Did you pass --image-size?  If not, it could be that the image size
estimate is slightly too small (see commit
a8ac4f081a9a679498ea42ccfe001f218bba3043).

The build log should contain something like:

  creating ~a image of ~,2f MiB...

where ~a is “raw” or “qcow2” depending on the “guix system” command you
used.

Could you check what happens if you pass a --image-size argument bigger
than that?

Thanks,
Ludo’.
