VirtualBox 4.3 Beta 1

VirtualBox è un software di virtualizzazione distribuito secondo i termini della GNU General Public License, per architettura x86 che supporta Windows, GNU/Linux e Mac OS X come sistemi operativi host, ed è in grado di eseguire Windows, GNU/Linux, OS/2 Warp, OpenBSD e FreeBSD come sistemi operativi guest.

Note di rilascio:

Please do NOT use this VirtualBox Beta release on production machines. A VirtualBox Beta release should be considered a bleeding-edge release meant for early evaluation and testing purposes.

Please do NOT open bug reports at but use our VirtualBox Beta Feedback forum to report any problems with the Beta. Please concentrate on reporting regressions since VirtualBox 4.2.16.

VirtualBox 4.3 will be a new major release. The following major new features were added:

VMM: major rewrite of the VT-x code including many bug fixes and performance improvements (for example bug #9659)
GUI: keyboard shortcuts management (input page of global preferences extended with possibility to edit general keyboard shortcuts for VirtualBox Manager and Virtual Machine)
GUI: extended messaging mechanism (new non-modal popup overlays used to show non-critical warnings and provide user with additional information)
GUI: video capturing support (bug #4766)
GUI: host touch devices support (GUI passes host touch-events to guest)
Emulated USB touch devices
VRDP: support for IPv6
NAT: experimental virtual router mode: several VMs are attached to the same internal network and share one NAT service (see the manual for more information)

In addition, the following items were fixed and/or added:

VMM: properly handle NMIs on Linux hosts with X2APIC enabled
GUI: update check uses https
GUI: lot of internal stuff rewritten (cleanup and bug-fixes)
Settings: global and per-VM default frontend configuration, useful to select the use of alternative VM frontends
Settings: limit depth of snapshot tree to 250 levels, as more will lead to decreased performance and may trigger crashes

Main: use the XDG standard configuration folder instead of .VirtualBox on systems where it is appropriate (bug #5099)
