~ Welcome to Constellation! ~
Usually, on release versions of Constellation running in the cloud, you are not able to login through the serial console.
This shell access is specifically granted for debug images and MiniConstellation to allow users to research the environment Constellation runs in.
Have fun! Feel free to report any issues to GitHub or security@edgeless.systems (for security vulnerabilities only).
