OpenStack Hypervisor

This snap is designed to be used with a deployed OpenStack Control plane such as delivered by Sunbeam.

Getting Started

To get started with the OpenStack Hypervisor, install the snap using snapd:

$ sudo snap install openstack-hypervisor

The snap needs to be configured with credentials and URL's for the Identity service of the OpenStack cloud that it will form part of - for example:

$ sudo snap set openstack-hypervisor \
    identity.auth_url= \
    identity.username=nova-hypervisor-01 \

it's also possible to configure domain and project configuration.

The snap also needs to be configured with access to RabbitMQ:

$ sudo snap set openstack-hypervisor \

and with URL's for access to Network services:

$ sudo snap set openstack-hypervisor \

The snap has numerous other configuration options - see "Configuration Reference" for full details.
