The nova.objects.instance_numa_topology Module

class InstanceNUMACell(**kwargs)

Bases: nova.objects.base.NovaObject, nova.objects.base.NovaObjectDictCompat

VERSION = '1.3'

clear_host_pinning()

Clear any data related to how this cell is pinned to the host.

Needed for aborting claims as we do not want to keep stale data around.

cpu_pinning

Descriptor allowing us to assign pinning data as a dict of key_types

This allows us to have an object field that will be a dict of key_type keys, allowing that will convert back to string-keyed dict.

This will take care of the conversion while the dict field will make sure that we store the raw json-serializable data on the object.

key_type should return a type that unambiguously responds to six.text_type so that calling key_type on it yields the same thing.
