Defined in:

Overview

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

Parameters:

  • never_download_image_if_on_rbd (Any) (defaults to: $::os_service_default)
  • ensure_libvirt_rbd_instance_dir_cleanup (Any) (defaults to: $::os_service_default)
  • enable_qemu_monitor_announce_self (Any) (defaults to: $::os_service_default)
  • wait_for_vif_plugged_event_during_hard_reboot (Any) (defaults to: $::os_service_default)
  • disable_compute_service_check_for_ffu (Any) (defaults to: $::os_service_default)
  • skip_hypervisor_version_check_on_lm (Any) (defaults to: $::os_service_default)
  • enable_numa_live_migration (Any) (defaults to: undef)
