# Browser VM
|
||||||
A small Linux x86 VM meant for use in the browser
|
|
||||||
|
A custom [Buildroot](https://buildroot.org/) config for a Linux x86 VM, meant to
|
||||||
|
be run in the browser. The resulting Linux ISO is meant to be run under
|
||||||
|
emulation in the browser via [v86](https://github.com/copy/v86), and includes:
|
||||||
|
|
||||||
|
* a custom Linux 4.15 kernel, which strips out many unnecessary drivers, modules, etc. and adds [Plan 9 filesystem](https://www.kernel.org/doc/Documentation/filesystems/9p.txt) sharing
|
||||||
|
* a root filesystem and Unix commands via [BusyBox](https://busybox.net/)
|
||||||
|
* an ISO-based bootloader (i.e., we create a "DVD" that is booted by v86)
|
||||||
|
|
||||||
|
Following the [Buildroot customization docs](https://buildroot.org/downloads/manual/manual.html#customize)
|
||||||
|
we create a folder `buildroot-v86/` with all the necessary config files,
|
||||||
|
filesystem overlay, and scripts necessary to build our distribution.
|
||||||
|
|
||||||
|
## Running via Docker
|
||||||
|
|
||||||
|
To build the Docker image:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ docker build -t buildroot .
|
||||||
|
```
|
||||||
|
|
||||||
|
And then to run the build:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ docker run \
|
||||||
|
--rm \
|
||||||
|
--name build-v86 \
|
||||||
|
-v $PWD/dist:/build \
|
||||||
|
-v $PWD/buildroot-v86/:/buildroot-v86 \
|
||||||
|
buildroot
|
||||||
|
```
|
||||||
|
|
||||||
|
NOTE: we define two [volumes](https://docs.docker.com/engine/reference/builder/#volume) to
|
||||||
|
allow the container to access the v86 config, and also to write the ISO once complete. In the
|
||||||
|
above I've used `$PWD`, but you can use any absolute path.
|
||||||
|
|
||||||
|
When the build completes, an ISO file will be places in `./dist/v86-linux.iso`
|
||||||
|
in your source tree (i.e., outside the container).
|
||||||
|
|
||||||
|
If you need to re-configure things, instead of just running the build, do the following:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ docker run \
|
||||||
|
--rm \
|
||||||
|
--name build-v86 \
|
||||||
|
-v $PWD/dist:/build \
|
||||||
|
-v $PWD/buildroot-v86/:/buildroot-v86 \
|
||||||
|
-ti \
|
||||||
|
--entrypoint "bash" \
|
||||||
|
buildroot
|
||||||
|
```
|
||||||
|
|
||||||
|
Now in the resulting bash terminal, you can run `make menuconfig` and [other make commands](https://buildroot.org/downloads/manual/manual.html#make-tips).
|
||||||
|
|
||||||
|
## `buildroot-v86/` Layout
|
||||||
|
|
||||||
|
We define a `v86` buildroot "board" via the following files and directories:
|
||||||
|
|
||||||
|
```
|
||||||
|
+-- board/
|
||||||
|
+-- v86
|
||||||
|
+-- linux.config # our custom Linux kernel config (make linux-menuconfig)
|
||||||
|
+-- post_build.sh # script to copy ISO file out of docker container
|
||||||
|
+-- rootfs_overlay/ # overrides for files in the root filesystem
|
||||||
|
+-- etc/
|
||||||
|
+-- inittab # we setup a ttyS0 console terminal to auto-login
|
||||||
|
+-- fstab # we auto-mount the Plan 9 Filer filesystem to /mnt
|
||||||
|
+-- configs/
|
||||||
|
+-- v86_defconfig # our custom buildroot config (make menuconfig)
|
||||||
|
+-- Config.in # empty, but required https://buildroot.org/downloads/manual/manual.html#outside-br-custom
|
||||||
|
+-- external.mk # empty, but required https://buildroot.org/downloads/manual/manual.html#outside-br-custom
|
||||||
|
+-- external.desc # our v86 board config for make
|
||||||
|
+-- build-v86.sh # entrypoint for Docker to run our build
|
||||||
|
```
|
||||||
|
|
||||||
|
If you need or want to update these config files, do the following:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ make BR2_EXTERNAL=/buildroot-v86 v86_defconfig
|
||||||
|
$ make menuconfig
|
||||||
|
...
|
||||||
|
$ make savedefconfig
|
||||||
|
$ make linux-menuconfig
|
||||||
|
...
