Sun Microsystems heeft dinsdag de eerste bètarelease van versie 2.2 van VirtualBox uitgebracht. Dit programma kan worden gebruikt om een ander besturingssysteem in een virtuele omgeving te installeren. VirtualBox draait onder Windows 2000 en hoger, Mac OS X, Linux en Solaris en kan overweg met een groot aantal gastbesturingssystemen.



De software is in twee versies verkrijgbaar. De volledige versie heeft meer functionaliteit, zoals ondersteuning voor usb-poorten en het remote display-protocol, maar is alleen gratis voor privé-gebruik en evaluatiedoeleinden. Deze extra functionaliteit is namelijk closed source en ontbreekt in de andere versie, namelijk de opensource-uitvoering. Versie 2.2 bevat een aantal belangrijke verbeteringen. Zo is er ondersteuning voor Open Virtualization Format toegevoegd en is er onder andere usb-ondersteuning op OpenSolaris en OpenGL op Linux. Hieronder is het changelog van deze release te vinden:

    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
        * VMM: Fixed guru meditation when booting an AsteriskNow Linux VM
        * VMM: Fixed PGMPOOLKIND_FREE guru meditation
        * 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)
        * NAT: Blocked UDP packets cause crash
        * 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
        * Solaris guests: added xpg4/xcu4 dependency to the guest additions installer
        * 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
        * 3D support: close opengl subsystem for terminated guest applications
        * 3D support: fixed VM hangs when starting guests with 3D acceleration enabled
        * PXE: fixed boot hangs when hardware virtualization is used
