What's technical difference between official virtualbox and VirtualBox-OSE? What's technical difference between official VirtualBox and VirtualBox-OSE? My scenario: I'm using Debian sid, it uses a `3.2.0-4` kernel. When you want to download VirtualBox, you have 3 options: * customized for distro: such as Debian, Fedora and so on, * `.bin`, and * source code. When you install a customized on recommended distro, It means on its kernel, you don't have any problem. When you compile a kernel or install a kernel that virtualbox.org doesn't support you get kernel oops. I posted it on the VirtualBox forum, but I didn't get an answer. Maybe I will just install on a certified kernel or install VirtualBox from repository. **Question:** I don't have any idea on VirtualBox-OSE, such as speed, memory, and etc. Do have experience on it?What's technical difference between official VirtualBox and VirtualBox-OSE?

Distribution-specifics aside there is no difference anymore. There were some closed-source drivers in the non-OSE package, but they have been moved to an extra package.

> Before version 4.0, there were two editions of VirtualBox: a full binary containing all features and an "Open Source Edition" (OSE) with source code. With version 4.0, there is only one version any more, which is open source, and the closed-source components have been moved to a separate extension pack. <
