The following major new features were added: Support for cloning of VMs (bug #5853, see the manual for more information): full clones can be created through the GUI and VBoxManage, linked clones only through VBoxManage GUI: enhanced wizard for creating new virtual disks GUI: new wizard for copying virtual disks GUI: keep the aspect ratio in scale mode (Windows and OSX hosts only; bug #7822) VMM: raised the memory limit for 64-bit hosts to 1TB Experimental support for PCI passthrough for Linux hosts, see the manual for more information Windows guests: Experimental WDDM graphics driver, supporting Windows Aero (bug #4607) and providing Direct3D support using a cleaner approach (no need to install the guest drivers in Safe Mode anymore) Guest Additions: status of modules and features can now be queried separately by the frontends Networking: new network attachment mode "Generic Driver", which offers an open plugin architecture for arbitrary and separately distributable virtual network implementations Host-only Networking: fixed host crash in kernels prior to 2.6.29 New Networking Mode UDP Tunnel: allows to interconnect VMs running on different hosts easily and transparently, see the manual for more information Experimental support for SATA hard disk hotplugging available with VBoxManage Solaris hosts: New Crossbow based bridged networking driver for Solaris 11 build 159 and above In addition, the following items were fixed and/or added: VMM: more SMP timer fixes VMM: fixed sporadic recompiler crashes with SMP guests VMM: many small fixes GUI: when reverting to a snapshot, ask for taking a snapshot of the current state GUI: added a View menu GUI: added a setting for the promiscuous mode policy for internal networks, bridged networks and host-only networks GUI: added slider for setting the CPU execution cap allowing to limit the amount of CPU time spent for the execution of the guest, see the manual for more information. GUI: the VM description is editable during the runtime of a VM (bug #1551) GUI: added proxy settings (bug #2870) GUI: made the number of SATA ports configurable GUI: decrease time before showing the VM configuration dialog VBoxManage: more convenient configuration of storage controller attachments by automatically determining the port or device parameter when a storage controller has only one port or device per port VBoxManage: changed syntax of the guestcontrol command group, fixed various bugs, removed obsolete options VBoxBalloonCtrl: new service for automatic dynamic adjustment of the balloon size for running VMs Settings: machine names and snapshot names are not allowed to be a valid UUID Settings: provide better diagnostics if a single medium is used twice in a VM configuration Settings: provide better diagnostics for errors in medium create/merge/clone operations, and fix memory leaks in error cases Storage: ATA/SATA drives can be marked as non-rotational, i.e. the guest OS will detect them as a SSD if supported, which can improve performance Storage: virtual CD/DVD images will be detached if the guest ejects the medium, unless the drive is marked to handle ejects only on a temporary basis Storage: the medium UUID can be changed again when attaching a medium for the first time, which allows using images which are exact duplicates including the UUID Storage: fixed possible data corruption under certain circumstances with VHD and Parallels images (bug #9150) Storage: fixed unnecessary expansion when cloning differential images in VDI format Storage: fixed detection code to handle empty files for VDI and VMDK format Storage: fixed access to CD/DVD images beyond 4GB when using the SATA controller (bug #8592) Floppy: several bugs have been fixed Floppy: make it possible to unmount a host floppy disk (bug #6651) BIOS: disk-related structures are now checksummed correctly (bug #8739) USB: many fixes for the Windows USB host driver NAT: reduced memory footprint Networking: fixed the problem with segmentation offloading when several VMs are transmitting in parallel Networking: workaround for a bug in wireshark when operating directly on a capture file created by VirtualBox Serial: announce the serial devices in the ACPI tables to make Windows guests find the virtual hardware (bug #7411) VRDP: support for TLS connections (see the manual for more information) VRDP: support for multimonitor client configurations with MS RDP clients VRDP: fixed a rare screen corruption 3D support: fixed GL_VERSION string for different locales (bug #8916) Webservice: fixed timeout handling with HTTP 1.1 keepalive, and be more robust when connections fail VBoxSVC: fixed regression when several clients trigger autostart simultaneously Main: fixed incorrect handling of the medium location for media which are not file based (e.g. iSCSI), which resulted in confusing location values in many places JAX-WS client bindings: fixed resource leak Sources: fixed USB 2.0 support using extension packs for non-official builds Mac OS X hosts: fixed non-VT-x mode on Lion hosts Windows hosts: fixed copy'n'paste in the GUI and for the VM window (bug #4491) Windows hosts (64-bit only): enabled removing of all mediums when removing a VM Windows hosts (64-bit only): enabled live snapshot deletion Windows hosts: use native controls in the installer (bug #5520) Solaris hosts: fixed preemption issue with Solaris 11 hosts (builds 166 and above) Solaris hosts: better control of USB device access on Solaris 11 hosts Guest Additions: improved driver installation on Windows guests Guest Additions: fixed high CPU usage while executing guest programs from the host Solaris Additions: fixed automounting of shared folders (bug #8014) www.oracle.com Contact – Privacy policy – Terms of Use
