Download VirtualBox 4.1.18

Oracle has released the ninth update for version 4.1 of VirtualBox. VirtualBox can be used to install other operating systems in a virtual environment on a computer. In this way it is possible to use different operating systems on the same hardware side by side and at the same time. VirtualBox is available for Windows XP and above, Mac OS X, Linux, and Solaris, and is capable of many guest operating systems to turn.

The VirtualBox download contains only open source components. Some features, including support for USB 2.0 ports and the remote display protocol, are closed source and can be added by installing the VirtualBox Extension Pack. This one extension is covered by a personal use and evaluation license, i.e. puel. In version 4.1.18 the following changes and improvements have been made:

The following items were fixed and/or added:

• VMM: fixed VERR_REM_VIRTUAL_CPU_ERROR under rare conditions after the guest has been reset (bug #5164 and others)
• VMM: fixed host freezes with 64-bit guests on 32-bit Linux hosts (bug #10528)
• VRDP: added a workaround for rdesktop clients not properly updating the screen size when minimized
• AHCI: fixed a rare bug which can cause a guest memory corruption after the guest storage controler has been reset
• NAT: another attempt to fix crashes under rare conditions (Windows hosts only; bug #10513)
• Mac OS X hosts: addressed issues running Leopard / Snow Leopard (bug #10631)
• Linux hosts / Bridged Networking: fixed the problem with device driver unloading on kernels 3.2.18 and newer due to an invalid reference counter (bug #10624)
• Linux hosts / guests: Linux 3.5-rc1 fixes
• Linux Additions: the guest content was sometimes not properly updated (bug #9887)
• Solaris Additions: installer fix for X.org Server 1.11 and 1.12
