14 DAY TRIAL // Virtualization software VirtualBox has been promoted to version 4.3.10 Build 92957 today. Oracle adds a hefty dose of tweaks and fixes, as well as platform-specific enhancements for Mac, Windows, and Linux customers alike.
Oracle has carried out some more maintenance in the VMM department in order to improve the emulation of some MSR registers on certain host CPUs.
Single-stepping is fixed for real-mode guests and some I/O instructions, and a potential problem with COW pages is also addressed.
Graphics-wise, OS X customers get experimental native full screen support for Mountain Lion and Mavericks. The mini-toolbar minimize button has been removed, as it didn’t work under Mac OS X full screen mode.
Experimental HID LEDs synchronization for Windows and Mac OS X hosts is now available, and keyboard re-synchronization has been fixed. A potential crash when opening the preferences menu has been resolved too.
In the OVF department, a crash of the VirtualBox Manager is patched. 3D support gains several fixes, and saved states causing guest misbehavior are tweaked to offer more reliability.
Any storage bugs preventing the ability to compact differential snapshots under certain conditions are now gone, and a segmentation fault on Linux hosts is addressed. Guest behavior when a storage medium is attached or removed at VM runtime should be normal now.
On Mac OS X, the update also prevents local traffic from leaking to wire, according to the release notes. Some Windows additions are mentioned too: “fixed the environment for guest processes” and “fixed divide by zero exception with multiple guest screens under certain conditions.”
A Linux addition includes “install correctly on Ubuntu guest systems with a /usr/lib64 directory,” and an X11 addition is also highlighted by Oracle: “fix for the VBoxClient process not exiting correctly and consuming too much processor time.”
The requirements for using VirtualBox are varied. Depending on the platform/OS you’re running it on, you’ll need one or more extra things. It’s always good to have a decently-specced computer, so as to be able to share the memory, CPU, and storage with the virtual machine.
On Linux, for instance, you will need to install additional libraries to run VirtualBox. These include libxalan-c, libxerces-c, and version 5 of libstdc. Use the links below to grab the latest version of Oracle VM VirtualBox for your respective platform.
