В логах службы ошибка: pve_exporter[1856]: pve_exporter: error: unrecognized arguments: /etc/prometheus/pve.yml

Изучил systemd-юнит, нашёл решение: 
Файл /etc/systemd/system/prometheus-pve-exporter.service.d/override.conf с содержимым:

[Service]
ExecStart=
ExecStart=/usr/bin/pve_exporter --config.file /etc/prometheus/pve.yml

После чего служба корректно работает без падения. Не хватает указания --config.file
