# == Class: nova::compute::libvirt_guests
|
|
#
|
|
# manages configuration for starting running instances when compute node
|
|
# gets rebooted.
|
|
#
|
|
# === Parameters:
|
|
#
|
|
# [*enabled*]
|
|
# (optional) Whether the libvirt-guests service will be run
|
|
# Defaults to false
|
|
#
|
|
# [*package_ensure*]
|
|
# (optional) The state of libvirt packages
|
|
# Defaults to 'present'
|
|
#
|
|
# [*on_boot*]
|
|
# (optional) libvirt-guests parameter - action taken on host boot
|
|
# - start all guests which were running on shutdown are started on boot
|
|
# regardless on their autostart settings
|
|
# - ignore libvirt-guests init script won't start any guest on boot, however,
|
|
# guests marked as autostart will still be automatically started by
|
|
# libvirtd
|
|
# Defaults to 'ignore'
|
|
#
|
|
# [*on_shutdown*]
|
|
# (optional) libvirt-guests parameter - action taken on host shutdown
|
|
# - suspend all running guests are suspended using virsh managedsave
|
|
# - shutdown all running guests are asked to shutdown. Please be careful with
|
|
# this settings since there is no way to distinguish between a
|
|
# guest which is stuck or ignores shutdown requests and a guest
|
|
# which just needs a long time to shutdown. When setting
|
|
# ON_SHUTDOWN=shutdown, you must also set SHUTDOWN_TIMEOUT to a
|
|
# value suitable for your guests.
|
|
# Defaults to 'shutdown'
|
|
#
|
|
# [*shutdown_timeout*]
|
|
# (optional) Number of seconds we're willing to wait for a guest to shut
|
|
# down. If parallel shutdown is enabled, this timeout applies as a timeout
|
|
# for shutting down all guests on a single URI defined in the variable URIS.
|
|
# If this is 0, then there is no time out (use with caution, as guests might
|
|
# not respond to a shutdown request). The default value is 300 seconds
|
|
# (5 minutes).
|
|
# Defaults to 300.
|
|
#
|
|
# [*manage_service*]
|
|
# (optional) Whether to start/stop the service
|
|
# Defaults to false
