Nova and DevStack

This is a rough guide to various configuration parameters for nova running with DevStack.

nova-serialproxy

In Juno, nova implemented a spec to allow read/write access to the serial console of an instance via nova-serialproxy.

The service can be enabled by adding n-sproxy to ENABLED_SERVICES. Further options can be enabled via local.conf, e.g.

[[post-config|$NOVA_CONF]]
[serial_console]
#
# Options defined in nova.cmd.serialproxy
#

# Host on which to listen for incoming requests (string value)
#serialproxy_host=0.0.0.0

# Port on which to listen for incoming requests (integer
# value)
#serialproxy_port=6083


#
# Options defined in nova.console.serial
#

# Enable serial console related features (boolean value)
#enabled=false
# Do not set this manually.  Instead enable the service as
# outlined above.

# Range of TCP ports to use for serial ports on compute hosts
# (string value)
#port_range=10000:20000

# Location of serial console proxy. (string value)
#base_url=ws://127.0.0.1:6083/

# IP address on which instance serial console should listen
# (string value)
#listen=127.0.0.1

# The address to which proxy clients (like nova-serialproxy)
# should connect (string value)
#proxyclient_address=127.0.0.1

Enabling the service is enough to be functional for a single machine DevStack.

These config options are defined in nova.console.serial and nova.cmd.serialproxy.
