This is neat! I’m assuming that this is Firecracker (or some other microVM hypervisor) underneath the hood?

If not (and you’re just raw-dogging Linux network/pid namespaces), I can see how you’ll struggle with persistence. The snapshots are larger with microVMs, but with userfaultfd, you’re able to lazily load pages back into memory as they’re accessed. Happy to chat more, my whole day job is making microVMs persistent :)

Thanks, I’ll send you an email!
