+====================
+VMware in Kolla
+====================
+
+Overview
+========
+Kolla can deploy the Nova and Neutron Service(s) for VMware vSphere.
+Depending on the network architecture (NsxV or DVS) you choose, Kolla deploys
+the following OpenStack services for VMware vSphere:
+
+For VMware NsxV:
+
+* nova-compute
+* neutron-server
+
+For VMware DVS:
+
+* nova-compute
+* neutron-server
+* neutron-dhcp-agent
+* neutron-metadata-agent
+
+Kolla can deploy the Glance and Cinder services using VMware datastore as their
+backend. Ceilometer metering for vSphere is also supported.
+
+Because the `vmware-nsx <https://github.com/openstack/vmware-nsx>`__ drivers for
+neutron use completely different architecture than other types of virtualization,
+vmware-nsx drivers cannot coexist with other type of virtualization in one region.
+In neutron vmware-nsx drivers, neutron-server acts like an agent to translate
+OpenStack actions into what vSphere/NSX Manager API can understand.
+Neutron does not directly takes control of the Open vSwitch inside the VMware
+environment but through the API exposed by vSphere/NSX Manager.
+
+For VMware DVS, the Neutron DHCP agent does not attaches to Open vSwitch inside
+VMware environment, but attach to the Open vSwitch bridge called ``br-dvs`` on the
+OpenStack side and replies to/receives DHCP packets through VLAN. Similar to what the DHCP
+agent does, Neutron metadata agent attaches to ``br-dvs`` bridge and works through VLAN.
+
+.. note::
+
+    VMware NSX-DVS plugin does not support tenant networks, so all VMs should
+    attach to Provider VLAN/Flat networks.
+
+VMware NSX-V
+============
+
+Preparation
+-----------
+
+You should have a working NSX-V environment, this part is out of scope of Kolla.
+For more information, please see `VMware NSX-V documentation <https://docs.vmware.com/en/VMware-NSX-for-vSphere/>`__.
+
+.. note::
+
+    In addition, it is important to modify the firewall rule of vSphere to make
+    sure that VNC is accessible from outside VMware environment.
+
+    On every VMware host, edit /etc/vmware/firewall/vnc.xml as below:
+
+.. code-block:: console
+
+    <!-- FirewallRule for VNC Console -->
+    <ConfigRoot>
+    <service>
+    <id>VNC</id>
+    <rule id = '0000'>
+    <direction>inbound</direction>
+    <protocol>tcp</protocol>
+    <porttype>dst</porttype>
+    <port>
+    <begin>5900</begin>
+    <end>5999</end>
+    </port>
+    </rule>
+    <rule id = '0001'>
+    <direction>outbound</direction>
+    <protocol>tcp</protocol>
+    <porttype>dst</porttype>
+    <port>
+    <begin>0</begin>
+    <end>65535</end>
+    </port>
+    </rule>
+    <enabled>true</enabled>
+    <required>false</required>
+    </service>
+    </ConfigRoot>
+
+Then refresh the firewall config by:
+
+.. code-block:: console
+
+    esxcli network firewall refresh
+
+Verify that the firewall config is applied:
+
+.. code-block:: console
+
+    esxcli network firewall ruleset list
+
+Deployment
+----------
+
+Enable VMware nova-compute plugin and NSX-V neutron-server plugin in
+``/etc/kolla/globals.yml``:
+
+.. code-block:: console
+
+    nova_compute_virt_type: "vmware"
+    neutron_plugin_agent: "vmware_nsxv"
+
+.. note::
+
+    VMware NSX-V also supports Neutron FWaaS, LBaaS and VPNaaS services, you can enable
+    them by setting these options in globals.yml:
+
+    * enable_neutron_vpnaas: "yes"
+    * enable_neutron_lbaas: "yes"
+    * enable_neutron_fwaas: "yes"
+
+If you want to set VMware datastore as cinder backend, enable it in ``/etc/kolla/globals.yml``:
+
+.. code-block:: console
+
+    enable_cinder: "yes"
+    cinder_backend_vmwarevc_vmdk: "yes"
+    vmware_datastore_name: "TestDatastore"
+
+If you want to set VMware datastore as glance backend, enable it in ``/etc/kolla/globals.yml``:
+
+.. code-block:: console
+
+    glance_backend_vmware: "yes"
+    vmware_vcenter_name: "TestDatacenter"
+    vmware_datastore_name: "TestDatastore"
+
+VMware options are required in ``/etc/kolla/globals.yml``, these options should be
+configured correctly according to your NSX-V environment.
