2. 2 Agenda ● Introduction – Background ● OpenNEbula – Benefits – Features – Architecture – VM Life-Cycle ● Our Platform – Demo ● Future ● Reference ● Discussion

3. 3 Introduction ● For Virtualization Domain – Virtualization Maturity – Virtualization Application ● For Us – Need more Machines for test – Effective Management VM in Cluster ● Xen Cluster Management – ROCKS – OpenNEbula – Ganeti

4. 4 Background ● Xen's Philosophy – Para-Virtualization ● Xen Architecture ● Xen Networking – Virtual Ethernet Interface – Security

5. 5 OpenNEbula ● Transform a distributed infrastructure into a flexible virtual infrastructure ● OpenNEbula is a distributed virtualization layer – Extend the benefits of VMMs – Decouple the service from the physical infrastructure OpenNEbula Layer Source: OpenNEbula

6. 6 Benefits ● Workload Balance ● Server Consolidation ● Dynamic resizing ● Dynamic Cluster Partitioning ● Support for Heterogeneous Workload

7. 7 Features ● Efficient Resource Management ● 3 rd Party Software Integrate ● Open and Flexible Architecture ● Failure Tolerance ● Ease of Installation and Administrator ● Open Source Sofware ● OpenNEbula is an Active Project

8. 8 Architecture OpenNEbula Operation OpenNEbula Architecture Source: OpenNEbula Source: Ruben S. Montero

9. 9 XML-RPC ● XML-RPC 是一個使用 HTTP 作為傳輸協定、並使用 XML 作為資料編碼方法的遠端程序呼叫 (RPC) 。 ● XML-RPC 被設計的盡可能的簡單讓複雜的資料結構可 以被傳送、處理和傳回。藉由建立這樣的標準可以讓在 不同的作業環境中的軟體經由網際網路互相對彼此進行 程序呼叫。

10. 10 Virtual Machine Life-cycle Source: OpenNEbula

11. 11 Our Platform DRBL Server Xen Cluster Xen Hypervisi or OpenNEbula Node Xen Hypervisi or Node... VM... VM

12. 12 Demo ● Demo 1 – Add nodes to OpenNEbula pool – Test onehost functions ● Demo 2 – Submit VMs – Deploy VMs to nodes – Test onevm functions

13. 13 Future ● For us – Application of 3D Fly (virtual PCI graph card) – Virtual testbed (Hadoop server, Computing node, Development Platform) ● GUI ● Live Migrate ● High Performance FS + Shared Storage – gfs + GNBD
