More on this...

So while waiting for post moderation, I went to the quick start guide and copied all of that text into a new local.conf

[[local|localrc]]
# Multi-host settings
MULTI_HOST=False
HOST_IP=YOUR_IP_CONFIG
SERVICE_HOST=$HOST_IP
DATABASE_TYPE=mysql
MYSQL_HOST=$HOST_IP
RABBIT_HOST=$HOST_IP

# Passwords
DATABASE_PASSWORD=123
ADMIN_PASSWORD=123
MYSQL_PASSWORD=123
RABBIT_PASSWORD=123
SERVICE_PASSWORD=123
SERVICE_TOKEN=ADMIN

#FIXED_RANGE=192.168.128.0/24
#IPV4_ADDRS_SAFE_TO_USE=192.168.128.0/24
#GIT_BASE=/opt/git
disable_service n-net
disable_service tempest
disable_service heat
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
enable_service neutron
enable_service n-novnc
enable_plugin cyborg git://git.openstack.org/openstack/cyborg
NOVA_VNC_ENABLED=True
NOVNCPROXY_URL="http://$SERVICE_HOST:6080/vnc_auto.html"
VNCSERVER_LISTEN=0.0.0.0
VNCSERVER_PROXYCLIENT_ADDRESS=$SERVICE_HOST
RECLONE=False
#enable Logging
LOGFILE=/opt/stack/logs/stack.sh.log
VERBOSE=True
LOG_COLOR=True
LOGDIR=/opt/stack/logs

substituting HOST_IP for the servers IP.

That seems to be working right now.

So perhaps the issue I'm reporting is that the docs for single machine maybe imply a simpler config file than what is necessary:

Run DevStack¶

Now to configure stack.sh. DevStack includes a sample in devstack/samples/local.conf. Create local.conf as shown below to do the following:

    Set FLOATING_RANGE to a range not used on the local network, i.e. 192.168.1.224/27. This configures IP addresses ending in 225-254 to be used as floating IPs.
    Set FIXED_RANGE and FIXED_NETWORK_SIZE to configure the internal address space used by the instances.
    Set FLAT_INTERFACE to the Ethernet interface that connects the host to your local network. This is the interface that should be configured with the static IP address mentioned above.
    Set the administrative password. This password is used for the admin and demo accounts set up as OpenStack users.
    Set the MySQL administrative password. The default here is a random hex string which is inconvenient if you need to look at the database directly for anything.
    Set the RabbitMQ password.
    Set the service password. This is used by the OpenStack services (Nova, Glance, etc) to authenticate with Keystone.

local.conf should look something like this:

[[local|localrc]]
FLOATING_RANGE=192.168.1.224/27
FIXED_RANGE=10.11.12.0/24
FIXED_NETWORK_SIZE=256
FLAT_INTERFACE=eth0
ADMIN_PASSWORD=supersecret
DATABASE_PASSWORD=iheartdatabases
RABBIT_PASSWORD=flopsymopsy
SERVICE_PASSWORD=iheartksl

I'm posting this so that anyone who has the same problem and can't find an answer is hopefully helped over the hump.

Best!
