 # Command to run the script when the container starts
-# The script needs to be run with the necessary privileges to access /sys and dmesg.
-# When running the container, the user will need to use '--privileged' or
-# map the necessary devices/directories, but for a simple check, we'll
-# rely on the host's environment when the container is run with the right flags.
-# For the purpose of this Dockerfile, we just set the entrypoint.
-ENTRYPOINT ["/app/detect_hypervisor.sh"]
+# The script relies on reading system files, so the container will still need
+# to be run with the necessary volume mounts.
+ENTRYPOINT ["python", "detect_hypervisor.py"]
 
-# Note: The script relies on reading system files like /sys/hypervisor/microsoft
-# and the output of 'dmesg'. To make this work inside a Docker container,
-# the container must be run with specific flags, typically:
-# docker run --rm -v /sys:/sys:ro -v /dev/kmsg:/dev/kmsg:ro --privileged <image_name>
-# I will include these instructions in the final delivery.
+# Note: The instructions for running the container will be updated to reflect
+# the need to mount the /sys filesystem for accurate detection.
