heterogeneous, mixed with KVM environments. There is the vmware\_dvs
driver for Neutron ML2 plugin which provides usage Neutron for
networking in such environments. Thereby environments receives an
advanced network features:
- Ability to create multi-tier networks (e.g., web tier, db tier, app
tier).
- Control over IP addressing and security groups's rules.
- Ability to insert an configure their own services (e.g., firewall,

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 should appear
on the vCenter:
.. image:: _static/net04pg.png
.. raw:: latex
\pagebreak
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:
1. 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
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.

nova-networks. Unfortunately integration with VMware which realized in Fuel 6.1
and below doesn't provide the possibilities to using Neutron. It leads that an
environment which uses VMware hypervisors is greatly limited. When customers
There are several solutions which provide networking for OpenStack with
vSphere. Part of them are or were integrated in the Fuel: nova-network and
VMware NSXv plugin. Other part --- networking-vsphere -- is the separate
upstream project.
Unfortunately each of them has defects. Nova-network is the obsolete network
solution which provides really restricted possibilities. When customers

topologies:

* No generic service insertion.
Such we have the contradiction between customer needs and our solution.
This contradiction doesn't allow to use nova-network in big enterprise.
VMware NSXv and networking-vsphere don't have such restrictions. Both of this
solutions are based on the same idea: to create on ESXi's hosts special control
VMs and redirect all tenant traffic to them. That approach permits to using all
possibilities of Neutron but multiple traffic redirection dramatically affects
to network performance. Also NSXv can be used in VMware-only environments.

In that way no unnecessary traffic redirections and the given scheme admits to

#. DVS switches must be provisioned by using vCenter firstly and manually
#. All VDS'es must be provisioned by using vCenter firstly and manually.
#. There must be a mapping between physical network and DVS switch:
#. There must be a mapping between physical network and VDS'es:
3. VLANs will be used as a tenant network separation by KVMs OVS and ESXis
DVS (must be the same for tenant network regardless which switch type OVS
or DVS)
VDS (must be the same for tenant network regardless which switch type OVS
or VDS)
#. Each vSphere's Cluster has its own VDS.
#. There must be an ability to:
#. create / terminate network on DVS
#. create / terminate network on VDS
#. bind port on DVS to VM
#. bind port on VDS to VM
#. disable state of the neutron network / port on DVS
#. disable state of the neutron network / port on VDS
#. assign multiple vNIC to a single VM deployed on ESXi
#. add VM to security groups
5. Name of driver is vmware_dvs
Limitations:

#. Only VLANs are supported for tenant network separation (VxLAN support can
be added later, if project will be continued).

of using Neutron for networking are locked. Unfortunately current plugin's
architecture doesn't provide the way to pliable unlock it. Instead of it when
the plugin is installed it just amend the Nailgun's database and cancel this

installs and remotes the plugin after that he can deploy environment with
Neutron and VMware which will not work normally. User can care about that.
