[Qemu-devel] Virtualbox released under GPL2+

[Dan Shearer]

See http://www.virtualbox.org , a code release by InnoTek Systemberatung
GmbH. heard about this a few minutes ago. 

It's published under GPL2 or higher. Some bits (such as the recompiler)
are published under LGPL2.1 or higher. There's 464k lines of .cpp files,
487k lines of .h files.

Seems to have been exclusively Windows, then ported to Linux. (Includes
.exe files in the svn ;-) So far I notice lots of informative comments
and code attributions. Nothing in the docs directory yet (perhaps that's
in the user documentation on the website, haven't looked there yet.)
They're keen on testcases.

This is x86-on-x86 only from what I've seen of the source so far, with
an impressive number of x86 hosts including OS/2 and Darwin apart
from the obvious. 64bit as well as 32 hosts.

I haven't seen any dynamic translation, it is all ring-0 stuff I think. 

There's a licensing bug; the Linux kernel module says "GPL2 as per COPYING",
but COPYING is in fact GPL2+.

So far looks like a very tidy piece of work. Now to compile it and try
it out... the debugger looks like it might have a nice idea or two in
it.
