This chapter describes the commands under the compute command.

18.1. compute agent create

Create compute agent. The compute agent functionality is hypervisor specific and is only supported by the XenAPI hypervisor driver. It was removed from nova in the 23.0.0 (Wallaby) release.

Usage:

openstack compute agent create [-h] [-f {json,shell,table,value,yaml}]
                                      [-c COLUMN] [--noindent]
                                      [--prefix PREFIX]
                                      [--max-width <integer>] [--fit-width]
                                      [--print-empty]
                                      <os> <architecture> <version> <url>
