# Overview
|
||||
|
||||
If you are developing your own plugin for Fuel, you will also need to prepare
|
||||
the documentation set, which includes Test Plan, Test Report and Plugin Guide.
|
||||
|
||||
<div id='id-section2'/>
|
||||
## How to use
|
||||
|
||||
This repo is organized as the doc tree with 2 main folders:
|
||||
- plugin guide
|
||||
- testing documentation
|
||||
- Test Plan
|
||||
- Test Report
|
||||
|
||||
To use these doc templates, follow these steps:
|
||||
|
||||
1. Clone the repo:
|
||||
|
||||
`git clone git@github.com:Mirantis/fuel-plugin-docs.git`
|
||||
|
||||
2. Populate the placeholders of the conf.py files (for Plugin Guide, Test
|
||||
Plan and Report) with plugin-specific information (e.g. document name,
|
||||
plugin release).
|
||||
|
||||
3. Populate the content of RST files which make up the document structure.
|
||||
|
||||
<div id='id-section3'/>
|
||||
|
||||
## How to build documentation
|
||||
|
||||
Once you're done with editing the conf.py and sample RST files, you should cd
|
||||
into the corresponding doc dir and run `make latexpdf`.
|
||||
|
||||
For example:
|
||||
```
|
||||
cd user_guide
|
||||
make latexpdf
|
||||
```
|
||||
|
||||
The PDF will be found in ./build subdir.
|
||||
|
||||
<div id='id-section4'/>
|
||||
|
||||
## Check yourself
|
||||
|
||||
Please use the checklists below to make sure you documentation
|
||||
meets the acceptance criteria.

### Plugin Guide
|
||||
|
||||
* The Plugin Guide contains plugin version in <fuel-plugin-name>-XX-XXX-X
|
||||
format.
|
||||
* The **Overview** section provides information on the following:
|
||||
|
||||
* high-level description of plugin functionality/use case
|
||||
* schemes (optional)
|
||||
|
||||
* The **Requirements** section provides information on the following:
|
||||
|
||||
* target MOS release (e.g. should be 8.0 not 8.0 and/or higher)
|
||||
* required compatible proprietary Partner product version
|
||||
* required compatible proprietary hw/software (if applicable)
|
||||
|
||||
* The **Prerequisites** section provides information on what should be done
|
||||
prior to the solution installation/configuration, specifically:
|
||||
|
||||
* List of required HW/SW and how to get it (where to order or how to
|
||||
download).
|
||||
* Compatible firmware versions (for HW) and software versions (for SW).
|
||||
* A link to official documentation and configuration guides of used HW/SH
|
||||
should be provided.
|
||||
* How to configure required external hardware/software (e.g. storage devices,
|
||||
switches and so on) so that user could use them via the the
|
||||
application/driver. A simple configuration would be enough.
|
||||
* If the solution can use specific HW/SW in several modes, then there should
|
||||
be instructions on how to properly configure the hw/software to use this
|
||||
very mode.
|
||||
|
||||
* The **Limitations** should outline the issues that might limit the plugin
|
||||
usage. Those can be:
|
||||
|
||||
* specific networking option available for the plugin (e.g. it can only use
|
||||
Neutron VXLAN)
|
||||
* known issues that might affect the plugin's operability (e.g. it's
|
||||
impossible to use non-ASCII characters)
|
||||
|
||||
* The **Release Notes** section should describe how this plugin version
|
||||
differs from the previous one.
|
||||
* The **Installing the plugin** section provides commands and estimated output.
|
||||
* The **Configuring the plugin** section provides the following information:
|
||||
|
||||
* It's clarified which MOS environment configuration should be used (how
|
||||
many controller, computes, which options/services should be enabled). All
|
||||
links to the official Mirantis OpenStack documentation are present. It's
|
||||
also okay to provide screenshots.
|
||||
* It's clarified how to configure MOS environment properly for the plugin
|
||||
usage (e.g. how to configure interfaces for different logical networks
|
||||
Fuel uses). It's also okay to provide screenshots.
|
||||
* If the plugin requires specific role/naming convention, then this is also
|
||||
outlined.
|
||||
* UI part of the plugin should have detailed description and instructions on
|
||||
where to get specific params. This should be done for every field and
|
||||
example values should be provided.
|
||||
* If the plugin supports several modes of usage, then there should be a flow
|
||||
for each mode (e.g. each mode should be presented as the step-by-step
|
||||
instruction with screenshots with all required UI elements listed in the
|
||||
correct order): e.g. select plugin checkbox, click a radio button, fill
|
||||
in the text fields.
|
||||
|
||||
* Network verification check is specified as the obligatory step prior to
|
||||
deployment. If it’s expected to fail, this fact should be explicitly stated
|
||||
and a reason should be provided.
|
||||
* The **User Guide** should contain:
|
||||
|
||||
* baseline commands (CLI reference) with the estimated output (e.g. create
|
||||
volumes, list volumes etc)
|
||||
* links to external documentation (e.g. if all baseline issues are covered
|
||||
in open source/proprietary documentation)
|
||||
|
||||
* The **Verification** section should explain how to verify that the plugin
|
||||
works as expected (CLI, expected output).
|
||||
* The **Troubleshooting** section should deliver specific guidance on:
|
||||
|
||||
* how to make sure that all services are running
|
||||
* how to check network connectivity (if needed)
|
||||
* logs (where to find those, what to pay attention to)

