Historique des changements, page 247. 11 1 Premiers pas 1.1 À quoi sert la virtualisation ? Les techniques and les fonctionnalités offertes par VirtualBox servent dans plusieurs scenari : • Lancer plusieurs VirtualBox même sur du vieux matériel où ces fonctionnalités ne sont pas présentes. Les détails techniques sont expliqués a chapitre 10.3, Virtualisation matérielle vs. logicielle, page 213. • Suppléments

in chapter 15, Change log, page 270. 11 1 First steps 1.1 Why is virtualization useful? The techniques and features that VirtualBox provides are useful for several scenarios: • Running multiple operating algorithm allowing a higher com- pression ratio than standard RDP bitmap compression methods. It is possible to increase the compression ratio by lowering the video quality. The VRDP server automatically detects defined as a value from 10 to 100 percent, representing a JPEG compression level (where lower numbers mean lower quality but higher compression). The quality can be changed using the following command: VBoxManage
