QEMU/KVM ACPI Guest Shutdown

When using Fully Virtualized Machines (KVM) Proxmox will use ACPI to send clean shutdown signals to the Virtual Machines via the web gui and scripts. Your Virtual Machines need to support ACPI to be able to shut down clean.

For Linux Virtual Machines, make sure that the ACPI event daemon is installed and running. Desktop distributions should already have it, but minimal or Server distributions may not.

For Ubuntu and Debian, all versions, install the package acpid in the Virtual Machine.

For Windows, make sure an ACPI hal is installed.

On Windows server 2003/8 also make sure to change policy to allow shutdown without being logged into the system. Start->Run:

gpedit.msc

Find the following key:

Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Shutdown: Allow system to be shut down without having to log on

Change it to Enabled.
