Greetings, I solved the problem. The solution is embarrassing; Qemu and KVM were not installed. I assumed (wrongly) that by installing the 'libvirt-bin' package, the other packages would install as dependencies but I was wrong. What mislead me is that many directories with 'qemu' in their names are created when installing 'libvirt-bin', such as '/etc/libvirt/qemu', giving the false impression that everything is there. It is by using the GUI (virt-manager) instead of the CLI (virsh) that I got an error stating that Qemu was not installed.
If any libvirt developer is reading this, a better error message would be appreciated. Something like "No virtual manager installed. Please install one such as Qemu." would be appreciated. I send my Thanks to Jakob Bohm and Ziemowit Pierzycki for answering my original email.
