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
