Show HN: Clone, a small Rust VMM, forks VMs in under 20ms via CoW We needed a secure, multi-tenant way to offer shell accounts to users, but most VMMs were using too much memory and containers are unsafe. With clone, VMs are now more memory efficient than containers in most cases.

Since many other projects on HN looked like they were doing this too, open sourcing this was the right thing to do.

Feel free to use in whole or in part as you see fit!
