@ -2,7 +2,24 @@ You can build a Linux image for use with v86:
1. Run `./build-container.sh` to build the Docker container and v86 images (requires dockerd)
2. Run `./build-state.js` to build a state image in order to skip the boot process
3. Optionally, compress the `debian-state-base.bin` file using zstd (v86 automatically detects the zstd magic and decompresses on the fly)
4. Run a webserver serving repo root and go to `examples/debian.html` in a browser
Go to `debug.html?profile=debian` to start the generated container.
If you want to see more info you can run it in a debug mode, to do so add a new profile in the `src/browser/main.js` file to the `oses` variable like so:
```js
var oses = [
{
id: "debian",
name: "Debian",
memory_size: 512 * 1024 * 1024,
vga_memory_size: 8 * 1024 * 1024,
state: { url: host + "debian-state-base.bin" },
filesystem: { "baseurl": host + "debian-9p-rootfs-flat/" }
},
...
```
Save it and go to `debug.html?profile=debian` to start the generated container.
You can modify the `Dockerfile` to customize the generated Linux image.
