# == 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 $facts['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 $facts['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 $facts['os_service_default']
#
# [*qemu_monitor_announce_self_count*]
# (Optional) The total number of times to send the announce_self command to
# the QEMU monitor when enable_qemu_monitor_announce_self is enabled.
# Defaults to $facts['os_service_default']
#
# [*qemu_monitor_announce_self_interval*]
# (Optional) The number of seconds to wait before re-sending the announce_self
# command to the QEMU monitor.
# Defaults to $facts['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 $facts['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 $facts['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 $facts['os_service_default']
#
# [*skip_cpu_compare_on_dest*]
# (Optional) With the libvirt driver, during live migration, skip comparing guest CPU
# with the destination host. When using QEMU >= 2.9 and libvirt >=
# 4.4.0, libvirt will do the correct thing with respect to checking CPU
# compatibility on the destination host during live migration.
# Defaults to $facts['os_service_default']
#
# [*skip_cpu_compare_at_startup*]
# (Optional) This will skip the CPU comparison call at the startup of Compute
# service and lets libvirt handle it.
# Defaults to $facts['os_service_default']
#
# DEPRECATED
#
# [*enable_numa_live_migration*]
# (optional) Whether to enable live migration for NUMA topology instances.
# Defaults to undef
#
