For a simple configuration where the VM fits within a host numa node, you'd want to add something like:<numatune> <memory mode="strict" nodeset="1"/> </numatune> Which should allocate all VM memory from numa node 1. Use the information in the sysfs paths above to verify that free hugepage count is going down on the intended node. If your VM spans NUMA nodes, things get a lot more complicated and you'll need to fiddle with memnodes here and nodesets in the <hugepages> setup.
Thank you for help here, with these two magic words numatune and nodeset I was able to find full explanation at http://www.admin-magazine.com/Archive/2014/20/Best-practices-for-KVM-on-NUMA-servers
