Use virtualization software? Check out VirtualBox 2.2.2!
Use virtualization software? Check out VirtualBox 2.2.2, which adds some exciting new features:
- Support for 64-bit guests on 32-bit host operating systems. Testing a 64-bit desktop is now much easier thanks to VirtualBox supporting 64-bit guests on 32-bit hosts. It’s pretty impressive that this is even possible!
- Experimental 3D acceleration via OpenGL. Don’t get too excited about 3D acceleration yet. For now only OpenGL on a 32-bit Windows guest is supported. DirectX support is planned, which means that 3D gaming in a VM could become possible.
- New Host Interface Networking implementations for Windows and Linux hosts with easier setup. Host interface networking couldn’t be easier in this release. No setup is required on the host or guest!

- OVF (Open Virtualization Format) appliance import and export (see chapter 3.8, Importing and exporting virtual machines, User Manual page 55)
- Hypervisor optimizations with signi?cant 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
- Added C API in addition to C++, Java, Python and Web Services
