I think the problem was specify the number for QXL which never honored this setting. I don't think you can't migrate, just after migration the machine won't allow more than 1 head. Unfortunately the XML file does not have any field to specify the libvirt version was meant for. It would be useful to add so if you see the version it means that heads==1 means 1 if not it means is not defined. I'm against a new parameter which specify the same meaning of another parameter. I would instead something like validHeads or headsSet with a false as default. > >Christophe > Frediano _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
