Shutdown, is this an ACPI broadcast

OS type and version Ubuntu Linux 22.04.4
Webmin version 2.111
Usermin version 2.010
Virtualmin version 7.10.0
Theme version 21.10
Package updates All installed packages are up to date


  • When I use Webmin --> System --> Bootup and Shutdown --> Shutdown Does this send an ACPI broadcast to the server
  • Also does an ACPI broadcast cause a graceful shutdown of a server.

Why do I ask

I have my virtulmin running on a virtual machine on a TrueNAS PC, this has the option of shutting down all virtual servers using an ACPI broadcast and I want to know if it is safe.



You can check the module configuration to see which command is used for shutdown.
