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.

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.

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:

PS C:\> $if = Get-NetIPAddress -IPAddress 192* | Get-NetIPInterface
PS C:\> New-VMSwitch -NetAdapterName $if.ifAlias -Name YOUR_BRIDGE_NAME -AllowManagementOS $false

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.

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:

enable_hyperv: "yes"

Hyper-V options are also required in /etc/kolla/globals.yml:

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:

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.

Add the Hyper-V node in ansible/inventory file:

[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:

pip install "pywinrm>=0.2.2"

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:

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:

PS C:\> Get-Service nova-compute
PS C:\> Get-Service neutron-hyperv-agent

PS C:\> Restart-Service nova-compute
PS C:\> Restart-Service neutron-hyperv-agent
