When there is no vIOMMU, vfio devices don't need to lock the entire guest memory per-device, but they still need to lock the entire guest memory to share between all vfio devices. This memory accounting is not shared with vDPA devices, so it should be added to the memlock limit separately. Commit 8d5704e2 added support for multiple vfio/vdpa devices but calculated the limits incorrectly when there were both vdpa and vfio devices and no vIOMMU. In this case, the memory lock limit was not increased separately for the vfio devices.

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.
