 If you have qemu installed (or in the SDK), you can start the image with:
   cd path/to/image

+  ./$(basename "${script}") -curses
 
 If you need to use a different ssh key or different ssh port:
-  ./$(basename "${script}") -a ~/.ssh/authorized_keys -p 2223 -- -curses ${arm64_msg}
+  ./$(basename "${script}") -a ~/.ssh/authorized_keys -p 2223 -- -curses
 
 If you rather you can use the -nographic option instad of -curses. In this
 mode you can switch from the vm to the qemu monitor console with: Ctrl-a c
