HI Yaniv

I looked at your reference and it looks like I have almost the same thing,
but I was looking to take it a step further with virtual numa node. Is it
necessary to really do it for extra performance? Below is my code snippet,
it is not cleaned up yet, but works. I am also looking at programatically
added host devices such as a GPU. Do you have an example of doing that?

# Get the "vms" service
vms_service = connection.system_service().vms_service()

# Create vm
vms_service.add(
types.Vm(
name='test',
type=types.VmType('high_performance'),
memory=20 * 2**30,
memory_policy=types.MemoryPolicy(guaranteed=20 * 2**30,
ballooning=False, max=20 * 2**30),

os=types.OperatingSystem(boot=types.Boot(devices=[types.BootDevice.NETWORK,
types.BootDevice.HD]), type='LINUX'),
#time_zone=types.TimeZone('GMT-06:00'),
numa_tune_mode=types.NumaTuneMode('preferred'),
io=types.Io(threads=1),
cpu=types.Cpu(topology=types.CpuTopology(cores=1, sockets=4,
threads=1), mode=types.CpuMode('host_passthrough'),
 cpu_tune=types.CpuTune(vcpu_pins=[types.VcpuPin('24', 0),
types.VcpuPin('25', 1), types.VcpuPin('26', 2), types.VcpuPin('27', 3)])),


placement_policy=types.VmPlacementPolicy(affinity=types.VmAffinity('pinned'),
hosts=[types.Host(name='lab5')]),
custom_properties=[types.CustomProperty('hugepages', 'hugepages',
'1048576')],
cluster=types.Cluster(
name='lab5-Local',
),
template=types.Template(
name='Blank',
),
),
)

Thanks

Don

I am able to create a vm using the sdk with nic and disks using the python
sdk, but having trouble understanding how to assign it to virtual numanode
onto the physical numanode via python sdk. Any help in this area would be

Thanks Andrej. I will use this information and see how far I get.

Re: [ovirt-users] Ovirt 4.2 - Help adding VM to numa node via python SDK

Hi,

The VirtualNumaNode[1] object has 'numa_node_pins' member, that is a list
of NumaNodePin[2].
Most of the members of NumaNodePin object are deprecated and not used.
The important one is 'index', which is the index of the host numa node to
which the
vm numa node is pinned. Here is the REST API documentation: [3].

A simple python example can be:


import ovirtsdk4 as sdk

conn = sdk.Connection("URL", "admin@internal", "PASSWORD")

host_node = conn.service("hosts/123/numanodes/456").get()

vm_node_service = conn.service("vms/789/numanodes/123")
vm_node = vm_node_service.get()

vm_node.numa_node_pins = [ sdk.types.NumaNodePin(index=host_node.index,
pinned=True) ]

vm_node_service.put(vm_node)
