Currently, we have three different types of mdevctl errors: 1. the command cannot be constructed ecause of unsatisfied preconditions 2. the command cannot be executed due to some error 3. the command is executed, but returns an error status These different failures are handled differently. Some cases set an error and return and error status, and some return a error message but do not set an error. This means that the caller has to check both whether the return value is negative and whether the errmsg parameter is non-NULL before deciding whether to report the error or not. The situation is further complicated by the fact that there are occasional instances where mdevctl exits with an error status but does not print an error message. This results in errmsg being an empty string "" (i.e. non-NULL). Simplify the situation by ensuring that virReportError() is called for all error conditions rather than returning an error message back to the calling function.

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.
