In the future, either paste just the text from your screen rather than a screenshot, or upload the image somewhere else and post only the URL to your upload, so that the list isn't spammed with a huge image attachment. [And speaking as a list moderator, my apologies to other list readers for moderating this one through; often, I'm able to catch large message attachments and reject the posts with suggestions for a smaller message, without the list having to see the original large message] -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
