What sometimes happens is that you create a VM (lets say with virt-manager) on an old installation, and it has the XML file for that VM which I think includes the machine type. You upgrade your host or copy your VMs over and so you still use the old machine definition, and hence still have the -M pc-1.0 Some people have snapshots rather than just disk images taken with particular versions and they expect those to be reloadable into newer versions.
