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.
