def create_node(self, **kwargs): (source)

overrides libcloud.compute.base.NodeDriver.create_node

overridden in libcloud.compute.drivers.opennebula.OpenNebula_2_0_NodeDriver

Create a new OpenNebula node.

See NodeDriver.create_node for more keyword args.

Parameters	networks	List of virtual networks to which this node should connect. (optional) (type: `OpenNebulaNetwork` or `list` of `OpenNebulaNetwork`s)
Returns	Instance of a newly created node. (type: `Node`)

def destroy_node(self, node): (source)

overrides libcloud.compute.base.NodeDriver.destroy_node

overridden in libcloud.compute.drivers.opennebula.OpenNebula_2_0_NodeDriver

Destroy a node.

Depending upon the provider, this may destroy all data associated with the node, including backups.

Parameters	node	The node to be destroyed (type: `Node`)
Returns	`bool` True if the destroy was successful, otherwise False

def list_images(self, location=None): (source)

Parameters	location	The location at which to list images (type: `NodeLocation`)
Returns	`list` of `NodeImage` objects

def list_sizes(self, location=None): (source)

overrides libcloud.compute.base.NodeDriver.list_sizes

overridden in libcloud.compute.drivers.opennebula.OpenNebula_2_0_NodeDriver

Return list of sizes on a provider.

See NodeDriver.list_sizes for more args.

Returns List of compute node sizes supported by the cloud provider. (type: list of OpenNebulaNodeSize)

def ex_list_networks(self, location=None): (source)

List virtual networks on a provider.

Parameters	location	Location from which to request a list of virtual networks. (optional) (type: `NodeLocation`)
Returns	List of virtual networks available to be connected to a compute node. (type: `list` of `OpenNebulaNetwork`)

def ex_node_action(self, node, action): (source)

Parameters	node	Compute node instance. (type: `Node`)
	action	Action to be carried out on the compute node. (type: `str`)
Returns	False if an HTTP Bad Request is received, else, True is returned. (type: `bool`)
