After 'mdevctl' was ran, its stdout is captured in @output which is then compared against NULL and if it is NULL a negative value is returned (to indicate error to the caller). But this is effectively a dead code, because virCommand (specifically virCommandProcessIO()) makes sure both stdout and stderr buffers are properly '\0' terminated. Therefore, this can never evaluate to true. Also, if there really is no output from 'mdevctl' (which was handled in one of earlier commits, but let just assume it wasn't), then we should not error out and treat such scenario as 'no mdevs defined/active'.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
