Download VirtualBox 3.2.6

Oracle has released version 3.2.6 of VirtualBox, the third update before the version 3.2.0 released in mid-May. This program can be used to install other operating systems on a computer in a virtual environment. That way, different OSes can be used on the same hardware. VirtualBox is available for Windows 2000 and above, Mac OS X, Linux, and Solaris, and can handle a variety of guest operating systems†

VirtualBox is available in two versions. The full version has additional functionality, such as support for USB ports and the remote display protocol, but is only free for private use and evaluation purposes. The extra functionality is closed source and is therefore not present in the open source version. New in version 3.2.0 include the ability to run Mac OS X as a guest OS and dynamically adjust memory size. In version 3.2.6 the following changes and improvements have also been made:

The following items were fixed and/or added:

• VMM: fixed host crash when running 64-bit guests on 32-bit hosts with certain Intel CPUs (VT-x only; bug #6166†
• VMM: allow 64-bit SMP guests on 32-bit hosts (VT-x and AMD-V only; does not apply to Mac OS X, which already supports it)
• VMM: fixed Guru mediation if guests with more than 2GB are booted with VT-x/AMD-V disabled (bug #5740†
• VMM: fixed TR limit trashing (VT-x and 64-bit host only; bug #7052†

• NAT: fixed potential memory leaks
• NAT: increased the size of the memory pool for 16K Jumbo frames (performance tweak)
• NAT: allow to link/unlink the network cable even if the VM is currently paused
• E1000: disconnect cable was not properly handled if the NIC was not yet initialized by the guest
• OVF: export performance optimization
• OVF: upgraded OS type definitions to CIM 2.25.0 so that Windows 7 and other OSes are now tagged correctly on export
• Settings: the setting for disabling the host I/O cache was sometimes not properly saved
• Settings: save machine state into XML correctly even when snapshot folder has been changed to a non-default location (bug #5656†
• USB: allow the guest to disable an EHCI port
• USB: find a valid language ID before querying strings (bug #7034†
