  1. Virtualisation Technology MLUG – 29th August, 2008

  2. Virtualisation • Term commonly used for many years • Abstraction of hardware resources • Partial Virtualisation • Full Virtualisation • Operating System-level Virtualisation • Application Virtualisation (Emulation)

  3. Partial Virtualisation • Partial simulation of hosted hardware • Not the same idea behind modern virtualisation • Limitations of running software on partial virtualisation led to Full Virtualisation

  4. Full Virtualisation • Implemented in 1967 - IBM CP40(VM family) • Complete simulation of host hardware • Indistinguishable from host capabilities • Originally for distributed terminal-style computing

  5. Full Virtualisation • Full virtualisation on x86 platform in 05/06 • All current “standard” virtualisation platforms are examples of Full Virtualisation • Some vendors such as VMware claimed full virtualisation prior to this, but technically incorrect • Virtual machines by definition are unallowed to “pierce the virtual machine”

  6. OS-level Virtualisation • “Containers” • Often used in Virtual Hosting environments • Very low overhead • Examples of OS-level Virtualisation are • Chroot (basically) • OpenVZ • Parallels Virtuozzo • FreeBSD Jail

  7. Emulation • I know that you know what this is • Engines designed to execute applications on platform (instruction set) that it was designed on • Play your Super Nintendo games on your PC 

  8. Desktop Virtualisation • Examples • Parallels Desktop for Mac • Parallels Workstation • VMware Fusion • VMware Player/Workstation

  9. Server Virtualisation • Examples (OS-level Virtualisation) • OpenVZ • Virtuozzo • Jail • Linux V-Server • Examples (Full Virtualisation) • VMware GSX (old) • VMware Server (v2 RC2 is latest version) • This is what I will demonstrate

  10. Enterprise Virtualisation • VMware ESX • Pretty much the standard • Very low overhead optimised host O/S • Hardware requirements are strict • Found in large corporate facilities
