on my Cloudmin GPL server is Ubuntu VM. As backup app is using Bacula, which is set to shutdown Ubuntu VM by cloudmin shutdown command (cloudmin shutdown-system --host ubuntu.domain.local).
Cloudmin has full access to VM (SSH, webmin), but all shutdown by this command is forced. No nice shutdown by SSH, webmin or ACPI.
I tested to send ACPI shutdown in qemu monitor (system_powerdown) and it's working as nice properly shutdown.
Please, can anybody explain me how shutdown command works?
