[ovirt-devel] oVirt 3.5 test day 2 results - NUMA

[Martin Perina]

Hi,

I tried to test NUMA feature. 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
