[virt-tools-list] Why virsh shutdown does not work?

[Decker, Schorschi]

That is a major no-go from a security perspective, enabling that feature.

Are you having this problem on Windows or Linux VMs?  I don't have this issue with Linux VMs (provided I installed them with the virtio drivers).  However, on a Windows VM there is an extra step that I do to make it work:

Start>Run: gpedit.msc

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