On: My VM is lighter (and safer) than your container (...

[1MachineElf]

While a flawed comparison, WSL does use a VM in conjunction with the 9p protocol to achieve folder sharing.

9p-based folder sharing is (used to be?) possible with qemu, too.

It looks like it still is supported [1]. I noticed while reading the Lima documentation that they're planning on switching from SSHFS to 9P [2].

Yep, can confirm.

NixOS configurations can be built and run as a qemu VM.

I very recently was using one and found they automatically make a 9p mount to /tmp.
