I had the same issue and posted about it here: [Elasticseach 9.4.0 Won't Start on Nehalem CPU "does not support all the following CPU features"](https://discuss.elastic.co/t/elasticseach-9-4-0-wont-start-on-nehalem-cpu-does-not-support-all-the-following-cpu-features/386216)

There is a pull request to fix the issue: [Pin server-launcher native -march to x86-64-v2 by JVerwolf · Pull Request #148542 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/pull/148542)