+
+Options for nova-compute and ceilometer:
+
+.. code-block:: console
+
+    vmware_vcenter_host_ip: "127.0.0.1"
+    vmware_vcenter_host_username: "admin"
+    vmware_vcenter_host_password: "admin"
+    vmware_vcenter_cluster_name: "cluster-1"
+    vmware_vcenter_insecure: "True"
+    vmware_vcenter_datastore_regex: ".*"
+
+Options for Neutron NSX-V support:
+
+.. code-block:: console
+
+    vmware_nsxv_user: "nsx_manager_user"
+    vmware_nsxv_password: "nsx_manager_password"
+    vmware_nsxv_manager_uri: "https://127.0.0.1"
+    vmware_nsxv_cluster_moid: "TestCluster"
+    vmware_nsxv_datacenter_moid: "TestDataCeter"
+    vmware_nsxv_resource_pool_id: "TestRSGroup"
+    vmware_nsxv_datastore_id: "TestDataStore"
+    vmware_nsxv_external_network: "TestDVSPort-Ext"
+    vmware_nsxv_vdn_scope_id: "TestVDNScope"
+    vmware_nsxv_dvs_id: "TestDVS"
+    vmware_nsxv_backup_edge_pool: "service:compact:1:2"
+    vmware_nsxv_spoofguard_enabled: "false"
+    vmware_nsxv_metadata_initializer: "false"
+    vmware_nsxv_edge_ha: "false"
+
+
+.. note::
+
+    If you want to set secure connections to VMware, set ``vmware_vcenter_insecure``
+    to false.
+    Secure connections to vCenter requires a CA file, copy the vCenter CA file to
+    ``/etc/kolla/config/vmware_ca``.
+
+
+Then you should start kolla-ansible deployment normally as KVM/QEMU deployment.
+
+
+VMware NSX-DVS
+==============
+
+Preparation
+-----------
+
+Before deployment, you should have a working VMware vSphere environment. Create a
+cluster and a vSphere Distributed Switch with all the host in the cluster attached
+to it.
+
+For more information, please see `Setting Up Networking with vSphere Distributed Switches <http://pubs.vmware.com/vsphere-51/index.jsp#com.vmware.vsphere.networking.doc/GUID-375B45C7-684C-4C51-BA3C-70E48DFABF04.html>`__.
+
+Deployment
+----------
+
+Enable VMware nova-compute plugin and NSX-V neutron-server plugin in ``/etc/kolla/globals.yml``:
+
+.. code-block:: console
+
+    nova_compute_virt_type: "vmware"
+    neutron_plugin_agent: "vmware_dvs"
+
+If you want to set VMware datastore as Cinder backend, enable it in ``/etc/kolla/globals.yml``:
+
+.. code-block:: console
+
+    enable_cinder: "yes"
+    cinder_backend_vmwarevc_vmdk: "yes"
+    vmware_datastore_name: "TestDatastore"
+
+If you want to set VMware datastore as Glance backend, enable it in ``/etc/kolla/globals.yml``:
+
+.. code-block:: console
+
+    glance_backend_vmware: "yes"
+    vmware_vcenter_name: "TestDatacenter"
+    vmware_datastore_name: "TestDatastore"
+
+VMware options are required in ``/etc/kolla/globals.yml``, these options should be
+configured correctly according to the vSphere environment you installed before.
+All option for nova, cinder, glance are the same as VMware-NSX, except the following
+options.
+
+Options for Neutron NSX-DVS support:
+
+.. code-block:: console
+
+    vmware_dvs_host_ip: "192.168.1.1"
+    vmware_dvs_host_port: "443"
+    vmware_dvs_host_username: "admin"
+    vmware_dvs_host_password: "password"
+    vmware_dvs_dvs_name: "VDS-1"
+    vmware_dvs_dhcp_override_mac: ""
+
+Then you should start kolla-ansible deployment normally as KVM/QEMU deployment.
