Sergio: Have you or Paolo had any contact with the Veertu or Google
authors about your Hypervisor.framework project?  If you're already in
contact with them you could raise the issue and ask them to join this
email thread.


Izik, Vincent (assuming you are the right person to contact at Google), can
you reply to Daniel and Stefan?

Sergio worked on completing the QEMU port to Hypervisor.framework. The
hvf-all.c file that Daniel pointed out as v2-only is derived from kvm-all.c
and hax-all.c, and should be under v2-or-later license. The others seem to
be either original or derived from Bochs, which is LGPL, so they could be
LGPL or GPLv2+.

Thanks,

Paolo


There are benefits to having this code upstream.  If they ever want to
rebase on qemu.git there will be less work for them.
