With a centos 7 minimal machine, I've run the following commands:
yum update -y
yum install -y vim docker wget git net-tools bind-utils iptables-services bridge-utils bash-completion libvirt libvirt-daemon qemu-kvm libvirt-daemon-kvm qemu-img libvirt-python libvirt-client virt-install virt-viewer virt-manager

From googling, all I can find are recommendations to add my user to the libvirtd group, and install additional packages, and I think I've already incorporated all of those steps into my above script. What am I missing?
