Steps to reproduce:
1. Define a guest with below numa configuration( refer attachment for complete guest xml)
$sudo virsh define F27.xml

..
<vcpu placement='static' current='2'>8</vcpu>
..
 <cpu mode='host-model' check='partial'>
    <model fallback='allow'/>
    <topology sockets='1' cores='8' threads='1'/>
    <numa>
      <cell id='0' cpus='0-1' memory='0' unit='KiB'/>
      <cell id='1' cpus='2-3' memory='2097152' unit='KiB'/>
      <cell id='2' cpus='4-5' memory='0' unit='KiB'/>
      <cell id='3' cpus='6-7' memory='0' unit='KiB'/>
    </numa>
  </cpu>

2. Boot the guest and check vcpus inside guest
$sudo virsh start F27

3. hotplug vcpus from libvirt
$sudo virsh setvcpus F27 8 --live
