EmuCR: VirtualBoxVirtualBox v4.3 Beta 1 is released. VirtualBox is a general-purpose full virtualizer for x86/x64 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.

VirtualBox v4.3 Beta 1 Changelog:
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

In addition, the following items were fixed and/or added:
VMM: properly handle NMIs on Linux hosts with X2APIC enabled

GUI: lot of internal stuff rewritten (cleanup and bug-fixes)
