berrange commented on the pull-request: `Permit an installation of only core storage drivers.` that you are following:
``
THis isn't really required. If someone wants to have a fully minimal install of QEMU/KVM, then install 'libvirt-daemon-driver-qemu', instead of 'libvirt-daemon-kvm' - the latter is the convenience intended to be fully featured.

We've tried to describe the intended usage here https://libvirt.org/kbase/rpm-deployment.html#deployment-choices

At least gnome-boxes and the Virtualization group in comps.xml will pull in libvirt-daemon-kvm.  And installing libvirt-daemon-driver-qemu instead will give users an installation without even libvirt-daemon-driver-storage-core, which seems... not great.
