Logging

LOGDIR=$DEST/logs
LOGFILE=$LOGDIR/stack.sh.log  # why didn't bare name work???

The logging support has been recently revamped to use a more conventional configuration. LOGDIR will default to $DEST/logs and all log files will be found here. LOGFILE will be honored as always, putting the stack.sh trace log in that location; if LOGFILE does not include a path, it becomes $LOGDIR/$LOGFILE.

The services logs (aka screen logs) no longer default to a screen-specific subdirectory, unless SCREEN_LOGDIR is set. It is deprecated and will be removed in the future.

Network Addressing

FIXED_RANGE=10.254.1.0/24

Set FIXED_RANGE away from the default 10.0.0.0/24 because, well, many clouds use 10/8 for various things and some of them start at the beginning. Running DevStack in a cloud VM requires that the DevStack network addresses do not overlap with the host cloud networks. Pick a range that isn't at the top or the bottom to (slightly) reduce the chances of collision. This is safe for the neighborhoods I cloud in.

Services

For my normal workflow, I want debugging bits enabled and services I am not using disabled.

enable_service dstat
disable_service h-eng h-api h-api-cfn h-api-cw
disable_service horizon
#enable_service s-proxy s-object s-container s-account

I typically don't use Heat or Horizon, you know, being the CLI guy and all. Swift is not added by default because it takes a toll on memory use, my laptop is not well-endowed in that area so 2G VMs are necessary whenever possible. In the cloud VMs this is not an issue.

Neutron

# Nova Net
enable_service n-net
disable_Service q-svc q-agt q-dhcp q-l3 q-meta

# Neutron
# NETWORK_GATEWAY must be in the FIXED_RANGE network
#NETWORK_GATEWAY=10.254.1.1
#disable_service n-net
#enable_service q-svc q-agt q-dhcp q-l3 q-meta

Neutron may or may not be the default in DevStack by the time you read this, I've stopped taking chances, I want to know what I get, which by default is Nova Net for as long as possible, again mostly for memory and complexity reasons.

Note that Neutron in the default config requires NETWORK_GATEWAY to be set inside the network defined by FIXED_RANGE. Nova Net does not require this, although it is mostly harmless to define anyway.

Legacy Nova Bits

disable_service n-obj n-crt

n-obj is the Nova Object Service, left over from the euca2ools bundle command's need of an S3 service. That's it. Same with n-crt. They should be removed as defaults soon if not already.
