Add v2 API support for the Cisco plugin

Blueprint cisco-plugin-v2-api-support

New meta-plugin which makes use of the Quantum db_plugin and supports
the new v2 API
Changes to the Cisco DB model, now reusing quantum DB for core attributes
Changes to the device sub plugins to access the quantum DB for core
resources' state versus Cisco DB
Addition of fake/dummy drivers to support testing of the device sub
plugins even without actual hardware
New v2 unit tests which exercise the meta-plugin and the device sub
-plugins as well
In general creating new v2 modules such that v1.x code can be deprecated
easily by deleting the older modules. The following files are v2
versions of older modules, only the imports have changed, most of the
other code is the same as from the older modules (already reviewed):
quantum/plugins/cisco/common/cisco_credentials_v2.py
quantum/plugins/cisco/db/network_db_v2.py
quantum/plugins/cisco/db/network_models_v2.py
quantum/plugins/cisco/db/nexus_db_v2.py
quantum/plugins/cisco/db/nexus_models_v2.py

quantum/plugins/cisco/ucs/cisco_ucs_inventory_v2.py
quantum/plugins/cisco/ucs/cisco_ucs_plugin_v2.py
quantum/plugins/cisco/segmentation/l2network_vlan_mgr_v2.py

All changes are contained with the Cisco plugin.

README: A Quantum Plugin Framework for Supporting L2 Networks Spannning Multiple Switches
README for Quantum v2.0:
A Plugin Framework for Supporting Quantum Networks Spannning Multiple Switches
=========================================================================================
Introduction
------------
This plugin implementation provides the following capabilities:
* A reference implementation for a Quantum Plugin Framework
(For details see: http://wiki.openstack.org/quantum-multi-switch-plugin)
* Supports multiple switches in the network
* Supports multiple models of switches concurrently
* Supports use of multiple L2 technologies
* Supports the Cisco Nexus family of switches.
* Supports Cisco UCS blade servers with M81KR Virtual Interface Cards
(aka "Palo adapters") via 802.1Qbh.
Pre-requisites
--------------
(The following are necessary only when using the UCS and/or Nexus devices in your system.
If you plan to just leverage the plugin framework, you do not need these.)
If you are using a Nexus switch in your topology, you'll need the following
NX-OS version and packages to enable Nexus support:
* NX-OS 5.2.1 (Delhi) Build 69 or above.
* paramiko library - SSHv2 protocol library for python
* ncclient v0.3.1 - Python library for NETCONF clients
** You need a version of ncclient modifed by Cisco Systems.
To get it, from your shell prompt do:
git clone git@github.com:CiscoSystems/ncclient.git
sudo python ./setup.py install
** For more information of ncclient, see:
http://schmizz.net/ncclient/
* One or more UCS B200 series blade servers with M81KR VIC (aka
Palo adapters) installed.
* UCSM 2.0 (Capitola) Build 230 or above.
* OS supported:
** RHEL 6.1 or above
** Ubuntu 11.10 or above
** Package: python-configobj-4.6.0-3.el6.noarch (or newer)
** Package: python-routes-1.12.3-2.el6.noarch (or newer)
** Package: pip install mysql-python
Module Structure:

Plugin Installation Instructions
----------------------------------
1. Make a backup copy of quantum/etc/quantum.conf
2. Edit quantum/etc/quantum.conf and edit the "core_plugin" for v2 API
core_plugin = quantum.plugins.cisco.network_plugin.PluginV2
3. MySQL database setup:
3a. Create quantum_l2network database in mysql with the following command -
mysql -u<mysqlusername> -p<mysqlpassword> -e "create database quantum_l2network"
3b. Enter the quantum_l2network database configuration info in the
quantum/plugins/cisco/conf/db_conn.ini file.
4. If you want to turn on support for Cisco Nexus switches:
4a. Uncomment the nexus_plugin property in
etc/quantum/plugins/cisco/cisco_plugins.ini to read:
[PLUGINS]
nexus_plugin=quantum.plugins.cisco.nexus.cisco_nexus_plugin_v2.NexusPlugin
4b. Enter the relevant configuration in the
etc/quantum/plugins/cisco/nexus.ini file. Example:
[SWITCH]
# Change the following to reflect the IP address of the Nexus switch.
# This will be the address at which Quantum sends and receives configuration
# information via SSHv2.
nexus_ip_address=10.0.0.1
# Port numbers on the Nexus switch to each one of the UCSM 6120s is connected
# Use shortened interface syntax, e.g. "1/10" not "Ethernet1/10".
nexus_first_port=1/10
nexus_second_port=1/11
#Port number where SSH will be running on the Nexus switch. Typically this is 22
#unless you've configured your switch otherwise.
nexus_ssh_port=22
[DRIVER]
name=quantum.plugins.cisco.nexus.cisco_nexus_network_driver.CiscoNEXUSDriver
4c. Make sure that SSH host key of the Nexus switch is known to the
host on which you are running the Quantum service. You can do
this simply by logging in to your Quantum host as the user that
Quantum runs as and SSHing to the switch at least once. If the
host key changes (e.g. due to replacement of the supervisor or
clearing of the SSH config on the switch), you may need to repeat
this step and remove the old hostkey from ~/.ssh/known_hosts.
5. If your are using UCS blade servers with M81KR Virtual Interface Cards and
want to leverage the VM-FEX features,
5a. Uncomment the ucs_plugin propertes in
etc/quantum/plugins/cisco/cisco_plugins.ini to read:
[PLUGINS]
ucs_plugin=quantum.plugins.cisco.ucs.cisco_ucs_plugin_v2.UCSVICPlugin
[INVENTORY]
ucs_plugin=quantum.plugins.cisco.ucs.cisco_ucs_inventory_v2.UCSInventory
5b. Enter the relevant configuration in the
etc/quantum/plugins/cisco/ucs.ini file. Example:
[UCSM]
#change the following to the appropriate UCSM IP address
#if you have more than one UCSM, enter info from any one
ip_address=<put_ucsm_ip_address_here>
default_vlan_name=default
default_vlan_id=1
max_ucsm_port_profiles=1024
profile_name_prefix=q-
[DRIVER]
name=quantum.plugins.cisco.ucs.cisco_ucs_network_driver.CiscoUCSMDriver
5c. Configure the UCS systems' information in your deployment by editing the
quantum/plugins/cisco/conf/ucs_inventory.ini file. You can configure multiple
UCSMs per deployment, multiple chassis per UCSM, and multiple blades per
chassis. Chassis ID and blade ID can be obtained from the UCSM (they will
typically be numbers like 1, 2, 3, etc.). Also make sure that you put the exact
hostname as nova sees it (the host column in the services table of the nova
DB will give you that information).
[ucsm-1]
ip_address = <put_ucsm_ip_address_here>
[[chassis-1]]
chassis_id = <put_the_chassis_id_here>
[[[blade-1]]]
blade_id = <put_blade_id_here>
host_name = <put_hostname_here>
[[[blade-2]]]
blade_id = <put_blade_id_here>
host_name = <put_hostname_here>
[[[blade-3]]]
blade_id = <put_blade_id_here>
host_name = <put_hostname_here>
[ucsm-2]
ip_address = <put_ucsm_ip_address_here>
[[chassis-1]]
chassis_id = <put_the_chassis_id_here>
[[[blade-1]]]
blade_id = <put_blade_id_here>
host_name = <put_hostname_here>
[[[blade-2]]]
blade_id = <put_blade_id_here>
host_name = <put_hostname_here>
5d. Configure your OpenStack installation to use the 802.1qbh VIF driver and
Quantum-aware scheduler by editing the /etc/nova/nova.conf file with the
following entries:
scheduler_driver=quantum.plugins.cisco.nova.quantum_port_aware_scheduler.QuantumPortAwareScheduler
quantum_host=127.0.0.1
quantum_port=9696
libvirt_vif_driver=quantum.plugins.cisco.nova.vifdirect.Libvirt802dot1QbhDriver
libvirt_vif_type=802.1Qbh
Note: To be able to bring up a VM on a UCS blade, you should first create a
port for that VM using the Quantum create port API. VM creation will
fail if an unused port is not available. If you have configured your
Nova project with more than one network, Nova will attempt to instantiate
the VM with one network interface (VIF) per configured network. To provide
