It's true that the pc-i440fx-4.0 machine type exists, but it's in
the /usr/bin/kvm-spice binary while...

... from the error message it looks like you're using the
/usr/bin/qemu-system-x86_64 binary instead, which does *not* contain
that machine type.

Since the newest machine type for that binary is versioned with 3.0,
are you sure you've compiled and installed QEMU 4.0?
