. VM is immediately destroyed regardless of state. Recommended only for oneadmin.

23 Other VM actions Installing and Basic Usage 23 Basic Usage VMs Hands on! (Sunstone) Storage: Attach new disk Create new Image => Type: Datablock ; Empty Datablock ; Size: 100; FS Type: qcow2 ; Device Prefix: vd ; Driver: qcow2 Network: Attach new nic (model virtio) Snapshot echo 1 >> /sys/bus/pci/rescan fdisk -l Take snapshot Modify the VM Revert Capacity: Do a poweroff --hard. Then resize VM capacity

24 Permissions Installing and Basic Usage 24 Chmod and Chown, UNIX Style! Hands on! (Sunstone) Make the all the resources previously created usable by everybody Apply to all the images, templates and virtual networks. Owner could be changed too => chown and chmod.

25 Groups Installing and Basic Usage 25 Creating Groups Hands on! Resources: adds the whole OpenNebula Zone Admin: Create an Administrator User Permissions: Keep defaults

26 26 Groups Associated ACLs Hands on! When a group is created, a new set of ACLs are introduced

27 27 OpenNebula Views Configure your Cloud from the Admin perspective Admin VDCAdmin OpenNebula Cloud User

28 28 Groups Using Groups Hands on! Login as students-admin and change the view to vdcadmin Create a new student and update the Quotas

29 29 OpenNebula Views Configure your Cloud from the Admin perspective Admin VDCAdmin OpenNebula Cloud User

30 Users Cloud View Hands on! Login as the student and instantiate a new VM Select the ttylinux template Customize => Small x1 Network private Explore the VM actions. Power Off and Save VM Other options: SSH Key, Quotas, Settings With the oneadmin account see the new template and image Installing and Basic Usage 30

31 Other Interesting Features Installing and Basic Usage 31 Federation OpenNebula can scale by federation many OpenNebula instances. Scheduler The OpenNebula Scheduler is extremely flexible. Write your own rules you want to guarantee that your vms end up wherever you need them. OneFlow Manage multi-vm services OneGate Send custom Metrics to OpenNebula AppMarket Deliver appliances ready to be consumed CloudBursting Scale out your private resources to EC2
