@dabeazDavid Beazley I don't get why people don't want to do CS research. This is from ACM Communications on Docker.

As a workaround, we turned to the unikernel libraries from MirageOS21 to translate between Linux networking requests and macOS and Windows native socket calls. When a container attempts a TCP handshake, an ethernet frame containing the TCP SYN is sent to the host over the virtio protocol33 using shared memory on the Mac (Figure 5). This is then received by the “library VMM” and sent by sendmsg into the userspace TCP/IP stack running on the host OS. This userspace stack, dubbed vpnkit and written in OCaml,23 then invokes the macOS connect() syscall and either completes the TCP handshake or signals an error. With this architecture, the outgoing traffic from the Linux container will be perceived by the VPN policy as originating from the Docker application rather than from a separate machine. Deploying vpnkit in our beta tests in 2016 reduced bug reports from corporate users by more than 99%, and this approach has been a key component of Docker for Mac and Windows ever since. The SLIRP approach has subsequently seen adoption elsewhere in the serverless cloud world,40 reviving an old dial-up networking trick to solve new problems in container management.
