I'd say no, at least until the default confinement of a guest to a single
node gets fixed to properly deal with guests having more vCPU-s than
a node's worth of pCPU-s (i.e. I take it for granted that the benefits of
not overcommitting CPUs outweigh the drawbacks of cross-node memory
accesses at the very least for CPU-bound workloads).
