This function handles the change of NUMA nodeset for a given guest, setting CpusetMems for the emulator, vcpus and IOThread sub-groups. It doesn't set the same nodeset to the root cgroup though. This means that cpuset.mems of the root cgroup ends up holding the new nodeset and the old nodeset as well. For a guest with placement=strict, nodeset='0', doing virsh numatune <vm> 0 8 --live Will make cpuset.mems of emulator, vcpus and iothread to be "8", but cpuset.mems of the root cgroup will be "0,8". This means that any new tasks that ends up landing in the root cgroup, aside from the emulator/vcpus/iothread sub-groups, will be split between the old nodeset and the new nodeset, which is not what we want.

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