Hi, I had already said the same as comment of the v1 patch,

I don't care personally, but all my customers coming from vmware, xcp-
ng, or cloud provider with ec2 or gcp, everybody in the industry is
using "affinity/antifinity host/vms" since 20years , and I'm pretty
sure that if they read the doc and some whitepaper/benchmark
comparaison  on the net (not even talking about chatgpt lol), they'll
think that the feature is not available.
