[-- Attachment #1 --] Hello. some days ago I had a nice discussion with a qemu and haxm hypervisor developer that ended with a nice question and I would like to hear your opinions : ME : "HAXM was created to bring Intel Virtualization Technology to Windows and macOSusers" ; keeping in consideration that MacOS has some code of FreeBSD inside. Is the source code of HAXM freely available ? Are you able to port it to FreeBSD ? The idea is to accelerate qemu with HAXM on FreeBSD. Do you know someone that can and wants to do this ? qemu and HAXM developer : HAXM has been imported into pkgsrc/emulators/haxm ---> http://mail-index.netbsd.org/netbsd-users/2019/02/13/msg022207.html ME : wow. So,it exists for NetBSD but not for FreeBSD ? That's so bad. qemu and HAXM developer : Yes - https://github.com/intel/haxm. But it is not supported. I see no point in porting an unsupported solution to a new OS, thus dont think someone will want to port it. ME : So,it exists for NetBSD but not for FreeBSD ? That's so bad. qemu and HAXM developer : Yes, it supports NetBSD. ME : If NetBSD developers have been interested to port it,so why shouldn't FreeBSD ones be ? At least,in theory....after all,on FreeBSD qemu lacks the acceleration of a good hypervisor. qemu and HAXM developer : This can be solved by adding for example bhyve support to qemu. This should be a better solution, than porting an unsupported hypervisor. I'm not aware why FreeBSD developers didn't add it already, you may ask for the reason. How hard is it to write a version of bhyve that can accelerate qemu ? -- Mario.
