spectrum-vm is a handy way to start a crosvm instance for testing crosvm itself, the kernel, or the rootfs. This commit adds some fledgling documentation on its functionality and usage. --- Takes into account review suggestions and tweaks a bit of wording here and there.
Specifically, I clarified that rootfs means the root filesystem, added an aside that the serial console can be used to run privileged commands, dropped the full `spectrum-vm --help` text, and moved and reformatted the usage examples.
Pushed, with a couple of minor tweaks. I put two spaces between each sentence for consistency with the rest of the file, and...
+Once you are ready to end your crosvm session, switch back to where you +ran `spectrum-vm` and type `reboot` (not `poweroff`). This window is not +limited to just stopping the VM, however; it is a functional serial +console where you can even run commands like `env` and `cat +/etc/passwd`.
I removed this "even" ^^^^ To ssh://atuin/home/spectrum/git/doc.git + fb12866...13e7dab master -> master Thanks so much! I'll take this off todo.html.
