Currently satprep_prepare_maintenance.py schedules downtimes before creating snapshots. When preparing maintenance for large system landscapes this means that the default downtime timeframe of 2 hours might already be exceeded after creating snapshots (because libvirt isn't able to create snapshots asynchronous).
So changing the order and increasing the downtime timeframe should do the trick.
