The GIF's prety much crystal clear: it runs QEMU on Linux. And QEMU runs whatever you want, because it's a machine emulator/virtualiser, in this case it's running as x86 with MS DOS on top.
- plus 6y agoNo.... QEMU is being used to run DOS, since a) who runs DOS on metal these days, and b) how would you record the screen if you were running DOS on metal (I suppose you could use a capture card). Linux is running in a WSL-like environment on the DOS host.

- hnlmorg 6y agoNo, qemu is only there to boot DOS. DOS then runs Linux commands via `dsl` (DOS Subsystem for Linux). You could perhaps argue "inception" since it's Linux running a DOS VM running Linux commands. But the charitable explanation is the author just wanted a convenient environment to do DOS development rather than bare metal (think of it like a Vagrant box).
- lights0123 6y agoNo, the interesting part is what's happening in DOS. QEMU was probably just used for screenshots and not going through the pain of installing DOS on a new machine.
- JdeBP 6y agoThis entire discussion is strong evidence that the GIF is not crystal clear at all. (-:
