vCPU soft affinity and NUMA-aware scheduling does not have to be related. However, soft affinity is how NUMA-aware scheduling is actually implemented, and therefore, by default, the results of automatic NUMA placement (at VM creation time) are also used to set the soft affinity of all the vCPUs of the domain. Of course, this only happens if automatic NUMA placement is enabled and actually takes place (for instance, if the user does not specify any hard and soft affiniy in the xl config file). This also takes care of the vice-versa, i.e., don't trigger automatic placement if the config file specifies either an hard (the check for which was already there) or a soft (the check for which is introduced by this commit) affinity.
