AffinityOrAntiAffinityGroup

association

VduBelongsTo

The affinity or anti-affinity group(s) the VDU belongs to. Each identifier references an affinity or anti-affinity group which expresses affinity or anti-affinity relationships between the virtualisation container(s) (e.g. virtual machine(s)) to be created using this VDU and the virtualisation container(s) (e.g. virtual machine(s)) to be created using other VDU(s) in the same group

LocalAffinityOrAntiAffinityRule

Specifies affinity or anti-affinity rules applicable between the virtualisation containers (e.g. virtual machines) to be created based on this VDU.

When the cardinality is greater than 1, both affinity rule(s) and anti-affinity rule(s) with different scopes (e.g. "Affinity with the scope resource zone and anti-affinity with the scope NFVI node") are applicable to the virtualisation containers (e.g. virtual machines) to be created based on this VDU.
