Today, I created a KVM vm with windows 2016 server operation system by libvirt, and its memory can be hotplug with "virsh attachdevice" command, but vcpu cannot be hot-add with "virsh setvcpus". However, it is worked in windows 2008R2 and windows 2012R2 virtual machine, dose windows 2016 server support hot add cpu?

The command "virsh setvcpus" was worked, and there is no error in libvirt/qemu log, but it not works in vm, only reboot the vm that cpu will be added.
