Unfortunately the feature has no UI yet, so I tested just db content and REST API calls: 1) Two NUMA hosts added to 3.5 cluster with shared NFS storage using webadmin 2) Database: a) Both hosts have is_numa_supported=true, auto_numa_balancing=1 in vds_dynamic table b) Both hosts have 2 records in numa_nodes tables (consistent with numactl info) c) Both hosts have 24 records in numa_node_cpu_map, 12 per numa node (consistent with numactl info) 3) REST API: a) URL /ovirt-engine/api/hosts/{HOST_ID} contains numa related data: <auto_numa_status>enable</auto_numa_status> <numa_supported>true</numa_supported> b) URL /ovirt-engine/api/hosts/{HOST_ID}/numanodes works (consistent with numactl info) c) URL /ovirt-engine/api/hosts/{HOST_ID}/numanodes/{NODE_ID}/statistics works 4) Installed two VMs (one RHEL 6, one RHEL 7), both requires 16GB of RAM, with balloon enabled and 8GB guarantied. 5) Database: a) Both vms have numatune_mode=preferred in vm_static 6) REST API for VM related data: a) URL /ovirt-engine/api/vms/{VM_ID} contains numa related data: <numa_tune_mode>preferred</numa_tune_mode> b) URL /ovirt-engine/api/vms/{VM_ID}/numanodes works, but returns only: <vm_numa_nodes/>

6) VMs migration between hosts worked fine
