Parameters for customizing the core template collection for a Red Hat OpenStack Platform overcloud
Abstract
About this guide
This guide is automatically generated from comments embedded in the upstream OpenStack source code. Therefore, not all of the parameters listed in this guide are supported in a production environment. To locate information about actual supported parameters, see the relevant guide that describes your supported use-case.
Making open source more inclusive
Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.

This parameter should be used if the default (which comes from the InternalTLSVncProxyCAFile parameter) is not desired. The current default reflects TripleO’s default CA, which is FreeIPA. It will only be used if internal TLS is enabled. |
| Override the private key size used when creating the certificate for this service. |
|

|

|
Set to "True" to convert non-raw cached base images to raw format. Set to "False" if you have a system with slow I/O or low available space, trading the higher CPU requirements of compression for that of minimized input bandwidth. Notes:: - The Compute service removes any compression from the base image during compression, to avoid CPU bottlenecks. Converted images cannot have backing files, which might be a security issue. - The raw image format uses more space than other image formats, for example, qcow2. Raw base images are always used with libvirt_images_type=lvm. The default value is |
| Specifies the number of seconds to wait between runs of the image cache manager, which impacts base image caching on Compute nodes. This period is used in the auto removal of unused cached images configured with remove_unused_base_images and remove_unused_original_minimum_age_seconds.
Set to "0" to run at the default interval of 60 seconds (not recommended). The default value is |
| Maximum number of Compute nodes to trigger image precaching in parallel. When an image precache request is made, Compute nodes are contacted {by who/which service} to initiate the download.
Higher numbers will cause more computes to work in parallel and may result in reduced time to complete the operation, but may also DDoS the image service. Lower numbers will result in more sequential operation, lower image service load, but likely longer runtime to completion. The default value is |
|
Set to "True" to automatically remove unused base images from the cache at intervals configured by using image_cache_manager_interval. Images are defined as unused if they have not been accessed during the time specified by using remove_unused_original_minimum_age_seconds. The default value is |
|
Specifies the minimum age that an unused resized base image must be to be removed from the cache, in seconds. Unused unresized base images younger than this will not be removed. The default value is |
| Specifies the preallocation mode for libvirt instance disks. Set to one of the following valid values:: - none - No storage is provisioned at instance start. - space - Storage is fully allocated at instance start using fallocate, which can help with both space guarantees and I/O performance.
Even when not using CoW instance disks, the copy each instance gets is sparse and so the instance might fail unexpectedly at run time with ENOSPC. By running fallocate(1) on the instance disk images, the Compute service immediately and efficiently allocates the space for them in the file system, if supported. Run time performance should also be improved because the file system does not have to dynamically allocate blocks at run time, which reduces CPU overhead and file fragmentation. The default value is |
|
Libvirt domain type. Defaults to kvm. The default value is |
| List of optional environment variables. |
| List of optional volumes. |
|
Delays the startup of nova-compute service after compute node is booted. This is to give a chance to ceph to get back healthy before booting instances after and overcloud reboot. The default value is |
|
Set to "True" to use CoW (Copy on Write) images in cqow2 format for libvirt instance disks. With CoW, depending on the backing store and host caching, there might be better concurrency achieved by having each instance operate on its own copy. Set to "False" to use the raw format. Raw format uses more space for common parts of the disk image. The default value is |
|

Defaults to "True" to slow down the instance CPU until the memory copy process is faster than the instance’s memory writes when the migration performance is slow and might not complete.

Indicates that the nova-metadata API service has been deployed per-cell, so that we can have better performance and data isolation in a multi-cell deployment. Users should consider the use of this configuration depending on how OpenStack Networking (neutron) is setup. If networks span cells, you might need to run nova-metadata API service globally. If your networks are segmented along cell boundaries, then you can run nova-metadata API service per cell. When running nova-metadata API service per cell, you should also configure each OpenStack Networking (neutron) metadata-agent to point to the corresponding nova-metadata API service. The default value is |
|
Maximum number of disk devices allowed to attach to a single server. Note that the number of disks supported by an server depends on the bus used. For example, the ide disk bus is limited to 4 attached devices. The configured maximum is enforced during server create, rebuild, evacuate, unshelve, live migrate, and attach volume. Operators changing this parameter on a compute service that is hosting servers should be aware that it could cause rebuilds to fail, if the maximum is decreased lower than the number of devices already attached to servers.
