Xcluster is not tested on Fedora so there are likely some problems but here is a start anyway.
To run xcluster on Fedora 29 you must use a version >v1.0 or use
xcluster from the
master-branch.
sudo dnf install -y qemu-kvm qemu-img
sudo usermod -aG qemu $USER
# (logout/in to enable the new group)
sudo dnf install -y xterm jq genisoimage pxz screen
# (probably not needed;)
#sudo dnf install -y xorg-x11-xauth bitstream-vera-sans-mono-fonts
The kvm command differs from Ubuntu so you must specify it;
export __kvm=qemu-kvm
cd $HOME/xcluster
. ./Envsettings.k8s
