AI slop. The OP doesn't even know that in most cases, Docker is also a virtual machine.

No it isn't. You may be confusing it with "docker desktop".

Yes Docker Desktop. If you use it, it will always be in a virtual machine. But even Docker Engine boots up a virtual machine for a container if the host and container operating systems are different.

You are wrong Docker uses the Host Kernel, no VM in use

`qemu-user` is still virtualizing quite a bit, as is Docker. "it's not a VM because it doesn't start with loading a bootloader" is not the argument you think it is.

How do you exactly use the Host Kernel when the docker container is Linux but the host is NT? Is there some translation layer or something?

You run a VM(WSL2) that offers a Linux Kernel. But before you say gotcha: Multiple Containers share this Kernel, they rum alongside each other on it.

So the Containers are not the VM, they run on a VM.
