QEMU

sudo dnf update
sudo dnf install qemu

From QEMU's source files

# Install prerequisite rpms to build the source code
sudo dnf install pixman-devel gcc make git

# Download source code
git clone git://git.qemu.org/qemu.git
cd qemu
mkdir build; cd build
../configure  --target-list='ppc64-softmmu ppc-softmmu'
make
make install
/usr/local/bin/qemu-system-ppc64 --version

If you don not mentioned the  --target-list='ppc64-softmmu ppc-softmmu', it will build more than 50 machines emulator, and will take a longer time to compile. fore more info, type #../configure -h