plugin points for each of these VIFs, you will need to create multiple
Quantum ports, one for each of the networks, prior to starting the VM.
However, in this case you will need to use the Cisco multiport extension
API instead of the Quantum create port API. More details on using the
multiport extension follow in the section on multi NIC support.
To support the above configuration, you will need some Quantum modules. It's easiest
to copy the entire quantum directory from your quantum installation into:
/usr/lib/python2.7/site-packages/
This needs to be done on each nova compute node.
7. Verify that you have the correct credentials for each IP address listed
in quantum/plugins/cisco/conf/credentials.ini. Example:
# Provide the UCSM credentials, create a separte entry for each UCSM used in your system
# UCSM IP address, username and password.
[10.0.0.2]
username=admin
password=mySecretPasswordForUCSM
# Provide the Nexus credentials, if you are using Nexus switches.
# If not this will be ignored.
[10.0.0.1]
username=admin
password=mySecretPasswordForNexus
In general, make sure that every UCSM and Nexus switch used in your system,
has a credential entry in the above file. This is required for the system to
be able to communicate with those switches.
9. Start the Quantum service. If something doesn't work, verify the
your configuration of each of the above files.
Multi NIC support for VMs
-------------------------
As indicated earlier, if your Nova setup has a project with more than one network,
Nova will try to create a virtual network interface (VIF) on the VM for each of those
networks. Before each VM is instantiated, you should create Quantum ports on each of
those networks. These ports need to be created using the following rest call:
POST /1.0/extensions/csco/tenants/{tenant_id}/multiport/
with request body:
{'multiport':
{'status': 'ACTIVE',
'net_id_list': net_id_list,
'ports_desc': {'key': 'value'}}}
where,
net_id_list is a list of network IDs: [netid1, netid2, ...]. The "ports_desc" dictionary
is reserved for later use. For now, the same structure in terms of the dictionary name, key
and value should be used.
The corresponding CLI for this operation is as follows:
PYTHONPATH=. python quantum/plugins/cisco/client/cli.py create_multiport <tenant_id> <net_id1,net_id2,...>
(Note that you should not be using the create port core API in the above case.)
How to test the installation
----------------------------
The unit tests are located at quantum/plugins/cisco/tests/unit/v2. They can be
executed from the top level Quantum directory using the run_tests.sh script.
1. Testing the core API (without UCS/Nexus/RHEL device sub-plugins configured):
By default all the device sub-plugins are disabled (commented out) in
etc/quantum/plugins/cisco/cisco_plugins.ini
./run_tests.sh quantum.plugins.cisco.tests.unit.v2.test_api_v2
./run_tests.sh quantum.plugins.cisco.tests.unit.v2.test_network_plugin
2. For testing the Nexus device sub-plugin perform the following configuration:
Edit etc/quantum/plugins/cisco/cisco_plugins.ini to add:
In the [PLUGINS] section add:
nexus_plugin=quantum.plugins.cisco.nexus.cisco_nexus_plugin_v2.NexusPlugin
Edit the etc/quantum/plugins/cisco/nexus.ini file.
When not using Nexus hardware use the following dummy configuration verbatim:
[SWITCH]
nexus_ip_address=1.1.1.1
nexus_first_port=1/10
nexus_second_port=1/11
nexus_ssh_port=22
[DRIVER]
name=quantum.plugins.cisco.tests.unit.v2.nexus.fake_nexus_driver.CiscoNEXUSFakeDriver
Or when using Nexus hardware (put the values relevant to your setup):
[SWITCH]
nexus_ip_address=1.1.1.1
nexus_first_port=1/10
nexus_second_port=1/11
nexus_ssh_port=22
[DRIVER]
name=quantum.plugins.cisco.nexus.cisco_nexus_network_driver.CiscoNEXUSDriver
(Note: Make sure that quantum/plugins/cisco/conf/credentials.ini has an entry for
the nexus_ip_address being used in the above cases)
3. For testing the UCS device sub-plugin perform the following configuration:
Edit etc/quantum/plugins/cisco/cisco_plugins.ini to add:
In the [PLUGINS] section add:
ucs_plugin=quantum.plugins.cisco.ucs.cisco_ucs_plugin_v2.UCSVICPlugin
In the [INVENTORY] section add:
When not using UCS hardware:
ucs_plugin=quantum.plugins.cisco.tests.unit.v2.ucs.cisco_ucs_inventory_fake.UCSInventory
Or when using UCS hardware:
ucs_plugin=quantum.plugins.cisco.ucs.cisco_ucs_inventory_v2.UCSInventory
Edit the etc/quantum/plugins/cisco/ucs.ini file.
When not using UCS hardware:
[DRIVER]
name=quantum.plugins.cisco.tests.unit.v2.ucs.fake_ucs_driver.CiscoUCSMFakeDriver
Or when using UCS hardware:
[DRIVER]
name=quantum.plugins.cisco.ucs.cisco_ucs_network_driver.CiscoUCSMDriver
