If there are no plans to support vcpu hotplug for pseries in xenial, my suggestion would be having the error statement while trying hotplug be improved saying hotplug is not supported with version of qemu/libvirt, or we can bring in all the necessary changes required for vcpu hotplug in xenial aswell. please advice.

There can a real possibility of having a memory less numa node as a valid config of system provided the system does not have full config(maximum memory possible for that system), which can cause these functional issues that can be resolved by having this fix. More over host numa node config affecting guest functional is unacceptable, so it is good to have this fix applied, Thanks.
