That file is only written when we fail to migrate so it wouldn't
really be equivalent to a symlink. I'm not sure adding a symlink is a
good idea really though. We haven't done that for any other type of
migration and it would be a bit misleading here because the config
directory isn't really an exact match for ~/llibvirt and it may
actually cause a problem when an older version is used after
migration.

Perhaps that file isn't necessary if we exit on migration failures though.

Sending an updated patch.

Thanks,
Jon
