QEMU has a built-in policy that adds rules for every conceivable
function that QEMU might need to execute. Given that is quite
broad, the security benefit from seccomp enablement is quit low
IMHO
Base code and (active) devices would each have to report what syscalls
they need so this list could be reduced to the minimum ...