Troubleshooting
|
||||
+++++++++++++++
|
||||
|
||||
VMware dvs driver consists from two parts: the mechanism driver of neutron and
|
||||
the agent. Thereby the main source of information for troubleshooting is
|
||||
/var/log/neutron/server.log and /var/log/neutron/vmware-dvs-agent-....log.
|
||||
|
||||
Please to be sure in correctness of configuration in
|
||||
the /etc/neutron/neutron.conf, /etc/neutron/plugin.ini. and
|
||||
/etc/neutron/plugins/ml2/vmware_dvs-.....ini It should contain following
|
||||
values:
|
||||
|
||||
neutron.conf::
|
||||
|
||||
notification_driver=messagingv2
|
||||
|
||||
|
||||
plugin.ini::
|
||||
|

|
||||
|
||||
Sure all neutron-dvs-agent should be launched on corresponded nodes. On
|
||||
controllers --- under corosync and on compute-vmware --- via init script.
|
||||
|
||||
Also in case of trouble would be useful to check the
|
||||
connectivity between controller nodes and vCenter.

Using advanced neutron's possibilities with VMware DVS plugin
|
||||
-------------------------------------------------------------
|
||||
|
||||
#. Once OpenStack has been deployed, we can start using Neutron for
|
||||
networking. The port group for admin\_internal\_net could appear
|
||||
on the vCenter (don't worry if any DVS has missing portgroups):

2. In Horizon, the network topology should look like:
|
||||
|
||||
.. image:: _static/topology.png
|
||||
|
||||
where VMware is the name of the instance located on the vCenter.
|
||||
|
||||
#. You can use Neutron for such instance brand the same way as for KVM-located instances.
|
||||
|
||||
#. DVS Security groups functionality differs from KVM implementatin. VMWare DVS does not
|
||||
support stateful firewall properties and ICMP types. DVS Plugin realises emulation logic
|
||||
to support the similar behavior. It installs reverse traffic rule for each SG rule.
|
||||
VMWare DVS plugin state emulation logic uses ephemeral port range filter to rise security
|
||||
of reverse rules implementation.
|
||||
|
||||
Just add only those rules if you want to correctly launch EC2 compatible image with
|
||||
matadata request and DNS access:
|
||||
|
||||
Implement Custom TCP Egress rule to 169.254.169.254/32 CIDR port 80
|
||||
Implement Custom UDP Egress rule to '<DNS server IP or 0.0.0.0/0>' CIDR port 53
|
||||
|
||||
DVS plugin will install four rules:
|
||||

32768-65535 is the useful ethemetal port range for most Linux kernels and Windows hosts.
|
||||
|
||||
Common egress TCP rule looks like this:
|
||||
|
||||
TCP Egress to any ports 0.0.0.0/0 CIDR
|
||||
|
||||
It works like:
|
||||
|
||||
TCP Egress from any IP ports 32768-65535 to any IP any port
|
||||
TCP Ingress from any IP any port to any IP ports 32768-65535
|
||||
|
||||
and private ports of your VM like http or ssh will be closed.
|
||||
|
||||
DVS plugin support only symmectric ICMP interaction. If your host can ping destination host,
|
||||
it means the destination host can ping your host by reverse rules.
|
||||
|
||||
#. Sometimes the error at log files happens "Cannot complete operation due to concurrent
|
||||
modification by another operation." due to absence of concurrent access to modify resources
|
||||
by vSphere. Do not panic. Driver has special wrapper for this exception.

Introduction
|
||||
~~~~~~~~~~~~
|
||||
|
||||
The purpose of this document is to describe how to install, configure,
|
||||
and use the VMware DVS plugin 3.0.0 for Fuel 9.0.
|
||||
|
||||
Mirantis OpenStack supports using vCenter as a hypervisor on vCenter-only or
|
||||
heterogeneous environments that are mixed with KVM. The vmware_dvs driver for
|
||||
Neutron ML2 plugin allows using Neutron for networking in such environments.
|
||||
Therefore, you get the following advanced network features for your
|
||||
environment:
|
||||
|
||||
- Create multi-tier networks (for example: web tier, database tier,
|
||||
application tier)
|
||||
|
||||
- Control over IP addressing and security groups' rules.
|
||||
|
||||
- Add and configure custom services (for example: firewall,
|
||||
intrusion-prevention system)
|
||||
|
||||
- VPN/Bridge to a remote physical hosting or customer premises.

Troubleshooting
|
||||
~~~~~~~~~~~~~~~
|
||||
|
||||
VMware DVS driver consists of two parts: the mechanism driver of Neutron and
|
||||
the VMware DVS agent. Therefore, two main sources of information for
|
||||
troubleshooting are ``/var/log/neutron/server.log`` and
|
||||
``/var/log/neutron/vmware-dvs-agent-....log``.
|
||||
|
||||
**To verify Neutron configuration files:**
|
||||
|
||||
To deliver a stable performance of the VMware DVS plugin, verify that the
|
||||
Neutron configuration files contain the following values:
|
||||
|
||||
* ``/etc/neutron/neutron.conf``:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
notification_driver=messagingv2
|
||||
|
||||
* ``/etc/neutron/plugin.ini``:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[ml2]
|
||||
mechanism_drivers =openvswitch,l2population,vmware_dvs

