# Image properties that should not be inherited from the instance
# when taking a snapshot.
#
# This option gives an opportunity to select which image-properties
# should not be inherited by newly created snapshots.
#
# Possible values:

#non_inheritable_image_properties = cache_in_nova,bittorrent
# DEPRECATED:
# This option is used to decide when an image should have no external

# image is booted with the property 'kernel_id' with the value
# 'nokernel', Nova assumes the image doesn't require an external kernel
# and ramdisk.
# (string value)
# This option is deprecated for removal since 15.0.0.
# Its value may be silently ignored in the future.
# Reason:
# When an image is booted with the property 'kernel_id' with the value

# DEPRECATED:
# When creating multiple instances with a single request using the

# (so root local disc that is the result of --image being used, and
# any other ephemeral and swap disks). 0 does not mean that images
# will be automatically converted to volumes and boot instances from
# volumes - it just means that all requests that attempt to create a

# Determine if instance should boot or fail on VIF plugging timeout.
#
# Nova sends a port update to Neutron after an instance has been scheduled,
# providing Neutron with the necessary information to finish setup of the port.
# Once completed, Neutron notifies Nova that it has finished setting up the
# port, at which point Nova resumes the boot of the instance since network
# connectivity is now supposed to be present. A timeout will occur if the reply
# is not received after a given interval.
#
# This option determines what Nova does when the VIF plugging timeout event
# happens. When enabled, the instance will error out. When disabled, the
# instance will continue to boot on the assumption that the port is ready.
#
# Possible values:
#
# * True: Instances should fail after VIF plugging timeout
# * False: Instances should continue booting after VIF plugging timeout
# (boolean value)

#
# The image preallocation mode to use.
#
# Image preallocation allows storage for instance images to be allocated up
# front
# when the instance is initially provisioned. This ensures immediate feedback is
# given if enough space isn't available. In addition, it should significantly
# improve performance on writes to new blocks and may even improve I/O
# performance to prewritten blocks due to reduced fragmentation.

# A list of vendordata providers.
#
# vendordata providers are how deployers can provide metadata via configdrive
# and metadata that is specific to their deployment. There are currently two
# supported providers: StaticJSON and DynamicJSON.
#
# StaticJSON reads a JSON file configured by the flag vendordata_jsonfile_path
# and places the JSON from that file into vendor_data.json and
# vendor_data2.json.
#
# DynamicJSON is configured via the vendordata_dynamic_targets flag, which is
# documented separately. For each of the endpoints specified in that flag, a
# section is added to the vendor_data2.json.
#
# For more information on the requirements for implementing a vendordata
# dynamic endpoint, please see the vendordata.rst file in the nova developer
# reference.

# Specific cache modes to use for different disk types.
#
# For example: file=directsync,block=none,network=writeback
#
# For local or direct-attached storage, it is recommended that you use
# writethrough (default) mode, as it ensures data integrity and has acceptable
# I/O performance for applications running in the guest, especially for read
# operations. However, caching mode none is recommended for remote NFS storage,
# because direct I/O operations (O_DIRECT) perform better than synchronous I/O
# operations (with O_SYNC). Caching mode none effectively turns all guest I/O
# operations into direct I/O operations on the host, which is the NFS client in
# this environment.
#
# Possible cache modes:
#
# * default: Same as writethrough.
# * none: With caching mode set to none, the host page cache is disabled, but
# the disk write cache is enabled for the guest. In this mode, the write
# performance in the guest is optimal because write operations bypass the host
# page cache and go directly to the disk write cache. If the disk write cache
# is battery-backed, or if the applications or storage stack in the guest
# transfer data properly (either through fsync operations or file system
# barriers), then data integrity can be ensured. However, because the host
# page cache is disabled, the read performance in the guest would not be as
# good as in the modes where the host page cache is enabled, such as
# writethrough mode.
# * writethrough: writethrough mode is the default caching mode. With
# caching set to writethrough mode, the host page cache is enabled, but the
# disk write cache is disabled for the guest. Consequently, this caching mode
# ensures data integrity even if the applications and storage stack in the
# guest do not transfer data to permanent storage properly (either through
# fsync operations or file system barriers). Because the host page cache is
# enabled in this mode, the read performance for applications running in the
# guest is generally better. However, the write performance might be reduced
# because the disk write cache is disabled.
# * writeback: With caching set to writeback mode, both the host page cache
# and the disk write cache are enabled for the guest. Because of this, the
# I/O performance for applications running in the guest is good, but the data
# is not protected in a power failure. As a result, this caching mode is
# recommended only for temporary data where potential data loss is not a
# concern.
# * directsync: Like "writethrough", but it bypasses the host page cache.
# * unsafe: Caching mode of unsafe ignores cache transfer operations
# completely. As its name implies, this caching mode should be used only for
# temporary data where data loss is not a concern. This mode can be useful for
# speeding up guest installations, but you should switch to another caching
# mode in production environments.

#
# * Virtualization driver must be libvirt
# * spice.enabled set to True
# * vnc.enabled set to False
# * update html5proxy_base_url

#
# This is an advanced feature which allows the hypervisor to signal to the

# Number of seconds to wait for agent's reply to a request.
#
# Nova configures/performs certain administrative actions on a server with the
# help of an agent that's installed on the server. The communication between
# Nova and the agent is achieved via sharing messages, called records, over
# xenstore, a shared storage across all the domains on a Xenserver host.
# Operations performed by the agent on behalf of nova are: 'version','
# key_init',
# 'password','resetnetwork','inject_file', and 'agentupdate'.
#
# To perform one of the above operations, the xapi 'agent' plugin writes the
# command and its associated parameters to a certain location known to the
# domain
# and awaits response. On being notified of the message, the agent performs
# appropriate actions on the server and writes the result back to xenstore. This
# result is then read by the xapi 'agent' plugin to determine the
# success/failure
# of the operation.
#
# This config option determines how long the xapi 'agent' plugin shall wait to