|
||||||
|
$ make linux-savedefconfig
|
||||||
|
```
|
||||||
|
|
||||||
|
## Configuration Notes
|
||||||
|
|
||||||
|
These are the options I set when configuring buildroot for v86. I'm only
|
||||||
|
specifying the things I set.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ cd buildroot-2018.02
|
||||||
|
$ make menucofing
|
||||||
|
```
|
||||||
|
|
||||||
|
Then follow these config steps in the buildroot config menu (NOTE: these docs
|
||||||
|
may have drifted from the actual config in the source, so consult that first):
|
||||||
|
|
||||||
|
### Target options
|
||||||
|
|
||||||
|
* Target Architecture: i386
|
||||||
|
* Target Architecture Variant: pentium mobile (Pentium with MMX, SSE)
|
||||||
|
|
||||||
|
### Build options
|
||||||
|
|
||||||
|
* Enable compiler cache (not strictly necessary, but helps with rebuilds)
|
||||||
|
|
||||||
|
### Toolchain
|
||||||
|
|
||||||
|
* C library: uLibc-ng (I'd like to experiment with musl too)
|
||||||
|
|
||||||
|
### System configuration
|
||||||
|
|
||||||
|
* remount root filesystem read-write during boot (I think this is unnecessary)
|
||||||
|
* Root filesystem overlay directories: /build/overlay-fs (for etc/inittab)
|
||||||
|
|
||||||
|
### Kernel
|
||||||
|
|
||||||
|
* Linux Kernel: true
|
||||||
|
* Defconfig name: i386
|
||||||
|
* Kernel binary format: bzImage (vmlinux seemed to break on boot)
|
||||||
|
|
||||||
|
### Target packages
|
||||||
|
|
||||||
|
Need to figure this out. I tried adding imagemagik, git, uemacs, but they
|
||||||
|
are all adding too much size to the image.
|
||||||
|
|
||||||
|
### Filesystem images
|
||||||
|
|
||||||
|
* cpio the root filesystem (for use as an initial RAM filesystem)
|
||||||
|
* initial RAM filesystem linked into the linux kernel (not sure I need this, trying without...)
|
||||||
|
* iso image
|
||||||
|
* Use initrd
|
||||||
|
* tar the root filesystem Compression method (no compression)
|
||||||
|
|
||||||
|
### Bootloaders
|
||||||
|
|
||||||
|
* syslinux
|
||||||
|
* install isolinux
|
||||||
|
|
||||||
|
## Linux configuration
|
||||||
|
|
||||||
|
Now configure the Linux Kernel:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ make linux-menuconfig
|
||||||
|
```
|
||||||
|
|
||||||
|
And set the following options to accomplish this:
|
||||||
|
|
||||||
|
```
|
||||||
|
CONFIG_NET_9P=y
|
||||||
|
CONFIG_NET_9P_VIRTIO=y
|
||||||
|
CONFIG_9P_FS=y
|
||||||

|
||||||
|
CONFIG_VIRTIO_PCI=y
|
||||||
|
CONFIG_PCI=y
|
||||||
|
CONFIG_VIRTIO_PCI=y
|
||||||
|
```
|
||||||
|
|
||||||
|
# Processor type and features
|
||||||
|
|
||||||
|
* Processor family (Pentium-Pro) also tried Pentium M before.
|
||||||
|
|
||||||
|
# Bus options (PCI, etc.)
|
||||||
|
|
||||||
|
* PCI Debugging: true (I want to see what's happening with PCI errors, normally not needed)
|
||||||
|
|
||||||
|
# Networking support
|
||||||
|
|
||||||
|
* Plan 9 Resource Sharing Support (9P2000) (built into kernel * vs. M)
|
||||||
|
* 9P Virtio Transport (* - make this is on, it won't exist if virtio is off)
|
||||||
|
* Debug information (* - optional)
|
||||||
|
|
||||||
|
# Device Drivers
|
||||||
|
|
||||||
|
* Virtio drivers
|
||||||
|
* PCI driver for virtio devices (built into kernel * vs. M)
|
||||||
|
* Support for legacy virtio draft 0.9.X and older devices (New)
|
||||||
|
* Platform bus driver for memory mapped virtio devices (* vs. M) - not sure I need this...
|
||||||
|
* Memory mapped virtio devices parameter parsing - or this...
|
||||||
|
|
||||||
|
# Filesystems
|
||||||
|
|
||||||
|
* Caches
|
||||||
|
* General filesystem local caching manager (*)
|
||||||
|
* Filesystem caching on files (*)
|
||||||
|
|
||||||
|
* Network File Systems
|
||||||
|
* Plan 9 Resource Sharing Support (9P2000) (*)
|
||||||
|
* Enable 9P client caching support
|
||||||
|
* 9P Posic Access Control Lists
|
||||||
|
|
||||||
|
Now run `make`
|
||||||
|
|
||||||
|
When it finishes, the built image is in `./output/images`.
