smolvm integrates with k8s (https://smolmachines.com/docs/guides/kubernetes-in-a-microvm...) and can mount s3 buckets (https://smolmachines.com/docs/local/machine-lifecycle-cli-re...).

I wouldn’t dismiss smolvm so fast. It brings together many ideas that make the whole very interesting.

It doesn’t provide isolation. It is not even part of the conversation.
