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.
