Great article. I have a few minor comments:
For Node 1:
1. There is a typo "the compute nade"
2. Point #5 - I think that packstack takes care of this.
3. In point #6 you do not need to do the quantum client. This is pulled 
in by openstack-quantum (it is required for the l3 agent)
4. The gedit is just to work around 
https://bugzilla.redhat.com/show_bug.cgi?id=889774 (you can solve this 
by setting an environment variable. I think that Martin has taken care 
of this so hopefully we can drop it from the doc soon. :)
5. For point 10 can you please add a note that the user must have 
sourced the keystonerc_admin first. This is essential as the quantum 
server script uses the environment variables to configure the keystone 
authentication.
6. For point 12 you have a typo "[DATABSE]". Please note that the 
quantum-server-setup creates a symbolic link for the plugin ini file. 
This can be seen at /etc/quantum/plugin.ini. The reason for doing this 
was to ensure that we can have generic startup script for the quantum 
service
7. Point 13 has a typo "that thy"
8. Point 15: This is on the host where the quantum service is running 
and the user does not need to run this. The nova conf was updated via 
the quantum-server-setup script
9. Regarding 15 - "/usr/bin/openstack-config --set|--del config_file 
section [parameter] [value]". That looks fishy and like a bug. I'll 
check it. You should remove that line from the doc
10. Point 22. The DHCP agent does not require the keystone settings. You 
can drop the following:
     auth_url = http://192.168.2.193:35357/v2.0/
     admin_username = quantum
     admin_password = Passw0rd
     admin_tenant_name = quantum
11. The l3 agent is required if you want to do the following:
     1. floating IP support
     2. enable the instances to get the meta data from the nova metadata 
service
For Node 2:
1. Point 8. Typo "[DATABASE}". Please note that the database does not 
used. The user does not need to update this. Point 7 ensured that the 
qpid hostname is correct that suffices.

Once again great doc.
Thanks
Gary
