  • Added support for Intel Nehalem virtualization enhancements (EPT and VPID; see user manual, chapter 1.2, Software vs. hardware virtualization (VT-x and AMD-V), page 10))
  • Experimental 3D acceleration via OpenGL (see user manual, chapter 4.8, Hardware 3D acceleration (OpenGL), page 66)
  • Experimental LsiLogic and BusLogic SCSI controllers (see user manual, chapter 5.1, Hard disk controllers: IDE, SATA (AHCI), SCSI, page 70)
  • Full VMDK/VHD support including snapshots (see user manual, chapter 5.2, Disk image ?les (VDI, VMDK, VHD), page 72)
