The first beta for Virtualbox 3.2.0 Beta 1 is available for download now. According to the annoucement post in the Virtual Box forum there are a lot of interesting changes in the next release:
  • renaming VirtualBox to "Oracle VM VirtualBox"
  • Experimental support for Mac OS X guests
  • Memory ballooning to dynamically in- or decrease the amount of RAM used by a VM (64-bit hosts only)
  • CPU hot-plugging for Linux (hot-add and hot-remove) and certain Windows guests (hot-add only)
  • New Hypervisor features
    • with both VT-x/AMD-V on 64-bit hosts, using large pages can improve performance
    • also, on VT-x, unrestricted guest execution is now supported (if nested paging is enabled with VT-x, real mode and protected mode without paging code runs faster, which mainly speeds up guest OS booting)
  • Support for deleting snapshots while the VM is running
  • Support for multi-monitor guest setups in the GUI
  • USB tablet/keyboard emulation for improved user experience if no Guest Additions are available
  • LsiLogic SAS controller emulation
  • RDP video acceleration
  • NAT engine configuration via API and VBoxManage
  • Guest Additions: added support for executing guest applications from the host system
  • OVF: enhanced OVF support with custom namespace to preserve settings that are not part of the base OVF standard
