The guest table marks with "!" each guest that Proxmox's not-backed-up list returns. The frame's bottom border shows the count, e.g. "mainframe · 2 without backup job". This uses Proxmox's own answer, so it also counts jobs that select guests by pool. If the coverage call fails, the guests are still listed and a warning says the coverage is unknown.
