You need to run ssh-genkey once for each key that you want to use.
Typically once on each machine from which you will be originating
outbound connections.

Sometimes you want a separate keys for various purposes so you run it
multiple times on the same machine, but (hopefully obviously)
specifying different file names.

That's what ssh-copy-id does (more or less), especially if used with
the -i option to specify a single identity.
