In commit 68580a51, I removed the checks for NULL cmd variables because
virCommandRun() already handles the case where it is called with a NULL
cmd. Unfortunately, it handles this case by raising a generic error
which is both unhelpful and overwrites our existing error message. So
for example, when I attempt to create a mediated device with an invalid
parent, I get the following output:
virsh # nodedev-create mdev-test.xml
error: Failed to create node device from mdev-test.xml
error: internal error: invalid use of command API
With this patch, I now get a useful error message again:
virsh # nodedev-create mdev-test.xml
error: Failed to create node device from mdev-test.xml
error: internal error: unable to find parent device 'pci_0000_00_03_0'

==============================
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.
