VirtualBox 4.0.0.69151

Oracle - (Open Source)

VirtualBox is an easy and elegant solution for those who want to control a computer from another computer.

VirtualBox offers virtualize your operating system (OS) guests on a host machine. Called hypervisor, the application supports Windows OS X, Linux, Mac, Solaris, FreeBSD, etc.. as host, Mac OS X missing the call as a guest.

It also includes a remote access via HTTP protocol, convenient for demonstrations on a clean system.Â The ability to manage multiple states of the system is particularly interesting and its interface is very simple.

Virtualization solutions allow installing an operating system on a virtual machine using the resources of the host PC , thus enjoying very good performance. In the genre, several solutions are known for their ease of use, such as VMware Workstation , Parallels Desktop or Microsoft Virtual PC 2007 SP1.

A virtual machine is a useful way to use two operating systems simultaneously and harmless to the host computer. There is the possibility to install Linux on a virtual machine on Windows and vice versa .

- Support for creating and starting .vbox desktop shortcuts (bug #1889)
- The VM list is now sortable
- Machines can now be deleted easily without a trace including snapshots and saved states, and optionally including attached disk images (bug #5511; also, VBoxManage unregistervm --delete can do the same now)
- Built-in creation of desktop file shortcuts to start VMs on double click (bug #2322)
* VMM: support more than 1.5/2 GB guest RAM on 32-bit hosts
* New virtual hardware:
- Intel ICH9 chipset with three PCI buses, PCI Express and Message Signaled Interrupts (MSI); see chapter 3.4.1, â€œMotherboardâ€ tab, see the manual for more information
- Intel HD Audio, for better support of modern guest operating systems (e.g. 64-bit Windows; bug #2785)
* Improvements to OVF support (see chapter 1.12, Importing and exporting virtual machines, see the manual for more information):
- Open Virtualization Format Archive (OVA) support
- Significant performance improvements during export and import
- Creation of the manifest file on export is optional now
- Imported disks can have formats other than VMDK
* Resource control: added support for limiting a VMâ€™s CPU time and IO bandwidth; see chapter 5.8, Limiting bandwidth for disk images, see the manual for more information
* Storage: support asynchronous I/O for iSCSI, VMDK, VHD and Parallels images
* Storage: support for resizing VDI and VHD images; see chapter 8.21, VBoxManage modifyhd, see the manual for more information.
* Guest Additions: support for multiple virtual screens in Linux and Solaris guests using X.Org server 1.3 and later
* Language bindings: uniform Java bindings for both local (COM/XPCOM) and remote (SOAP) invocation APIs

# In addition, the following items were fixed and/or added:

* VMM: Enable large page support by default on 64-bit hosts (applies to nested paging only)
* VMM: fixed guru meditation when running Minix (VT-x only; bug #6557)

* Floppy: support readonly image files, taking this as the criteria for making the medium readonly (bug #5651)
* Audio: fixed memory corruption during playback under rare circumstances
* Audio: the DirectSound backend now allows VMs to be audible when another DirectSound application is active, including another VM (bug #5578)
