Fedora: Switch to upstream images

I don't know what strange memory defaults those images have, but the VM
goes OOM when we run the get_facts.sh script, so I adjusted the memory
to 2G. also rsync is used and no shared folder. So I disabled the
automatic shutdown so we can copy the files out of the VM.
