Hello, Mr. Frank Yang was the guy at Google that introduced the HVF port to Google's Android Emulator QEMU branch. Frank, in this thread we are discussing the licensing issue with the HVF files (their being GPL v2-only). Paolo from Red Hat was asking to Veertu developer Izik Eidus if the code in Veertu derived only from QEMU, Bochs and other GPLv2+ or LGPL software. Because the code at Google was itself derived from Veertu, I'd imagine the same licensing terms would apply in your case. Any light you can throw over this issue would be much appreciated.
Thank you.
