It took me a long time to work out why it happens. It turns out that it's because qemu uses 10.0.2.15 as a default address while installing, and that happens to reverse to some random machine on Red Hat's network. When guests install they try to self-determine their hostname from their IP address, so this happens. There's no a great deal I can do about this, but you can set your own hostname using the --hostname option.
