 By default, qemu-system-x86_64 is searched in $PATH to run the guest. If there
 isn't one, or if it is older than 2.10, the test won't work. In this case,
 provide the QEMU binary in env var: ``QEMU=/path/to/qemu-2.10+``.
 
+Likewise the path to qemu-img can be set in QEMU_IMG environment variable.
