After installing Sovereign Stack on your management machine, you need to enter the Sovereign Stack Management Environment (SSME). The SSME is a VM running on your management machine. It has all the software needed to manage one or more remote cluster hosts.
To enter the SSME, run ss-manage on your bare-metal management machine. This command SSHs into the ss-mgmt VM over a logical bridge network (incusbr0) created during install.sh.
