Hello all, I suspect that the answer to my question is 'no', but would like to get a confirmation. Is there functionality in the Main API (which I'm accessing through COM on Windows) for byte-level read/write access to vdi files?
My goal is to write my own boot loader just for experimentation, so I need an easy way of modifying disk sectors outside of the VM. The goal is to have a python script that would update the boot loader code after I make changes to it, configure some VM parameters, and then start the VM. I got almost everything working, including getting access to the right IMedium interface for the hard drive, but as I searched for how to write data to it after calling lockWrite, I found nothing relevant. Am I correct in assuming that the API will only protect the image from modification by other clients, but actually changing disk contents will require me to open the .vdi file and then parse the internal metadata myself? If so, where can I find the documentation for vdi file layout? I did search, but didn't find anything. If there is no documentation, can you point me to the relevant portions of the VirtualBox code so I can convert the parts that I need to python? I only need a subset of the functionality that deals with fixed-size images and no snapshots. Thanks for your help, Max _______________________________________________ vbox-dev mailing list vbox-dev@virtualbox.org http://vbox.innotek.de/mailman/listinfo/vbox-dev
