I believe these test scripts which build/launch the VM have to support
the older version of QEMU since
this is the version of QEMU currently used when these VMs are
launched.  I don't know the history on
this, but it seems intentional that we use one older/different version
of QEMU to launch the VM,
while we test the 'current' build of QEMU inside the VM.
It also seems like a 'nice to have' to automatically support the
latest version where we could
use max as you pointed out.
