v86 VS webvm

> As a thought experiment, we're almost there! We could technically have `win95.img + bochs86vm.wasm + autorun.inf + msword.exe` wrapped in a "browser evaluator"

I looked into this and... holy crap! We are there. Not for modern programs quite yet, sure, but this is amazing. You can use Windows 2000 from your browser.

I think you are looking for Shadow.

Or just the whole kitchen sink. Why not?

Also: https://github.com/copy/v86 - more productized browser x86 runtime, used by eg https://github.com/snaplet/postgres-wasm

Wonder if you could put all those databases in a Linux image and boot it using v86 [0], eliminating the need for a server.

Trying it out in https://copy.sh/v86/?profile=kolibrios , it's also clearly a love letter to Windows 95 in particular. That could be an unstated goal here, create a very particular PC experience under very particular constraints. I don't know anything about the creator but it's very possible that this kind of work was actually their career in the 90s.

It's incredible how much work was done. Maybe this should be an internet curiosity like how TempleOS has become, though Terry's personality was a unique factor.

hmm, why would people still use VMWare? Isn't vbox open source, or even things such as https://copy.sh/v86/ would do most virtualization trick now days?

Oh, there are more OSes one can use at the parent page:

My highlights:

- First version of Windows (1.01)

- SerenityOS <3

- and even ReactOS

Shameless self-promotion: https://webvm.io

Powered by a x86->Wasm JIT. Technical writeup: https://labs.leaningtech.com/blog/webvm-server-less-x86-virt...

Developer here. CheerpX for Flash runs the Pepper API version of Flash, and you're correct about the license. However, we don't do full Linux emulation just to run Flash - we emulate PPAPI and run the Flash player in an x86 JIT (CheerpX).

Yuri talks about CXFF's architecture here:

...but if you wanted full Linux system emulation, we got it! https://webvm.io

webvm has Tailscale sockets-over-WebSockets for networking: https://github.com/leaningtech/webvm

https://webvm.io/ supports WebVM runs x86 binaries in WASM on any browser w/ ("CheerpX includes an x86-to-WebAssembly JIT compiler, a virtual block-based file system, and a Linux syscall emulator") and for external sockets there's Tailscale networking.

IIUC that means an SSH client in a WebVM can connect to a (tailscale (wg)) VPN mesh

lets pre-load it into a https://github.com/leaningtech/webvm/blob/main/dockerfiles/debian_mini

Just to show how complex these can get look at this https://webvm.io/

Funnily enough, I believe that's completely achievable with enough time spent on it (probably a few weeks of an engineer working full time).

We have technology like WebVM [1] (from leaningtech / CheerP) or Copy86 [2] that already allows x86 machine code execution/emulation on the web. If you add an OCI client layer on top that is executable in the browser, it should be possible to run Docker containers in the browser.
