Re: [libvirt] [PATCH 1/2] conf: Disallow nonexistent NUMA nodes for hugepages

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/>?
