mdevctl can report multiple defined devices with the same UUID but different parents, including parents that don't actually exist on the host machine. Libvirt sets the parent to the 'computer' device for all of the mdevs that have nonexistent parents. Because of this, it's possible that there are multiple devices with the same UUID and the same 'computer' device as their parent, so the combination of uuid and parent nodedev name is not guaranteed to be a unique name. We need to ensure that each nodedev has a unique name. If we can't use the UUID as a unique nodedev name, and we can't use the combination of UUID and nodedev parent name, we need to find another solution. By caching and using the parent name reported by mdevctl in combination with the UUID, we can achieve a unique name. mdevctl guarantees that its uuid/parent combination is unique. This value will be used to set the mdev nodedev name in a following commit. Signed-off-by: Jonathon Jongsma <jjongsma@redhat.com> Reviewed-by: Michal Privoznik <mprivozn@redhat.com> |

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.
