Add an optional --vmtest-web flag that starts an HTTP server showing a live dashboard for vmtest runs. The dashboard includes: - Step progress tracker showing all test phases (compile, image prep, QEMU launch, agent connect, tailscale up, test-specific steps) with status icons and elapsed times - Per-VM "virtual monitor" cards showing serial console output streamed in realtime via WebSocket - Per-NIC DHCP status (supporting multi-homed VMs like subnet routers) - Per-node Tailscale status (hidden for non-tailnet VMs) - Test status badge (Running/Passed/Failed) with live elapsed timer - Event log showing all lifecycle events chronologically Architecture follows the existing util/eventbus HTMX+WebSocket pattern: the server pushes HTML fragments with hx-swap-oob attributes over a WebSocket, and HTMX routes them to the correct DOM elements by ID. Key components: - vmstatus.go: Step tracker (Begin/End lifecycle), EventBus (pub/sub with history for late joiners), VMEvent types, NodeStatus tracking - web.go: HTTP server, WebSocket handler, template loading, ANSI-to-HTML conversion via robert-nix/ansihtml, deterministic port selection - assets/: HTML templates, CSS, HTMX library (copied from eventbus) - vnet/vnet.go: DHCP event callback on Server for observing DHCP lifecycle - qemu.go: Console log file tailing with manual offset-based reading Usage: go test ./tstest/natlab/vmtest/ --run-vm-tests --vmtest-web=:0 -v When using :0, a deterministic port based on the test name is tried first so re-runs get the same URL, falling back to OS-assigned on conflict.

Tailscale
Private WireGuard® networks made easy
Overview
This repository contains the majority of Tailscale's open source code.
Notably, it includes the tailscaled daemon and
the tailscale CLI tool. The tailscaled daemon runs on Linux, Windows,
macOS, and to varying degrees
on FreeBSD and OpenBSD. The Tailscale iOS and Android apps use this repo's
code, but this repo doesn't contain the mobile GUI code.
Other Tailscale repos of note:
- the Android app is at https://github.com/tailscale/tailscale-android
- the Synology package is at https://github.com/tailscale/tailscale-synology
- the QNAP package is at https://github.com/tailscale/tailscale-qpkg
- the Chocolatey packaging is at https://github.com/tailscale/tailscale-chocolatey
For background on which parts of Tailscale are open source and why, see https://tailscale.com/opensource/.
Using
We serve packages for a variety of distros and platforms at https://pkgs.tailscale.com.
Other clients
The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers. The GUI wrappers on non-open source platforms are themselves not open source.
Building
We always require the latest Go release, currently Go 1.26. (While we build releases with our Go fork, its use is not required.)
go install tailscale.com/cmd/tailscale{,d}
If you're packaging Tailscale for distribution, use build_dist.sh
instead, to burn commit IDs and version info into the binaries:
./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled
If your distro has conventions that preclude the use of
build_dist.sh, please do the equivalent of what it does in your
distro's way, so that bug reports contain useful version information.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
Contributing
PRs welcome! But please file bugs. Commit messages should reference bugs.
We require Developer Certificate of
Origin
Signed-off-by lines in commits.
See commit-messages.md (or skim git log) for our commit message style.
