Raises:

FailedToCleanDHCPOpts

get_ip_addresses(task)

Get IP addresses for all ports/portgroups in task.

Parameters:

task – A TaskManager instance.

Returns:

List of IP addresses associated with task’s ports and portgroups.

supports_ipxe_tag()

Whether the provider will correctly apply the ‘ipxe’ tag.

When iPXE makes a DHCP request, does this provider support adding the tag ipxe or ipxe6 (for IPv6). When the provider returns True, options can be added which filter on these tags.

Returns:

True when the driver supports tagging iPXE DHCP requests

abstract update_dhcp_opts(task, options, vifs=None)

Send or update the DHCP BOOT options for this node.

Parameters:

• task – A TaskManager instance.

• options –

  this will be a list of dicts, e.g.

  [{'opt_name': '67',
    'opt_value': 'pxelinux.0',
    'ip_version': 4},
   {'opt_name': '66',
    'opt_value': '123.123.123.456',
    'ip_version': 4}]
  

• vifs –

  A dict with keys ‘ports’ and ‘portgroups’ and dicts as values. Each dict has key/value pairs of the form <ironic UUID>:<neutron port UUID>. e.g.

  {'ports': {'port.uuid': vif.id},
   'portgroups': {'portgroup.uuid': vif.id}}
  

  If the value is None, will get the list of ports/portgroups from the Ironic port/portgroup objects.

Raises:

FailedToUpdateDHCPOptOnPort

abstract update_port_dhcp_opts(port_id, dhcp_options, context=None)

Update one or more DHCP options on the specified port.

Parameters:

• port_id – designate which port these attributes will be applied to.

• dhcp_options –

  this will be a list of dicts, e.g.

  [{'opt_name': '67',
    'opt_value': 'pxelinux.0',
    'ip_version': 4},
   {'opt_name': '66',
    'opt_value': '123.123.123.456',
    'ip_version': 4}]
  

• context (ironic.common.context.RequestContext) – request context

Raises:
