I wanted to play a bit with Fedora Rawhide so I installed Fedora 23 to a VM. I named it Blargg after the Fire Dragon in Super Mario World. (See video below) I used the following commands from the Fedora wiki:
# dnf upgrade dnf # dnf install dnf-plugins-core fedora-repos-rawhide # dnf config-manager --set-disabled fedora updates updates-testing # dnf config-manager --set-enabled rawhide # dnf clean -q dbcache plugins metadata # dnf --releasever=rawhide --setopt=deltarpm=false distro-sync --nogpgcheck ## Optional: it is generally advised to do a selinux autorelabel and reboot # touch /.autorelabel
