Hi, please do not use this VirtualBox Beta release on production machines. A VirtualBox Beta release should be considered a bleeding-edge release meant for early evaluation and testing purposes.
You can download the binaries here: http://download.virtualbox.org/virtualbox/2.2.0_BETA1/ See our 'VirtualBox Beta Feedback Forum' http://forums.virtualbox.org/viewforum.php?f=15 for more information about the Beta program. This version is a major update. The following major new features were added: * OVF (Open Virtualization Format) appliance import and export * Host-only networking mode * 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 guests * 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 (VT-x/AMD-V only) * VMM: significant speedup of certain Grub boot loaders (e.g. Solaris) (VT-x/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/usb-ohci/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 VT-x/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) Kind regards, Frank -- Dr.-Ing.
