# == Class: nova::workarounds
|
|
#
|
|
# nova workarounds configuration
|
|
#
|
|
# === Parameters:
|
|
#
|
|
# [*never_download_image_if_on_rbd*]
|
|
# (Optional) refuse to boot an instance if it would require downloading from
|
|
# glance and uploading to ceph instead of a COW clone
|
|
# Defaults to $::os_service_default
|
|
#
|
|
# [*ensure_libvirt_rbd_instance_dir_cleanup*]
|
|
# (Optional) Ensure the instance directory is removed during clean up when using
|
|
# rbd. When enabled this workaround will ensure that the instance directory is
|
|
# always removed during cleanup on hosts using ``[libvirt]/images_type=rbd``
|
|
# Defaults to $::os_service_default
|
|
#
|
|
# [*enable_qemu_monitor_announce_self*]
|
|
# (Optional) If it is set to True the libvirt driver will try as a best effort to
|
|
# send the announce-self command to the QEMU monitor so that it generates RARP frames
|
|
# to update network switches in the post live migration phase on the destination.
|
|
# Defaults to $::os_service_default
|
|
#
|
|
# [*wait_for_vif_plugged_event_during_hard_reboot*]
|
|
# (Optional) If set Nova will wait for the Neutron ML2 backend to sent vif
|
|
# plugged events when performing hard reboot.
|
|
# Defaults to $::os_service_default
|
|
#
|
|
# [*disable_compute_service_check_for_ffu*]
|
|
# (Optional) If this is set, the normal safety check for old compute services will
|
|
# be treated as a warning instead of an error. This is only to be enabled to
|
|
# facilitate a Fast-Forward upgrade where new control services are being started
|
|
# before compute nodes have been able to update their service record.
|
|
# Defaults to $::os_service_default
|
|
#
|
|
# [*skip_hypervisor_version_check_on_lm*]
|
|
# (Optional) When this is enabled, it will skip version-checking of
|
|
# hypervisors during live migration.
|
|
# Defaults to $::os_service_default
|
|
#
|
|
# DEPRECATED
|
|
#
|
|
# [*enable_numa_live_migration*]
|
|
# (optional) Whether to enable live migration for NUMA topology instances.
|
|
# Defaults to undef
|
|
#
|
