● OpenNebula 5.0 Highlights
● MarketPlace
● Docker-Machine

3. Great A'Tuin
the turtle comes, swimming slowly through the interstellar
gulf, hydrogen frost on his ponderous limbs, his huge and
ancient shell pocked with meteor craters. Through sea-
sized eyes that are crusted with rheum and asteroid dust
He stares fixedly at the Destination.
Terry Pratchett - The Colour of Magic

4. OpenNebula 4.14
● Great A'Tuin
● Last one before 5.0
● Big Release (lots of changes)
● Compatibility Guide
4

5. Disk and image snapshotting
● Disk snapshots are a new entity
● Create, Revert, Delete
○ running, poweroff, suspended
● Subject to Quotas
● Monitor snapshot size
5

6. Disk and image snapshotting
● Can be exported to a new image
○ $ onevm disk-saveas
○ STATES: running, poweroff, suspended
○ --deferred is deprecated
● Persistent images can have snapshots
○ operations: flatten, revert, delete
● 3 implementations: Ceph, FS (plain files) and
Qcow2,
6

7. Disk Showback
● OpenNebula <= 4.12
○ CPU_COST
○ MEMORY_COST
● New DISK_COST is introduced
● It's a MB/hour metric
● Defined in the template
7

8. Recovery mechanisms for VMs
● OpenNebula is much more recoverable
● Any state can now be recovered
○ --success
○ --failure
○ --retry
○ --interactive
● FAILED state is now:
BOOT_FAILURE,
PROLOG_MIGRATE_POWEROFF_FAILURE, etc...
8

9. GPU Devices
● GPUs discovered by the monitorization
probes
● Can be added to a template
● Passthrough to the VM
● Subject to Quotas

10. Sunstone Rewrite
● Modularization
● Templates System

13. Cloning of running VMs
Provides the ability to clone a VM along with its
reference disks and networks.
$ onevm save <vmid> <name>
Clones the VM's source Template,
replacing the disks with live snapshots
of the current disks. The VM capacity and
NICs are also preserved
States: POWEROFF
13

14. Import of Existing VMs
● KVM, Xen, AWS, Azure and vCenter
● The monitoring probes detect wilds
● wild VMs can be imported
● The life-cycle can be managed
Limitations:
● Delete --recreate
● Undeploy (and Undeploy --hard)
● Migrate (and Migrate --live)
● Stop
14

15. Migration of VMs datastores
The System datastore of a VM can be migrated.
$ onevm migrate <range|vmid_list>
<hostid> [<datastoreid>]
15

16. Cold Attach / Detach of NICs and DISKS
These operations can now be executed in the
POWEROFF state.
$ onevm disk-attach <vmid>
Attaches a disk to a running VM. When
using --file add only one
DISK instance.
States: RUNNING, POWEROFF
valid options: file, image, target,
cache, prefix
16

17. Disk Resize
Possibility to resize the size of a VM disk when
instantiating the VM.
The Context packages resize the Guest when
starting.

18. The Road to 5.0
● Evolution result after 8 years + ~80 releases.
● 5.x series goal
○ Keep project vision and KISS adherence
○ Improve usability and refine current feature set
○ As much as possible, don’t break compatibility
○ Less used components to the add-on catalog

19. Some Highlights...
● User Interface
○ Improve input fields & views in Sunstone
● Virtual Network:
○ Security groups
○ Virtual routers
● Storage
○ Ceph as system Datastore & tuning
○ Integrated Marketplace*
○ Better LVM backend and new iSCSI
● Virtualization
○ Make possible more operations across VM states
○ Guest-Context improvements
* Discussed in this talk

20. ● Share as less as possible
● Tolerate big latencies
● Reduce coupling by sharing just: User & Auth information
● Federation of identities

22. Federation: Marketplace Demonstration
● Totally integrated, multiple uses cases, e.g.
○ Setup market for some groups
○ Set access control to appliances
● 5.0 shipped with two backends
○ Web server, using http transport to move images
○ S3 object store through Ceph S3 gateway
○ Public OpenNebula marketplace (client-only)
● Follows OpenNebula architecture:
○ Datastore specific operations
○ MarketPlace specific drivers
● Future plans to add more external drivers

23. Docker and OpenNebula
