Building a simple REST API server with libvirt and bottle

In this recipe, we are going to use all of the libvirt methods we saw in the earlier recipes to build a simple RESTfull API server, leveraging the bottle micro framework for Python.

Bottle is described as a fast and simple Web Server Gateway Interface (WSGI) micro web-framework for Python, which is distributed as a single module file.

Note

For more information on the bottle micro framework please visit the official website at: https://bottlepy.org/docs/dev/.

The simple API server we are implementing, will accept the following requests:

• list: get method that lists all defined libvirt instances.
• define: post method used to define a new KVM instance. We are going to provide the XML definition as a header in the post request.
• start: post method to start an instance. The name of the instance will be provided in the header of the request.
• stop: post method to spot a KVM instance.
• undefine: post method to delete the instance.
