What’s New in VirtualBox 4.1.0


VirtualBox is one of my favorite desktop virtualization software. Oracle is getting ready to release the next major updated version of this product, as of today it is in beta stage.




Below are the main updates and changes in VirtualBox 4.1.0
Support for cloning of VMs  (This was one of the missing feature Virtual Box had earlier. Creating a new virtual machine by using cloning an existing virtual machine was a difficult job in earlier versions.)
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
Windows guests: Experimental WDDM graphics driver
Guest Additions: modules and features now are represented as facilities to have a common interface for frontends
Networking: new network attachment mode “Generic Driver”, which offers an open plugin architecture for arbitrary and separately distributable virtual network implementations
New Networking Mode UDP Tunnel: allows to interconnect VMs running on different hosts easily and transparently
Experimental support for SATA hotplug added. Currently only supported for hard disks and only with VBoxManage.
I got time to check some of the new features in VirtualBox 4.1.0 and decided to share with my readers.
