Using mosquitto in a virtual environment

Configuration
1

When 0.24 came out, I rebuilt from scratch using the AIO installer on a fresh Raspian installation, but reusing my old yaml configuration. Almost everything works except for the mqqt component, and I am logging

16-07-21 17:47:35 homeassistant.components.mqtt: Disconnected from MQTT (1). Trying to reconnect in 1s

My configuration file includes

mqtt:
  broker: 10.0.0.26
  client_id: home-assistant-1
  username: *****
  password: *****
   
device_tracker:
  platform: owntracks
  max_gps_accuracy: 200

I’m missing something, either in the mosquitto configuration or the HA configuration.

Edit out your password, and edit in code tags around your config (and make sure your spacing is reflected accurately)
