VirtualBox 2.1
http://www.virtualbox.org/wiki/VirtualBox

virtualbox è un virtualizzatore gratuito per uso personale di Sun Microsystems (java e solaris per capirci...). prima di installare e acquistare gli ottimi parallels desktop o vmware fusion o partizionare con bootcamp può e deve essere preso in considerazione. non è detto infatti che non soddisfi le ns. esigenze di virtualizzazione da windows 98 a vista e per molte distro linux. da questa versione comincia il supporto per l'accellerazione 3D.

requisiti: un macintel e mac os 10.4 o superiore.

grazie per la segnalazione flash davvero molto utile!

ciao ciao

[maina]

mooolto interessante! grazie!

[Gas Gas]

Lo sto testando con linux e devo dire che è davvero sorprendente! Molto intuitivo e relativamente semplice da usare, sul mio macbook 2 duo 2GHz 1Gb RAM va che è una meraviglia!
A tutti coloro che intendono usarlo consiglio comunque una bella letturina del manuale

ciao ciao

VirtualBox 2.2: major update dell'8 aprile 2009

Major new features:

-OVF (Open Virtualization Format) appliance import and export (see chapter 3.8, Importing and exporting virtual machines, User Manual page 55)
-Host-only networking mode (see chapter 6.7, Host-only networking, User Manual page 88 )
-Hypervisor optimizations with significant performance gains for high context switching rates
-Raised the memory limit for VMs on 64-bit hosts to 16GB
-VT-x/AMD-V are enabled by default for newly created virtual machines
-USB (OHCI & EHCI) is enabled by default for newly created virtual machines (Qt GUI only)
-Experimental USB support for OpenSolaris hosts
-Shared folders for Solaris and OpenSolaris guests
-OpenGL 3D acceleration for Linux and Solaris guests (see chapter 4.8, Hardware 3D acceleration (OpenGL), User Manual page 70)
