When starting a domain with <numatune/> set libvirt translates given NUMA nodes into a set of host CPUs which is then used to QEMU process affinity. But, if the numatune contains a non-existent NUMA node then the translation fails with no error reported. This is because virNumaNodesetToCPUset() calls virNumaGetNodeCPUs() and expects it to report an error on failure. Well, it does except for non-existent NUMA nodes. While this behaviour might look strange it is actually desired because of how we construct host capabilities. The virNumaGetNodeCPUs() is called from virCapabilitiesHostNUMAInitReal() where we do not want any error reported for non-existent NUMA nodes.

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.
Further information about the libvirt project can be found on the
website:
