Hello, We use a selfmade GUI environment which utilizes Xen to provide preinstalled OS images. The state of a specific vm is shown in the user's GUI and used by the web application. To decide whether or not a vm is running we call "/usr/sbin/xm list <vmid>". If the call is successful we know that the vm is running. If it fails, we know that there's no vm running ;-) So far so good... My question: what happens if a user triggers a reboot inside of the vm, e.g. by executing "reboot" in Linux. Are Xen vm images always running even if the user has rebooted the image or is it stopped for a short moment right before the OS image is restarted? And if it's stopped, is it possible to say how long it is approximately stopped and/or not listed by "xm list"? I have tried to google some information but weren't really successful and I don't know how to find out on my own if the vm is stopped while it is rebooted. Thanks in advance!
