Machine type 'fedora-13' is a Fedora-specific alias for machine type
'pc-0.13' - that is, Fedora 13 was using qemu 0.12 but backported a
patch that added some machine features from qemu 0.13, so it invented
the name 'fedora-13' to expose those differences in default
capabilities.  It is a deprecated machine type (see bug
https://bugzilla.redhat.com/show_bug.cgi?id=754772), and there are plans
to silently convert 'fedora-13' into 'pc-0.13' prior to Fedora 18.

It has nothing to do with whether the guest or the host is running
Fedora 13 or any other version (although it will only appear in qemu
running on a fedora host).
