Re: [ovirt-users] Add multiple files to a VM via cloud-init

The "custom_script" element doesn't work in combination with cloud-init and run once. To make it work you have to use cloud-init and a file element containing your custom script. Here you have an example: #!/usr/bin/python import base64 import re from ovirtsdk.api import API from ovirtsdk.xml import params # A simple function to encode using base64 and now new lines: def encode(s): return re.sub("\s+", "", base64.encodestring(s)) # Connect to the server: api = API( url="https://engine35.example.com/ovirt-engine/api";, username="admin@internal", password="redhat123", insecure=True, debug=True ) # Find the virtual machine: myvm = api.vms.get(name="myvm") # Prepare the cloud-init custom script to write files: myscript = """\ write_files: """ # Append one file: myscript += """\ - encoding: b64 content: %s owner: root:root path: /etc/firstfile.txt permissions: '0644' """ % encode("The content of the first file") # Append another file: myscript += """\ - encoding: b64 content: %s owner: root:root path: /etc/secondfile.txt permissions: '0644' """ % encode("The content of the second file") # Prepare the action to trigger initialization using cloud-init: action = params.Action( vm=params.VM( initialization=params.Initialization( cloud_init=params.CloudInit( files=params.Files( file=[ params.File( name="myscript", type_="plaintext", content=myscript ) ] ) ) ) ) ) # Start the virtual machine: myvm.start(action) # Disconnect from the server: api.disconnect() Regarding the problem with the root password we have a bug in 3.5 that makes this fail. See here: https://bugzilla.redhat.com/1156155 The problem is that we are not passing the user name to cloud-init, and as a result it is changing the default cloud-init user password, not the root pssword. To workaround the issue you can edit the "/etc/cloud/cloud.cfg" file of the VM and change the default user name: system_info: distro: ... default_user: name: root <-- Change this from "fedora" or "cloud-init" to root
