Any idea where I find the backtrace info?  Couldn't see anything in the
build directory, or in the Console.app (to view various system/user logs).

BTW, I'm invoking qemu from the build directory with:

./x86_64-softmmu/qemu-system-x86_64 -accel hvf -m 4096
/Volumes/Windows/QEMU_VMs/Win7-Ultimate/hd0.img -net nic -net user

Android?  Is there a link with Android and macos?

Maybe qemu developers/users do not know that hvf is now available in
qemu?  Is it promoted so that people may become interested and try to
progress further development?  There must be some qemu developers that
have access to Macs and may even be Mac users too (just an assumption). 
Trying to pique their interest would be good ;-)
