InnoTek VirtualBox, the only full x86 virtualizer that is also available as open-source, was released on January 15, 2007, not even a month ago. Today InnoTek released version 1.3.4, the first significant update with over 800 improvements based on feedback from the user community.

Now Ubuntu has decided to integrate the open-source VirtualBox kernel module into the official Ubuntu Linux kernel sources starting with the upcoming Ubuntu 7.04 ("Feisty Fawn") to further improve integration with VirtualBox, which will be hosted in Ubuntu's software repository. Mark Shuttleworth, founder of the Ubuntu project, said of VirtualBox's integration with Ubuntu: "Until now the open-source community has relied on closed-source software for full virtualization. With VirtualBox, InnoTek has donated a professional virtualization technology to the pool of open-source software. We are pleased that InnoTek has chosen to provide support for Ubuntu, and we will be working with them to make VirtualBox available to all Ubuntu users."

"We are very excited about the tight integration of VirtualBox with Ubuntu", says Achim Hasenmueller, director of InnoTek. "This makes it as easy as possible to install VirtualBox on Ubuntu. We have chosen Ubuntu as the first and primary distribution to ship with VirtualBox because Ubuntu is all about combining simplicity and power, which perfectly matches what we are aiming for with VirtualBox."
