Did you copy the XML file from the 5.7 host to 6.3 host as-is or did you edit it at all during the migration? I've found that I need either to run "virsh define $DOM.xml" and then start the new domain or run "virsh create $DOM.xml" and then, once it's running, make a trivial change (usually adding an XML comment) to the configuration via "virsh edit $DOM" to get things to stick. -- Paul Heinlein <> heinlein at madboa.com <> http://www.madboa.com/
