For VMware vCenter integration,
the nova-compute service (with VCDriver configured) runs on the Controller node.
**Procedure:**
Beginning with Fuel 6.1, the *Storage - Cinder Proxy to VMware Datastore* role
is introduced. It will deploy Cinder with VMDK backend:
that means, the new role provides block storage for VMs that are running on VMware vCenter.
The already known *Storage - Cinder* role can be enabled for Cinder with LVM or Ceph.
#. In the configuration screen, select the `Nodes` tab.
#. Assign a role to the node server by checking the required option from
the available options list:

* - Role
- Description
* - **Controller**
- Controller node initiates orchestration activities and provides
an external API. Fuel installs components such as Glance, Keystone,
Horizon, and Nova-Scheduler on Controller node as well.
| By default, for VMware vCenter integration, a nova-compute service
with VCDriver runs on Controller node.
The nova-compute service on Controller node manages VMs running
on ESXi hosts through vCenter.
* - **Compute**
- Compute node creates, manages, and terminates VMs.
The nova-compute service on Compute node manages locally running
VMs through KVM/QEMU.
* - **Storage - Cinder**
- Cinder node provides scheduling of block storage resources,
typically delivered over iSCSI or other compatible backend
storage systems. You can use Block storage for database storage,
expandable file systems, or to provide a server with access
to raw block level devices. This node role can be enabled for
the Cinder with LVM or Ceph environment.
* - **Storage - Cinder Proxy to VMware Datastore**
- Cinder-VMware provides scheduling of block storage resources delivered
over VMware vCenter.
* - **Compute VMware**
- Compute VMware node runs nova-compute with VCDriver that manages
ESXI computing resources through VMware vCenter. It enables you to deploy
a nova-compute service on a standalone node rather than Controller
node.
Deploy nova-compute on a standalone node
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If you need to distribute nova-compute services among available nodes
and deploy nova-compute on a standalone node, proceed with the
following steps.
**Procedure**:
#. Assign a *Compute VMware* role to the node.
#. In the *VMware tab* for a specific cluster, select this node
as the *Target node* for the ``nova-compute`` service.
.. note::
Known limitations for the *Compute VMware* node role:
* you cannot combine it with any other role;
* you cannot add a Compute-VMware node to a deployed OpenStack environment.

* :ref:`nova_computes` configuration.

Beginning with Fuel 6.1,

For each vSphere cluster,
you need to configure separate nova-compute service that will be running on the Controller node.
Each nova-compute service controls a single vSphere cluster.
For each vSphere cluster, you need to configure a separate nova-compute
service that will be running either on the Controller node,
or on a Compute-VMware host.
The following options are available:
Select from the following options:
#. for vCenter only environment, do not add any compute nodes.
* for vCenter only environment - do not add any compute nodes.
#. for dual hypervisors support (KVM or QEMU with vCenter),
you should do the following:
after selecting vCenter checkbox in the Fuel UI wizard, specify vCenter settings (host or IP),
username, password and which clusters you want to use.
* for dual hypervisors environments - configure the following:
* The cluster name is used to specify the cluster you would like
to use for OpenStack.
* **vSphere cluster** - specifies the name of the cluster that this nova-compute
service manages.
* Service name is the name that will be used to reference to your cluster in OpenStack.
Usually, you can copy cluster name from the field above,
but if the cluster name contains non-ASCII characters,
you must provide valid service name for it
(string that contains numbers, letters (a-z) and
underscore).
* **Service name** - specifies the service name to reference to your cluster.
It is a string that should not contain any non-ASCII characters.
* Datastore regexp is used
to indicate data stores to use with Compute.
For example, if you add *nas.*, all data stores that have a name starting
with "nas" will be chosen.
If you plan to use all available datastores, leave the field blank.
In this case, nova-compute service will pick the first data store returned by the vSphere API.
To learn more about
this setting, see
`VMware vSphere <http://docs.openstack.org/juno/config-reference/content/vmware.html>`_ guide.
* **Datastore regexp** - indicates datastores to use with Compute.
For example, if you select `openstack-.*`, all datastores that have
a name starting with `openstack-` are chosen.
