The document discusses OpenNebula, a virtualization and cloud infrastructure management platform, highlighting its key features, flexibility, and integration capabilities with various hypervisors and storage backends. It also introduces OneInsight, a load visualization tool designed to enhance monitoring and decision-making for virtual machine management. The presentation emphasizes the seamless integration of these tools and their effectiveness in optimizing resource allocation and capacity planning.

2. Background
Virtualization, Virtual Machines (VM), Container
Virtual Machines Managers: Xen, KVM, VirtualBox,
VMware ESXi, LXC, Docker
Virtual Infrastructures, IaaS: OpenNebula,
Eucalyptus, OpenStack, CloudStack, Ganeti,
Amazon EC2, Ikoula

3. What is OpenNebula
Virtual infrastructure manager, and also IaaS toolkit
Simplicity, Flexibility, Robustness, Powerfulness as key design
principles
Marketplace

4. Positioning Within the
Ecosystem

5. History

6. OpenNebula Features
Hypervisor agnostic (Xen, KVM, WMware)
... easy integration process for new driver
Wide range of storage backends (FS, VMFS, LVM, CEPH,
GlusterFS, MooseFS)
... various images transfer drivers (scp, qcow2, shared)
CLI, GUI, and APIs (XML-RPC, OCA, EC2, OCCI)

7. More Features
Virtual data centers (aka Zones) for Multitenancy
* multiple instances of OpenNebula,
* acting as fully isolated virtual infrastructures,
* but managed from a central point
Monitoring (Hosts, VMs)
* Built-in collector: gathers information from the hypervisors
* Ganglia add-on: gathers information from Ganglia
All features: http://opennebula.org/about/key-features/

8. OpenNebula & CentOS
"A Perfect Match", Karanbir Singh
http://fr.slideshare.net/opennebula/centos-and-opennebula-
a-perfect-match
Official repository for CentOS
* http://wiki.centos.org/Cloud/OpenNebula/QuickStart
Official OpenNebula's demo stack based on CentOS
* http://opennebula.org/tryout/
* Let's see a demo?

9. Built-in Monitoring
Easy integration, works out-of-the-box
Scalability problems due SSH polling
* improved in 4.4 with a push model
Limited visualization

10. Monitoring with Ganglia
Scalable, ...thanks to the Ganglia architecture
Complex integration,
... installing and configuring gmond on each host,
... and custom cron scripts to gather info about VMs
Better visualization

11. oneInsight Load Visualization
Load mapping regarding various metrics:
... CPU, Memory, storage, Running VMs, etc

12. oneInsight In a Nutshell
Simple, accurate, and comprehensible load charting,
... eases your decisions regarding VM migrations and capacity
upgrading if necessary,
... saves you a lot of time in comparing host loads
Simple Integration: Lightweight HTML/Javascript stack
Works out-of-the-box on any Linux distro, subject to have a:
... valid OpenNebula user account,
... curl command line interface,
... Bash interpreter,
... cron job scheduler,
... Web server like Apache and Nginx, even Python
SimpleHTTPServer just works fine
