VirtualBox Guest Drivers

[GoogleCodeExporter]

VirtualBox Guest Drivers are mandatory to :
- Implement shared directory with host
- Have Hardware OpenGL

Working on my local tree.

Procedure :
- Download vbox guest additions
- Go to VBoxGuestAdditions-x.y.z/src/vboxguest-x.y.z
- Issue "make BUILD_TARGET_ARCH=x86 KERN_DIR=/path/to/android/kernel"
- If compilation OK, you'll have kernel modules vboxguest.ko vboxsf.ko 
vboxvideo.ko which will have to be loaded at android startup

What license are the Guest Additions under? If GPL, I wonder if AOSP would be 
willing to consider them for inclusion in external.

Huh, you're right - it's GPL...
https://forums.virtualbox.org/viewtopic.php?f=5&t=11951
That means there's little chance AOSP accepts inclusion...
And that also would mean OpenGL Hardware acceleration (which needs Guest 
Additions) can't be included.
I'll post a question on that on Android forums.

If it's all kernelspace (e.g. kernel modules) it should be fine though... 
almost everything else on the kernel side is GPL after all.

For the basic "Guest additions" part there's only kernel modules.
But when it will come to Hardware OpenGL there's user-space libs...

Could you share the source for openGL of android-x86 VMWare(or VirtualBox)?
I'm trying, but I don't know how to work...

I am trying to compile guest additions for VirtualBox on Lollipop branch. But I 
get invalid module format when I try to load the module using modprobe., 

Here are the steps I used to compile the guest additions: 

1. VirtualBox 4.3.20
2. Generated kernel headers for androidx86 kernel
3. Configured Androidx86 build using " ./configure 
--with-linux=androidx86/kernel --disable-libvpx --disable-xpcom 
--disable-python --disable-java --disable-sdl-ttf --disable-alsa 
--disable-pulse --disable-opengl --disable-docs --disable-devmapper 
--disable-udptunnel --disable-hardening --build-headless"
4. Compiled x86 linux image: kmk additions-build-linux.x86
5. compile kernel modules from the generated VBoxGuestAdditions-x86.tar
6. I tried loading the modules using the modprobe but I get invalid module 
format. 

Can you please help me on how to generate the loadable modules correctly?