||||

vsphere_password=<vsphere_password>
|
||||
|
||||
* ``/etc/neutron/plugins/ml2/vmware_dvs-<vcenter AZ>-<service name>.ini``:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[DEFAULT]
|
||||
host=<vcenter AZ>-<service name>
|
||||
|
||||
[securitygroup]
|
||||
enable_security_group = True
|
||||
firewall_driver=mech_vmware_dvs.agentDVS.vCenter_firewall.DVSFirewallDriver
|
||||
|
||||
[ml2_vmware]

|
||||
network_maps=physnet2:<VDS>
|
||||
vsphere_hostname=<vsphere_ip>
|
||||
vsphere_password=<vsphere_password>
|
||||
|
||||
Verify that all neutron-dvs-agent services are launched on corresponding nodes:
|
||||
|
||||
* On controllers: under corosync
|
||||
* On compute-vmware: using the init script
|
||||
|
||||
Verify the connectivity between controller nodes and vCenter:

Using advanced Neutron possibilities with VMware DVS plugin
|
||||
-----------------------------------------------------------
|
||||
|
||||
This section describes the features that you get while using the VMware DVS
|
||||
plugin as well as outlines the usage aspects of DVS security groups.
|
||||
|
||||
Once you deploy an OpenStack environment with VMware DVS plugin, you can
|
||||
start using Neutron for networking.
|
||||
|
||||
The port group for ``admin_internal_net`` is created on clusters when VMs
|
||||
are attached:

||||

||||

|

||||
In Horizon, the network topology looks like the following:
|
||||
|
||||
.. figure:: _static/topology.png
|
||||
:width: 100%
|
||||
|
||||
where *VMware* is the name of the instance located in vCenter. You can use
|
||||
Neutron for such instance the same way as for KVM-located instances.
|
||||
|
||||
.. TODO OL: Update the picture so that it displays the instance name
|
||||
as mentioned in description.
|
||||
|
||||
**DVS security groups**
|
||||
|
||||
The functionality of the VMWare DVS plugin security groups differs from the
|
||||
KVM implementation:
|
||||
|
||||
* The VMWare DVS plugin does not support stateful firewall properties and
|
||||
ICMP types. It realizes the emulation logic to support similar
|
||||
behavior. The plugin installs a reverse traffic rule for each security group
|
||||
rule.
|
||||
* The VMWare DVS plugin state emulation logic uses ephemeral port range filter
|
||||
to rise the security of reverse rules implementation.
|
||||
|
||||
You can only add the reverse rules to correctly launch an EC2-compatible
|
||||
image with metadata request and DNS access.
|
||||
|
||||
**To add reverse rules:**
|
||||
|
||||
#. Implement a custom TCP egress rule to 169.254.169.254//32 CIDR port 80.
|
||||
#. Implement a custom UDP egress rule to <DNS server IP or 0.0.0.0//0>
|
||||
CIDR port 53.
|
||||
|
||||
The VMWare DVS plugin installs four rules:
|
||||
|
||||
#. TCP egress from any IP ports 32768-65535 to metadata IP port 80
|
||||
|
||||
#. TCP ingress from metadata IP port 80 to any IP ports 32768-65535
|
||||
|
||||
#. UDP egress from any IP ports 32768-65535 to DNS IP port 53
|
||||
|
||||
#. UDP ingress from DNS IP port 53 to any IP ports 32768-65535
|
||||
|
||||
.. note:: 32768-65535 is a useful ephemeral port range for most Linux kernels
|
||||
and Windows hosts.
|
||||
|
||||
Example of a common egress TCP rule:
|
||||
|
||||
* TCP egress to any ports 0.0.0.0/0 CIDR
|
||||
|
||||
It works in the following way:
|
||||
|
||||
* TCP egress from any IP ports 32768-65535 to any IP any port
|
||||
* TCP ingress from any IP any port to any IP ports 32768-65535
|
||||
|
||||
Once applied, the private ports of your VM like HTTP or SSH will be closed.
|
||||
|
||||
The VMWare DVS plugin supports only symmetric ICMP interaction. If your host
|
||||
can ping a destination host, it means that the destination host can ping your
|
||||
host by reverse rules.
|
||||
|
||||
Sometimes, you can see the following error in log files:
|
||||
*Cannot complete operation due to concurrent modification by another
|
||||
operation.*
|
||||
Reason: concurrent access is missing to modify resources by vSphere.
|
||||
Solution: the VMWare DVS plugin driver has special wrapper for this exception.
|
||||
Therefore, you can ignore this error.
