3. 1. Introduction Why Virtualization in cluster or grid?
Virtualization and Grid Computing heading in similar direction (from GIRD METER)
Grid, Virtualization Get Cliser (from InternetNews)
Matt Haynos (IBM director of Grid computing strategy and technology)
Pretty simpile-> Grid IS Virtualization
Grid is a logical extention of virtualization to encompass both workload and information across a distribution infrastruction.
Bob Monkman: Cluster Virtualization

4. 2. Virtualization Technology

5. Virtualization Classification
Full Virtualization
Vmware, Qemu, MS virtual PC, VirtualBox
Para-Virtualization
Xen
OS-level Virtualization
OpenVZ, Virtuozzo

6. Xen Architecture

7. KVM (Kernel-based Virtual Machine)

8. Check CPU & Kernel

9. 3. Demo

10. 4. Xen vs. KVM

11. Landscape
Architecture

12. Feature Comparison Xen KVM Rich server feature set
Guest save/restore, live migration
• RAS (hotplug CPU/memory/devices)
• IO virtualization infrastructure
• Secure isolation and QoS control
• Multiple architectures support, e.g. IA-32, IA-64
A viable Linux virtualization solution
Thin Hypervisor
Inherits the Linux kernel features and hardware support
Limited complexity due to VMX dependency
Inherits the Linux kernel developer base
Linux native admin tools work

13. 4. Application Gird Globus Virtual Workspaces egee's LCG application
glite's component virtualization

15. Content Problem-> LCG-2.4 (Large Installation & hard Training)
Object-> Scenario virtualization software can prove to be useful
Virtualization-> Cambridge Xen
Performance-> UML 75% vs. Xen 90~95%
Migrate-> live migrate

16. Grid in a Box: Components

17. 6. Impact to me Virtualization for our Cluster Application
Powerful SMP (Kerrighed platforem)
Central management
Dynamic migrate vm to idle node
Kerrighed with Xen
Q1. Kernel version ?
Kerrighed with KVM
Q1. Krg migrate command ? ($ migrate pid nodeid)
