Coding your own Guest Additions

[Smackey's dad]

Is there documentation on how to write your own Guest Additions

Moved to OSE.

I don't think there is a comprehensive and detailed howto, so I can only point you to the technical docs.

About supporting other kind of hardware, CPU, such as : Router and network device...

How would I go about this ?
What is involve ?

Should I look into the source code ? and where ?
In other words where does it (in the code) visualize the hardware in the guest?

I just need a pointer of where to start looking on how to do this... I may be able to figure out the rest.

Thank you for your help.

There isn't a manual but usually the first place to look after is at src/VBox/Additions/common/VBoxGuest/. Use the Linux driver as a starting point. The Guest Additions driver is the guest part of the guest/host interface. Guest services (e.g. VBoxService) access this driver via IOCtl.
