Nova-HyperV in Kolla
|
|
====================
|
|
|
|
Overview
|
|
========
|
|
Currently, Kolla can deploy the following OpenStack services for Hyper-V:
|
|
|
|
* nova-compute
|
|
* neutron-hyperv-agent
|
|
* wsgate
|
|
|
|
It is possible to use Hyper-V as a compute node within an OpenStack Deployment.
|
|
The nova-compute service runs as openstack-compute, a 64-bit service directly
|
|
upon the Windows platform with the Hyper-V role enabled. The necessary Python
|
|
components as well as the nova-compute service are installed directly onto
|
|
the Windows platform. Windows Clustering Services are not needed for
|
|
functionality within the OpenStack infrastructure.
|
|
|
|
The wsgate is the FreeRDP-WebConnect service that is used for accessing
|
|
virtual machines from Horizon web interface.
|
|
|
|
.. note::
|
|
|
|
HyperV services are not currently deployed as containers. This functionality
|
|
is in development. The current implementation installs OpenStack services
|
|
via MSIs.
|
|
|
|
|
|
.. note::
|
|
|
|
HyperV services do not currently support outside the box upgrades. Manual
|
|
upgrades are required for this process. MSI release versions can be found
|
|
`here
|
|
<https://cloudbase.it/openstack-hyperv-driver/>`__.
|
|
To upgrade an existing MSI to a newer version, simply uninstall the current
|
|
MSI and install the newer one. This will not delete the configuration files.
|
|
To preserve the configuration files, check the Skip configuration checkbox
|
|
during installation.
|
|
|
|
|
|
Preparation for Hyper-V node
|
|
============================
|
|
|
|
Ansible communicates with Hyper-V host via WinRM protocol. An HTTPS WinRM
|
|
listener needs to be configured on the Hyper-V host, which can be easily
|
|
created with
|
|
`this PowerShell script
|
|
<https://github.com/ansible/ansible/blob/devel/examples/scripts/ConfigureRemotingForAnsible.ps1>`__.
|
|
|
|
|
|
A virtual switch has to be created with which Hyper-V virtual machines
|
|
communicate with OpenStack. To quickly enable an interface to be used as a
|
|
Virtual Interface the following PowerShell may be used:
|
|
|
|
.. code-block:: console
|
|
|
|
PS C:\> $if = Get-NetIPAddress -IPAddress 192* | Get-NetIPInterface
|
|
PS C:\> New-VMSwitch -NetAdapterName $if.ifAlias -Name YOUR_BRIDGE_NAME -AllowManagementOS $false
|
|
|
|
.. note::
|
|
|
|
It is very important to make sure that when you are using a Hyper-V node with only 1 NIC the
|
|
-AllowManagementOS option is set on True, otherwise you will lose connectivity to the Hyper-V node.
|
|
|
|
|
|
To prepare the Hyper-V node to be able to attach to volumes provided by
|
|
cinder you must first make sure the Windows iSCSI initiator service is
|
|
running and started automatically.
|
|
|
|
.. code-block:: console
|
|
|
|
PS C:\> Set-Service -Name MSiSCSI -StartupType Automatic
|
|
PS C:\> Start-Service MSiSCSI
|
|
|
|
|
|
|
|
Preparation for Kolla deployer node
|
|
===================================
|
|
|
|
Hyper-V role is required, enable it in ``/etc/kolla/globals.yml``:
|
|
|
|
.. code-block:: console
|
|
|
|
enable_hyperv: "yes"
|
|
|
|
Hyper-V options are also required in ``/etc/kolla/globals.yml``:
|
|
|
|
.. code-block:: console
|
|
|
|
hyperv_username: <HyperV username>
|
|
hyperv_password: <HyperV password>
|
|
vswitch_name: <HyperV virtual switch name>
|
|
nova_msi_url: "https://www.cloudbase.it/downloads/HyperVNovaCompute_Beta.msi"
|
|
|
|
If tenant networks are to be built using VLAN add corresponding type in
|
|
``/etc/kolla/globals.yml``:
|
|
|
|
.. code-block:: console
|
|
|
|
neutron_tenant_network_types: 'flat,vlan'
|
|
|
|
The virtual switch is the same one created on the HyperV setup part.
|
|
For nova_msi_url, different Nova MSI (Mitaka/Newton/Ocata) versions can
|
|
be found on `Cloudbase website
|
|
<https://cloudbase.it/openstack-hyperv-driver/>`__.
|
|
|
|
|
|
Add the Hyper-V node in ``ansible/inventory`` file:
|
|
|
|
.. code-block:: console
|
|
|
|
[hyperv]
|
|
<HyperV IP>
|
|
|
|
[hyperv:vars]
|
|
ansible_user=<HyperV user>
|
|
ansible_password=<HyperV password>
|
|
ansible_port=5986
|
|
ansible_connection=winrm
|
|
ansible_winrm_server_cert_validation=ignore
|
|
|
|
``pywinrm`` package needs to be installed in order for Ansible to work
|
|
on the HyperV node:
|
|
|
|
.. code-block:: console
|
|
|
|
pip install "pywinrm>=0.2.2"
|
|
|
|
.. note::
|
|
|
|
In case of a test deployment with controller and compute nodes as virtual machines
|
|
on Hyper-V, if VLAN tenant networking is used, trunk mode has to be enabled on the
|
|
VMs:
|
|
|
|
.. code-block:: console
|
|
|
|
Set-VMNetworkAdapterVlan -Trunk -AllowedVlanIdList <VLAN ID> -NativeVlanId 0 <VM name>
|
|
|
|
networking-hyperv mechanism driver is needed for neutron-server to
|
|
communicate with HyperV nova-compute. This can be built with source
|
|
images by default. Manually it can be intalled in neutron-server
|
|
container with pip:
|
|
|
|
.. code-block:: console
|
|
|
|
pip install "networking-hyperv>=4.0.0"
|
|
|
|
For neutron_extension_drivers, ``port_security`` and ``qos`` are
|
|
currently supported by the networking-hyperv mechanism driver.
|
|
By default only ``port_security`` is set.
|
|
|
|
|
|
Verify Operations
|
|
=================
|
|
|
|
OpenStack HyperV services can be inspected and managed from PowerShell:
|
|
|
|
.. code-block:: console
|
|
|
|
PS C:\> Get-Service nova-compute
|
|
PS C:\> Get-Service neutron-hyperv-agent
|
|
|
|
.. code-block:: console
|
|
|
|
PS C:\> Restart-Service nova-compute
|
|
PS C:\> Restart-Service neutron-hyperv-agent
|
|
|
|
|
|
