Hassio in Docker - SSH Key - Host key verification failed - KVM Integration

Configuration
2

I eventually figured this out, I can now control (turn on, turn off, reboot, etc) my KVM VM’s with Alexa.
Here’s how I did it (this is also using the excellent Nabu Casa).

  1. SSH in to HASSIO
  2. $ docker ps -a
    (this is to find the correct docker ID, the line for me was homeassistant/qemux86-64-
    homeassistant:0.103.5, whihc gave me the ID of 58da6a62a2de)
  3. $ docker exec -it 7de1331b3d67 /bin/bash
    (this will give you shell access to the docker instance)
  4. $ mkdir /config/ssh
  5. $ ssh-keygen -t rsa -f /config/ssh/id_rsa
  6. $ ssh-copy-id -i /config/ssh/id_rsa [email protected]
    (replace the user and IP of the KVM host, this will copy the key to the KVM host)
  7. I then created some .sh script files in /config/scripts22/vm_turn_on.sh, etc
  8. Contents os turn_vm_on.sh:
#!/bin/bash
ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -i /config/ssh/id_rsa [email protected] -tt 'bash -l -c "virsh start gaminigVM"'
  1. In shell_commands.yaml:
    vm_turn_on: '/config/scripts22/vm_turn_on.sh'
  2. Then in scripts.yaml:
vm_turn_on:
  sequence:
    service: shell_command.vm_turn_on
  1. Then on Alexa, say “discover new devices”, and it should discover ‘vm_turn_on’.

Hope this helps :slight_smile:
