I don't think so.
~~~ The most common case will be that the admin only sets hw:numa_nodes and then the flavor vCPUs and memory will be divided equally across the NUMA nodes. When a NUMA policy is in effect, it is mandatory for the instance's memory allocations to come from the NUMA nodes to which it is bound except where overriden by hw:numa_mem.NN. ~~~
Here are the implementation documents since Juno release:

Is there any concern to enable 'hw:numa_nodes=1' on all flavors, as long as that flavor can fit into one numa node?
