Oracle extends open source VirtualBox 4.0

From the ‘Hypervisor that Rocks‘ files:

Among the many technologies that Oracle acquired from Sun is the VirtualBox virtualization technology. This week Oracle officially release VirtualBox 4.0, improving performance, usability and scalability.

And guess what? The core product remains licensed under the GPLv2  – but wait there is a catch.

Starting with this new VirtualBox 4.0 release, Oracle has reorganized the project so there is a base release and then there are Extension Packs, that extend VirtualBox and aren’t necessarily open source either.

For the VirtualBox 4.0 release Oracle there is now one extension pack which includes three new pieces of functionality, a virtual USB 2.0 (EHCI) device,VirtualBox Remote Desktop Protocol (VRDP) support and Intel PXE boot ROM with support for the E1000 network card.
