+Multicast packets (mDNS) are not sent out of VM
+Description of problem:
+The app is sending multicast packets (mDNS), but they are not sent out of VM.
+Here is the configuration of the network: `-netdev user,id=net0,hostfwd=tcp::2222-:22,hostfwd=tcp::50051-:50051,hostfwd=tcp::50050-:50050`
+Steps to reproduce:
+1. Install arduino-cli from https://github.com/arduino/arduino-cli/releases (eg. 0.20.2)
+2. `arduino-cli config init`
+3. `vi ~/.arduino15/arduino-cli.yaml`
+4. edit it to have it as follows:
+```
+board_manager:
+  additional_urls: ["http://arduino.esp8266.com/stable/package_esp8266com_index.json"]
+daemon:
+  port: "50051"
+directories:
+  data: /root/app/data
+  downloads: /root/app/downloads
+  user: /root/app/user
+library:
+  enable_unsafe_install: false
+logging:
+  file: ""
+  format: text
+  level: info
+metrics:
+  addr: :9090
+  enabled: false
+output:
+  no_color: false
+sketch:
+  always_export_binaries: false
+updater:
+  enable_notification: true
+```
+
+5. `arduino-cli core update-index`
+6. `arduino-cli core install esp8266:esp8266`
+7. `arduino-cli board list -v`
+
+This will give an output similar to:
+```

+
+Note `builtin:mdns-discovery` discovery started. It is expected to send the packets as follows (the screenshot from the host with Wireshark):
+
+![Снимок_экрана_2022-01-11_в_22.49.58](/uploads/4c2783c84aaa323bc9dfbca127494768/Снимок_экрана_2022-01-11_в_22.49.58.png)
+
+The screenshot is taken if running the same app (but for macOS) from the host and **i can't see the packets sent if executed from the QEMU guest os**.
+I believe i either configured it the wrong way (`-netdev user,id=net0,...`) or it's a QEMU bug.
+Additional information:
+I've tested on macOS host with qemu 6.0.0 and on Linux (Android) host with qemu 6.1.0 and both were not working.
+
+the network interface seems to be configured for multicasting:
+```

+
+It might be easier to skip using arduino-cli and just use any mdns discovery app.
