1. CLUG TALK Virtualbox Tuesday, 29 September 2009 One of the Jonathans

2. Virtualization What is Virtualization?

3. Virtualization Different Kinds of Virtualization: Virtual machine (VM), a software implementation of a machine (computer) that executes programs like a real machine Platform virtualization, which separates an operating system from the underlying platform resources Full virtualization, sensitive instructions replaced by binary translation or trapped by hardware - all software can run in the VM, e.g. IBM's CP/CMS, VirtualBox, VMware Workstation Hardware-assisted virtualization, CPU traps sensitive instructions - runs unmodified guest OS; used e.g. by VMware Workstation, Xen, KVM Partial virtualization, for specific applications rather than the operating system Paravirtualization, a virtualization technique that presents a software interface to virtual machines that is similar, but not identical, to that of the underlying hardware, thereby requiring guest operating systems to be adapted Operating system-level virtualization, a method where the operating system allows for multiple user-space instances (virtual hosting, chroot jail + resource management)

4. Hardware Virtualization Intel: Intel VT-x Some P4, P-D, Core 2, Atom CPUs AMD: AMD-v Opteron 2G, Athlon 64X2 Socket AM2 family CPUs

5. Applications Consolidating Servers Running Legacy Applications Testing Build Environments

6. Some Benefits Less Hardware Power Savings Redundancy Performance

7. Where does Vbox come from? Originally created by German software company Innotek Bought by Sun Microsystems, now part of its Sun xVM virtualization platform Sun Microsystems is now owned by Oracle
