> So HVM guests without PV drivers can now be shutdown using ACPI.. > Is there 'xm' command for this aswell? Well, they'll do whatever the guest is internally configured to do when the power button is pressed e.g. nothing/shutdown/sleep/hibernate/crash It is possible to send an ACPI "fatal" event that will likely result in the system shutting down. However, the shutdown certainly isn't as graceful as a user initiated one -- I know windows doesn't prompt you to save files or close programs; I don't know if it even notifies user space applications. We could add ACPI support for 'Fatal' events, though someone would need to volunteer to do some more testing to understand the effects on different OSes.
