Anywho, I was disabling services we don't need nor will use. I ran across "xen shutdown service". I figured it had something to do with the shutdown buttons in the cp. Is that what it does? I left it enabled since I have never seen it before, it also doesn't have a description so I figured it was something to do with the cp.. lol
Yes, that service is included with the Xen GPLPV drivers and allows the server to be shut down gracefully when we request it (such as through the button in the control panel, or when we need to reboot the machine for scheduled maintenance). I highly recommend leaving it running.
