BTW if you need NUMA emulated in your KVM add the below to your virsh edit
<cpu>
....
<numa>
<cell cpus='0-3' memory='5242880'/>
<cell cpus='4-7' memory='3145728'/>
</numa>
</cpu>
memory= is in KiB only
The sum of these must exactly match what you have for
<memory unit='KiB'>8388608</memory>
<currentMemory unit='KiB'>8388608</currentMemory>
And you probably already have say:
<topology sockets='2' cores='4' threads='1'/>
Cheers
