As of 136ad4974 it is possible to specify different huge pages per
guest NUMA node. However, there's no check if nodeset specified in
./hugepages/page contains only those guest NUMA nodes that exist.
In other words with current code it is possible to define meaningless
combination:
<memoryBacking>
<hugepages>
<page size='1048576' unit='KiB' nodeset='0,2-3'/>
<page size='2048' unit='KiB' nodeset='1,4'/>
</hugepages>
</memoryBacking>
<vcpu placement='static'>4</vcpu>
<cpu>
<numa>
<cell id='0' cpus='0' memory='1048576'/>
<cell id='1' cpus='1' memory='1048576'/>
<cell id='2' cpus='2' memory='1048576'/>
<cell id='3' cpus='3' memory='1048576'/>
</numa>
</cpu>
Notice the node 4 in <hugepages/>?
