# This file provides devstack with the environment and utilities to
# control nova-compute's baremetal driver.
# It sets reasonable defaults to run within a single host,
# using virtual machines in place of physical hardware.
# However, by changing just a few options, devstack+baremetal can in fact
# control physical hardware resources on the same network, if you know
# the MAC address(es) and IPMI credentials.
#
# At a minimum, to enable the baremetal driver, you must set these in loclarc:
# VIRT_DRIVER=baremetal
# ENABLED_SERVICES="$ENABLED_SERVICES,baremetal"
#
#
# We utilize diskimage-builder to create a ramdisk, and then
# baremetal driver uses that to push a disk image onto the node(s).
#
# Below we define various defaults which control the behavior of the
# baremetal compute service, and inform it of the hardware it will control.
#
# Below that, various functions are defined, which are called by devstack
# in the following order:
#
# before nova-cpu starts:
# - prepare_baremetal_toolchain
# - configure_baremetal_nova_dirs
#
# after nova and glance have started:
# - build_and_upload_baremetal_deploy_k_and_r $token
# - create_baremetal_flavor $BM_DEPLOY_KERNEL_ID $BM_DEPLOY_RAMDISK_ID
# - upload_baremetal_image $url $token
# - add_baremetal_node <first_mac> <second_mac>
# Save trace setting
