Since the end goal is the same (the guest is shut off either way), it is a good idea to write your scripts to be robust to this particular race. That said, if your guest isn't specifically requesting a shutdown, it seems odd that you are encountering a race, so there may be something else at play here. Does the log of the guest give any particular hints? -- Eric Blake eblake@xxxxxxxxxx +1-919-301-3266 Libvirt virtualization library http://libvirt.org
