Add some sort of server information about our failed ssh_connect
attempts. Currently we don't expose any information about the host.

Nodepool
Nodepool is a service used by the OpenStack CI team to deploy and manage a pool of devstack images on a cloud server for use in OpenStack project testing.
Developer setup
Install dependencies:
sudo apt-get update
sudo apt-get -qy install git mysql-server libmysqlclient-dev g++\
python-dev python-pip libffi-dev libssl-dev qemu-utils\
libxml2-dev libxslt1-dev python-lxml
mkdir src
cd ~/src
git clone git://git.openstack.org/openstack-infra/system-config
git clone git://git.openstack.org/openstack-infra/nodepool
cd nodepool
sudo pip install -U -r requirements.txt
sudo pip install -e .If you're testing a specific patch that is already in gerrit, you will also want to install git-review and apply that patch while in the nodepool directory, ie:
git review -x XXXXXCreate or adapt a nodepool yaml file. You can adapt an infra/system-config one, or fake.yaml as desired. Note that fake.yaml's settings won't Just Work - consult ./modules/openstack_project/templates/nodepool/nodepool.yaml.erb in the infra/system-config tree to see a production config.
If the cloud being used has no default_floating_pool defined in nova.conf, you will need to define a pool name using the nodepool yaml file to use floating ips.
Set up database for interactive testing:
mysql -u root
mysql> create database nodepool;
mysql> GRANT ALL ON nodepool.* TO 'nodepool'@'localhost';
mysql> flush privileges;Set up database for unit tests:
mysql -u root
mysql> grant all privileges on *.* to 'openstack_citest'@'localhost' identified by 'openstack_citest' with grant option;
mysql> flush privileges;
mysql> create database openstack_citest;Export variable for your ssh key so you can log into the created instances:
export NODEPOOL_SSH_KEY=`cat ~/.ssh/id_rsa.pub | awk '{print $2}'`Start nodepool with a demo config file (copy or edit fake.yaml to contain your data):
export STATSD_HOST=127.0.0.1
export STATSD_PORT=8125
nodepoold -d -c tools/fake.yamlAll logging ends up in stdout.
Use the following tool to check on progress:
nodepool image-listAfter each run (the fake nova provider is only in-memory):
mysql> delete from snapshot_image; delete from node;
