As discussed in this old and still open bug#24496 [1], you could do
something like that for ’/etc/guix/machines.scm’:
--8<---------------cut here---------------start------------->8---
(define the-machine (build-machine …))
(if (managed-to-connect-timely the-machine)
(list the-machine)
'())
--8<---------------cut here---------------end--------------->8---
where ’managed-to-connect-timely’ could be a plain ’system*’ call via
’ping’ to the target offload machine. Guile probably provides a better
interface for network check. :-)
However, note that it could be nice to have something dynamically
handled [2] by the daemon. Feature missing…
