I'm a bit confused: our infrastructure uses libvirt/KVM, and "virsh
shutdown" works nicely. Back in the pre-systemd days, we had to
install acpid in the VMs to enable this functionality, and now
systemd-logind handles it by default in the KVM guests.

So I wonder: what's special about our Vagrant build VM, that prevents
this feature from working without qemu-guest-agent?
