1.2.4. OpenStack support

One of the services provided by OpenStack Nova is to create the virtual ports of the VMs so OpenStack Neutron can build the proper networking services toward these VMs. Virtual Accelerator’s virtual port support relies on the vhost-user feature, which is not natively supported by OpenStack yet. Therefore, 6WIND has built an extension for Nova that enables the use of QEMU’s and libvirt’s vhost-user capabilities.

To enable vhost-user in Nova (up to Queens release):

1. Install or update the 6WIND OpenStack plugin on the compute nodes:

   # yum install -y 6wind-openstack-extensions
   

Note

OpenStack has to be installed before installing Virtual Accelerator and this extension.

Note

After OpenStack Queens, 6WIND neutron plugins have replaced this 6wind-openstack-extensions package.
