Looks cool! In the short demo [0] they mention "within a few hundred milliseconds" as VM boot time (I assume?). I wonder how much tweaking they had to do, because this is using the Virtualization.framework, which has been around a while and used by Docker dekstop / Colima / UTM (as an option).

I wonder what the memory overhead is, especially if running multiple containers - as that would spin up multiple VM's.

They include the kernel config here[0]

> Containers achieve sub-second start times using an optimized Linux kernel configuration[0] and a minimal root filesystem with a lightweight init system.
