clean_up_instance(task)[source]

Cleans up the boot of instance.

This method cleans up the environment that was setup for booting the instance. It unlinks the instance kernel/ramdisk in node’s directory in tftproot and removes the PXE config.

Parameters

task – a task from TaskManager.

Returns

None

ipxe_enabled = True
prepare_instance(task)[source]

Prepares the boot of instance.

This method prepares the boot of the instance after reading relevant information from the node’s instance_info. In case of netboot, it updates the dhcp entries and switches the PXE config. In case of localboot, it cleans up the PXE config.

Parameters

task – a task from TaskManager.

Returns

None

prepare_ramdisk(task, ramdisk_params)[source]

Prepares the boot of Ironic ramdisk using PXE.

This method prepares the boot of the deploy or rescue kernel/ramdisk after reading relevant information from the node’s driver_info and instance_info.

Parameters
  • task – a task from TaskManager.

  • ramdisk_params – the parameters to be passed to the ramdisk. pxe driver passes these parameters as kernel command-line arguments.

Returns

None

Raises

MissingParameterValue, if some information is missing in node’s driver_info or instance_info.

Raises

InvalidParameterValue, if some information provided is invalid.

Raises

IronicException, if some power or set boot boot device operation failed on the node.

validate(task)[source]

Validate the PXE-specific info for booting deploy/instance images.

This method validates the PXE-specific info for booting the ramdisk and instance on the node. If invalid, raises an exception; otherwise returns None.

Parameters

task – a task from TaskManager.

Returns

None

Raises

InvalidParameterValue, if some parameters are invalid.

Raises

MissingParameterValue, if some required parameters are missing.
