Manage Compute services

You can enable and disable Compute services. The following examples disable and enable the nova-compute service.

  1. List the Compute services:

    $ nova service-list
+------------------+----------+----------+---------+-------+----------------------------+-----------------+
| Binary           | Host     | Zone     | Status  | State | Updated_at                 | Disabled Reason |
+------------------+----------+----------+---------+-------+----------------------------+-----------------+
| nova-conductor   | devstack | internal | enabled | up    | 2013-10-16T00:56:08.000000 | None            |
| nova-cert        | devstack | internal | enabled | up    | 2013-10-16T00:56:09.000000 | None            |
| nova-compute     | devstack | nova     | enabled | up    | 2013-10-16T00:56:07.000000 | None            |

+------------------+----------+----------+---------+-------+----------------------------+-----------------+

  2. Disable a nova service:

    $ nova service-disable localhost.localdomain nova-compute --reason 'trial log'
+----------+--------------+----------+-------------------+
| Host     | Binary       | Status   | Disabled Reason   |
