OpenNebula provides ruby bindings to access the xml-rpc
The opennebula fog extensions provides examples for using Fog with OpenNebula (4.4).
Note: This provider is under construction! This means everything that is provided should work without problems, but there are many features not available yet. Please contribute!
For working with this provider the following pre-requisites are needed:
Ruby version 1.8.x or 1.9.x
fog gem
Working OpenNebula instance with XML-RPC and credentials
This version is tested with OpenNebula 4.4 and the opennebula gem dependency is hardcoded to this version. it should work with version 4.6, but is not tested.
General proceeding:
Connect to one-rpc
create new vm object
fetch a template/flavor from one (this template should be predefined)
assigne the flavor/template to the vm
change the attributes of this flavor/template (name, cpu, memory, nics.…)
save/instantiate the vm
require 'fog' # connect to your one rpc con = Fog::Compute.new( { :provider => 'OpenNebula', :opennebula_username => 'user', :opennebula_password => 'password', :opennebula_endpoint => 'http://oned.domain:2633/RPC2' } ) # list all vms con.servers # list all flavors (templates in OpenNebula slang) con.flavors # get flavor with id 4 con.flavors.get 4 # list all Virtual Networks con.networks con.networks.get 2 # get all usergroups con.groups # create a new vm (creates the object, the vm is not instantiated yet) newvm = con.servers.new # set the flavor of the vm newvm.flavor = con.flavors.get 4 # set the name of the vm newvm.name = "FooBarVM" # set the groupid of the vm newvm.gid = 0 # set cores and memory (MB) newvm.flavor.vcpu = 2 newvm.flavor.memory = 256 # create a new network interface attached to the network with id 1 and virtio as driver/model network = client.networks.get(1) nic = con.interfaces.new({ :vnet => network, :model => "virtio"}) # Attach the new nic to our vm newvm.flavor.nic = [ nic ] # instantiat the new vm newvm.save
tbd
con.groups.get 4
AND everything not mentioned in features or examples ;)
ArgumentError: opennebula is not a recognized compute provider
is the correct gem version included?
