Comment 10 for bug 994225

@Harald,

When you create guests you can specify the machine type, so if you're not tied to any features of a particular version number (the version numbers *are* supposed to provide a stable unchanging set of features, ideally :) you can certainly use 'pc'.

The script libvirt-migrate-qemu-machinetype is provided in quantal (and being SRUd to precise) to do the xml upgrading. That won't be done automatically, since not all users will want that, but you can run it yourself.
