Python Bindings for OpenNebula XML-RPC API

Open Nebula Python Bindings

This is an implementation of Open Nebula XML-RPC bindings in Python.

The main goals of this library is completeness and maintainability.

Proxies and generators have been used whenever possible to minimize the impact of API updates, ensuring that the distributed xsd files are the only update required when new API versions are released.

This library is meant to be used together with OpenNebula API documentation:

The XML-RPC API must be used to know which calls to make.

How to use it

Installation

The code is distributed as a package:

pip install pyone

Making Calls

Calls match the API documentation provided by Open Nebula:

import pyone

one = pyone.OneServer("http://one/RPC2", session="oneadmin:onepass" )
hostpool = one.hostpool.info()
host = hostpool.HOST[0]
id = host.ID

Note that the session parameter is automatically included as well as the “one.” prefix to the method.

Returned Objects

The returned types have been generated with PyXB and closely match the XSD specification. You can use the XSD specification as primary documentation while your IDE will offer code completion as you code

marketpool = one.marketpool.info()
m0 = marketpool.MARKETPLACE[0]
print "Markeplace name is " + m0.NAME

Structured Parameters

When making calls, the library will translate flat dictionaries into attribute=value vectors. Such as:

one.host.update(0,  {"LABELS": "HD"}, 1)

When the provided dictionary has a “root” dictionary, it is considered to be root element and it will be translated to XML:

one.vm.update(1,
  {
    'TEMPLATE': {
      'NAME': 'abc',
      'MEMORY': '1024',
      'ATT1': 'value1'
    }
  }, 1)

Building from Source

Note that a Makefile is provided to generate the python bindings
