Getting Shutdown/Reboot to Work in KVM/QEMU

I was having trouble getting shutdown/reboot in virt-manager to work with KVM/QEMU. I had to do a Force Off, which is basically like pulling the plug. It's actually pretty easy to fix.



All I had to do for an Ubuntu Server guest was install the acpid daemon.

sudo apt-get install acpid

That's all. This was tested on Ubuntu Server 10.10 (Maverick Meerkat) & Ubuntu Server 11.10 (Oneiric Ocelot), but I'm guessing it would work for all other modern flavors of Ubuntu. If you have fixes for other guest OS's, please leave them in the comments.
