would prefer `guest-start-options`, as we have starts for other things (e.g., ceph or
systemd services)

The maximum value for timeout is 86400, the minimum 0, which disables the timeout completely. If timeout is unset, the timeout will either be the memory of the VM in GiBs or 30, depending on which is higher. If unset and hibernated, the value will at least be 300 seconds, with hugepages at least 150 seconds.",

please split to multiple lines with 100cc max each
