Set environment for your specific user and tenant

# source ~/keystonerc_<user-name>

---

Gather required parameters

# nova flavor-list
Note the <flavor-ID> from the ID column displayed.

# nova image-list
Note the <image-ID> from the ID column displayed.

# nova keypair-list
Note the <key-name> from the Name column displayed.

# nova secgroup-list
Note the <secgroup> from the Name column displayed.

# nova net-list
Note the <tenant-network-ID> from the ID column for the tenant network (not the external network).

# nova floating-ip-list
Note the <floating-IP> from the Ip column, with "-" in the Fixed IP column, to get an unassociated floating IP.

---

Create a new instance using parameters set above

# nova boot --flavor <flavor-ID> \
                  --image <image-ID> \
                  --key-name <key-name> \
                  --security-groups <secgroup> \
                  --nic <net-id=net-uuid> \
                  <instance-name>

---

Assign a floating IP to the instance created

# nova floating-ip-associate <instance-name> <floating-IP>

---

SSH into the new instance using the floating IP and the private key file for <key-name>

# ssh -i <my-key>.pem <user-name>@<floating-IP>

NOTE:
Full path for <my-key>.pem should be mentioned.
1. Username for the instances will depend on the type of the image.
2. Following are a few examples:
CentOS 6.5 (http://repos.fedorapeople.org/repos/openstack/guest-images/centos-6.5-20140117.0.x86_64.qcow2): cloud-user
Fedora 19 (http://cloud.fedoraproject.org/fedora-19.x86_64.qcow2): fedora
Ubuntu 12.04 (http://cloud-images.ubuntu.com/precise/current/precise-server-cloudimg-amd64-disk1.img): ubuntu
