This change introduces a new compute_driver parameter for all compute driver manifests. This will allow a user to override the compute_driver config value by its own instead of forking or monkey-patching the manifests. It also changes the compute_driver config value of Ironic for ironic.IronicDriver which also works and better fit the config value style already used in the other manifests. Common use case for this parameter is to allow the use of a local or derivative version of a driver which adds features and/or bug fixes.

|
|
#
|
|
# === Parameters:
|
|
#
|
|
# [*libvirt_virt_type*]
|
|
# (optional) Libvirt domain type. Options are: kvm, lxc, qemu, uml, xen
|
|
# Defaults to 'kvm'
|
|
#
|
|
# [*vncserver_listen*]
|
|
# (optional) IP address on which instance vncservers should listen
|
|
# Defaults to '127.0.0.1'
|
|
#
|
|
# [*migration_support*]
|
|
# (optional) Whether to support virtual machine migration
|
|
# Defaults to false
|
|
#
|
|
# [*libvirt_cpu_mode*]
|
|
# (optional) The libvirt CPU mode to configure. Possible values
|
|
# include custom, host-model, none, host-passthrough.
|
|
# Defaults to 'host-model' if libvirt_virt_type is set to either
|
|
# kvm or qemu, otherwise defaults to 'none'.
|
|
#
|
|
# [*libvirt_disk_cachemodes*]
|
|
# (optional) A list of cachemodes for different disk types, e.g.
|
|
# ["file=directsync", "block=none"]
|
|
# If an empty list is specified, the disk_cachemodes directive
|
|
# will be removed from nova.conf completely.
|
|
# Defaults to an empty list
|
|
#

|
#
|
|
# [*libvirt_inject_partition*]
|
|
# (optional) The partition to inject to : -2 => disable, -1 => inspect
|
|
# (libguestfs only), 0 => not partitioned, >0 => partition
|
|
# number (integer value)
|
|
# Defaults to -2
|
|
#
|
|
# [*remove_unused_base_images*]
|
|
# (optional) Should unused base images be removed?
|
|
# If undef is specified, remove the line in nova.conf
|
|
# otherwise, use a boolean to remove or not the base images.
|
|
# Defaults to undef
|
|
#
|
|
# [*remove_unused_kernels*]
|
|
# (optional) Should unused kernel images be removed?
|
|
# This is only safe to enable if all compute nodes
|
|
# have been updated to support this option.
|
|
# If undef is specified, remove the line in nova.conf
|
|
# otherwise, use a boolean to remove or not the kernels.
|
|
# Defaults to undef
|
|
#
|
|
# [*remove_unused_resized_minimum_age_seconds*]
|
|
# (optional) Unused resized base images younger
|
|
# than this will not be removed
|
|
# If undef is specified, remove the line in nova.conf
|
|
# otherwise, use a integer or a string to define after
|
|
# how many seconds it will be removed.
|
|
# Defaults to undef
|
|
#
|
|
# [*remove_unused_original_minimum_age_seconds*]
|
|
# (optional) Unused unresized base images younger

|
|
# otherwise, use a integer or a string to define after
|
|
# how many seconds it will be removed.
|
|
# Defaults to undef
|
|
#
|
|
# [*libvirt_service_name*]
|
|
# (optional) libvirt service name.
|
|
# Defaults to $::nova::params::libvirt_service_name
|
|
#
|
|
# [*compute_driver*]
|
|
# (optional) Compute driver.
|
