For now i want to get hypervisor framework merged into QEMU in required license. I did offer to open source everything needed from anka to the make QEMU being able to run any os using hypervisor.framework. Having such code as open source will certainly help anyone who is going to work more on QEMU HVF so it would be great. Sergio, in the meanwhile can you post v3 with an extra patch after 2/13 that: - moves the task switch code to a new file with v2-only header - changes all v2-only or v2-v3 headers in HVF files to v2-or-later Then Izik and Frank can reply with their Signed-off-by to that extra patch.
