Everything else is fine. Having a fallback would still be nice, even if it is just the fixed string "qemu". Starting a fresh build without installing it first is common while developing. take care, Gerd

The first argument of the executable was used to get its path, but it is not reliable because the executer can specify any arbitrary string. Use the interfaces provided by QEMU and the platform to get those paths.
