VirtualBox 4.1 Final released for Linux

VirtualBox 4.1 Final released for Linux

VirtualBox 4.1 final is released for Linux. It is a general-purpose full virtualizer for x86 hardware, targeted at server, desktop and embedded use. VirtualBox is a cross-platform virtualization application. What does that mean? For one thing, it installs on your existing Intel or AMD-based computers, whether they are running Windows, Mac, Linux or Solaris operating systems. Secondly, it extends the capabilities of your existing computer so that it can run multiple operating systems (inside multiple virtual machines) at the same time. So, for example, you can run Windows and Linux on your Mac, run Windows Server 2008 on your Linux server, run Linux on your Windows PC, and so on, all alongside your existing applications. You can install and run as many virtual machines as you like -- the only practical limits are disk space and memory.


VirtualBox is deceptively simple yet also very powerful. It can run everywhere from small embedded systems or desktop class machines all the way up to datacenter deployments and even Cloud environments.


This version is a major update. 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
