The following major new features were added: ‧ OVF (Open Virtualization Format) appliance import and export (see chapter 3.8, Importing and exporting virtual machines, page 55) ‧ Host-only networking mode (see chapter 6.7, Host-only networking, page 87) ‧ Hypervisor optimizations with significant performance gains for high context switching rates ‧ 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 ‧ OpenGL 3d acceleration for Linux and Solaris guests (see chapter 4.8, Hardware 3D acceleration (OpenGL), page 69) ‧ Experimental support for OS X 10.6 (Snow Leopard) hosts running both the 64-bit and the 32-bit kernel In addition, the following items were fixed and /or added: ‧ VMM: FreeBSD guest related fix for V86 flags (bug #2342) ‧ VMM: Fixed guru meditation when booting an AsteriskNow Linux VM (bug #2342) ‧ VMM: Fixed PGMPOOLKIND_FREE guru meditation (bugs #3356, #3431) ‧ VMM: Fixed Windows XP boot hang (guest PAE + nested paging only) ‧ VMM: Allow mixing of VT-x/AMD-V and software virtualization ‧ VMM: fixed extremely slow safe mode booting in e.g. Windows 2008 (VTx/ AMD-V only) ‧ VMM: significant speedup of certain Grub boot loaders (e.g. Solaris) (VTx/ AMD-V only) ‧ VMM: real-mode IOPL fix for DOS guests (VT-x only) ‧ VMM: fixed VT-x detection with certain BIOSes that enable VT-x, but don’t set the lock bit in MSR_IA32_FEATURE_CONTROL ‧ NAT: Truncated downloads with NAT (ftp) (bug #3257) ‧ NAT: Blocked UDP packets cause crash (bug #3426) ‧ USB: further reduced host CPU utilization for OHCI and EHCI; the “ VBoxInternal/Devices/usbohci/0/Config/FrameRate” CFG key is no longer necessary and no longer supported ‧ VRDP: fixed hangs when VRDP server is enabled or disabled in runtime ‧ X11 guests: show the guest mouse pointer at the right position if the virtual desktop is larger than the guest resolution (bug #2306) ‧ Solaris guests: added xpg4/xcu4 dependency to the guest additions installer (bug #3524) ‧ Linux hosts: do proper reference counting to prevent unloading the vboxnetflt module as long as this code is in use ‧ Linux installers: fixes for Slackware, Arch Linux and Linux from Scratch systems ‧ Windows installers: Combined installer executable which contains both (32- and 64-bit) architectures. ‧ VBoxManage: less cryptic command-line error messages ‧ VBoxManage: ’list vm’ commands now default to compact format ‧ Hard disks: improved immutable disk support to auto-reset diff file at VM startup ‧ GUI: enable the audio adapter by default for new VMs ‧ GUI: warn if VT-x/AMD-V is not operational when starting a 64 bits guest ‧ GUI: deactivate 64 bits guest support when the host CPU does not support VTx/AMD-V ‧ GUI: removed floppy icon from the status bar ‧ GUI: show build revision in about dialog ‧ GUI: fixed sticky status bar text ‧ GUI/Mac OS X: fixed disabled close button ‧ GUI: improved error dialogs ‧ 3D support: added opengl select/feedback support (bug #2920) ‧ 3D support: close opengl subsystem for terminated guest applications (bug #3243) ‧ 3D support: fixed VM hangs when starting guests with 3D acceleration enabled (bug #3437) ‧ PXE: fixed boot hangs when hardware virtualization is used (bug #2536) --
