  • 10Installing and Basic Usage 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
  • 11Installing and Basic Usage Get User Information - Sunstone Installing ● Get the Sunstone Login information ● Try out sunstone! http://localhost:9869 # (as oneadmin) $ cat ~/.one/one_auth oneadmin:<password>

(Sunstone) ● Create one host in Sunstone: node1 ● Virtualization: KVM ● Information: KVM ● Network: dummy ● Cluster: dummy ● Watch transition INIT  ON ● Click on the row for more information ● Automatic gathering of monitoring data ● Take a look at the graphs
  • 15Installing and Basic Usage Adding Hosts - CLI 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
  • 16Installing and Basic Usage Adding Images Basic Usage – Images Hands on! (Sunstone) ● Create an Image in Sunstone ● Name: tty ● Provide a Path: /var/tmp/tutorial/ttylinux.qcow2.img ● Advanced  Driver: qcow2 ● Datastore: default ● Create! ● Watch transition LOCKED  READY ● Ownership and Permissions (ala Unix!), Size, Driver... Hands on! (CLI) $ oneimage list $ oneimage show tty # DO NOT EXECUTE THE FOLLOWING COMMAND $ oneimage create --name tty --driver qcow2 --path /var/tmp/tutorial/ttylinux.qcow2.img -d default
  • 17Installing and Basic Usage System Datastore Basic Usage – Datastores Hands on! (Sunstone) ● Inspect each Datastore: ● The system datastore: ● Holds images for running VMs ● The TM_MAD (transfer manager driver) is shared which means:
  • 18Installing and Basic Usage Shared Datastore Basic Usage – Datastores Hands on! (Sunstone) ● The default datastore: ● Holds images ready to be cloned or linked for VMs ● The DS_MAD is fs because our image is a regular file ● The TM_MAD (transfer manager driver) is shared which means:
  • 19Installing and Basic Usage Adding Networks Basic Usage – Networks Hands on! (Sunstone) ● Create a new Network ● Name: private ● Type: Fixed Network ● IP: 192.168.0.1 -> [ENTER] -> repeat ... -> 192.168.0.4 ● Network Model: default ● Bridge: br1 br1 VM VM Node 1 eth1 br1 Node 2 eth1 VM VM
  • 20Installing and Basic Usage Adding Networks Basic Usage – Networks Hands on! (Sunstone) ● Network extended information: ● Lease Management  Add, Hold and Remove Leases Hands on! (CLI) $ cat private2.net NAME = private2 TYPE = fixed BRIDGE = br1 LEASES = [ IP = 10.0.0.1 ] LEASES = [ IP = 10.0.0.2 ] $ onevnet create private2 $ onevnet list $ onevnet show private $ onevnet addleases private 192.168.0.105 $ onevnet hold private 192.168.0.105
  • 21Installing and Basic Usage 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... ● Create a new Template: ● Name: ttylinux ● CPU: 0.1 ● Memory: 64M ● Storage: tty ● Network: private ● Input/Output: VNC + Keymap ● Random values in Context  Custom Variables ● Create!
  • 22Installing and Basic Usage Adding Templates Basic Usage – Template Hands on! (CLI) ● Try the useful --dry option in the CLI $ onetemplate create --help $ onetemplate create --name ttylinux --cpu 0.1 --memory 64 --disk tty --nic private --vnc --dry NAME="ttylinux“ CPU=0.1 MEMORY=64 DISK=[ IMAGE="tty“ ] NIC=[ NETWORK="private“ ] GRAPHICS=[ TYPE="vnc", LISTEN="0.0.0.0" ]
  • 23Installing and Basic Usage Instantiating Basic Usage – VMs Hands on! (Sunstone) ● Instantiate the template ● Deploy 2 VMs ● Leave the name blank ● Watch the transition PENDING  RUNNING ● In which host is running each VM? ● vnc ( root / password) ● ifconfig  configured using context ● migrate ● live-migrate ● ping the other machine
  • 24Installing and Basic Usage Main VM actions Basic Usage – VMs suspend VM state saved. Kept in the host. power off (--hard) Powers off a VM. Kept in the host. stop VM state saved. Taken to the system datastore. undeploy (--hard) Powers off a VM. Taken to the system datastore. reboot (--hard) Reboots the VM. delete --recreate Cleans the VM and moves it to PENDING. shutdown (--hard) Powers off a VM, cleans host and VM is removed from OpenNebula. delete VM is immediately destroyed regardless of state. Recommended only for oneadmin.
  • 25Installing and Basic Usage Other VM actions Basic Usage – VMs Hands on! (Sunstone) ● VM extended information tab ● Capacity - Resize VM capacity ● Storage - Attach new disk ● Network - Attach new nic ● create a new network  attach nic  reboot ● Snapshot ● create a file using VNC ● Take snapshot ● Modify the file ● Revert ● Placement ● Actions - Schedule action ● Template ● Log
  • 26Installing and Basic Usage Managing Users Basic Usage – Users Hands on! (Sunstone) ● Create new user: testuser / testpass ● Click on new user  Update Quotas ● Enforce 1 Max VMs  Add/edit quota ● Other possible options ● limit the use of a Datastore ● limit the use of an Image ● limit the use of a Network ● Apply changes! ● Create new ACL ● We can customize any rule extending the functionality provided by the Unix ownership/group/permissions schema.
  • 27Installing and Basic Usage Logs Basic Usage – Logging and Debugging ● Logs are kept under /var/log/one ● oned.log: all the information related to the oned daemon. Every request, actions and driver errors will be here. The verbosity is set by DEBUG_LEVEL in /etc/one/oned.conf ● sched.log:has all the information related to the placement of Virtual Machines. If a VM is not being deployed (kept in PENDING state), this log will explain why. ● <id>.log: the log of each VM. Also accessible through Sunstone. ● To activate driver logs, enable ONE_MAD_DEBUG in /etc/one/defaultrc
  • 28Installing and Basic Usage Other Features Other Key Features in OpenNebula ● Appliance Marketplace ● Catalog of virtual appliances ● Integrated with Sunstone ● Deployable in Private Cloud ● Hybrid Cloud Computing ● AWS connector that enables Cloud-Bursting ● Service Management (OneFlow) ● Automatic execution and scaling of multi-tiered applications ● Gain insight cloud applications ● Virtual Data Centers ● Fully-isolated virtual infrastructures ● Fedaration of multiple OpenNebula Zones ● Fine-Grained Accounting
