Configuration drive format
|
|
|
|
Configuration drive format that will contain metadata attached to the
|
|
instance when it boots.
|
|
|
|
Possible values:
|
|
|
|
* iso9660: A file system image standard that is widely supported across
|
|
operating systems. NOTE: Mind the libvirt bug
|
|
(https://bugs.launchpad.net/nova/+bug/1246201) - If your hypervisor
|
|
driver is libvirt, and you want live migrate to work without shared storage,
|
|
then use VFAT.
|
|
* vfat: For legacy reasons, you can configure the configuration drive to
|
|
use VFAT format instead of ISO 9660.
|
|
|

Related options:

|
|
|
* This option is meaningful when one of the following alternatives occur:
|
|
1. force_config_drive option set to 'true'
|
|
2. the REST API call to create the instance contains an enable flag for
|
|
config drive option
|
|
3. the image used to create the instance requires a config drive,
|
|
this is defined by img_config_drive property for that image.
|
|
* A compute node running Hyper-V hypervisor can be configured to attach
|
|
configuration drive as a CD drive. To attach the configuration drive as a CD
|
|
drive, set config_drive_cdrom option at hyperv section, to true.

Force injection to take place on a config drive

When this option is set to true configuration drive functionality will be

drives via the REST API or image metadata properties.

Possible values:

* True: Force to use of configuration drive regardless the user's input in the

REST API call.
|

* False: Do not force use of configuration drive. Config drives can still be

enabled via the REST API or image metadata properties.

nova-compute service, you do not need to set this flag.
