Nutanix の OVM を使用すると、Horizon Dashboard での「システム情報」には、デフォルトで登録されているサービス情報があります。必要なサービスは再起動時にまた登録されるので、不要そうなものはいったん削除してみます。
Horizon Dashboard「システム情報」の様子
デフォルトでは、「ovm」と「localhost.localdomain」というホストのサービスが登録されています。また、ovmctl でのセットアップの都合により不要なサービスが追加登録されます。
Compute Service
Block Storage Service
Network Service
Orchestration Service
「ハイパーバイザー」→「コンピュートホスト」の画面でも、ホスト（Acropolis Driver の OVM）が 3つ表示されます。
ちなみに今回の OVM は、こんな感じでセットアップしたものです。
サービス情報の削除
ためしに、削除してみます。
最初に、環境変数を読み込みます。
[root@ovm02 ~]# source keystonerc_admin [root@ovm02 ~(keystone_admin)]#
Compute Service（Nova）
Nova 関連のサービスを削除します。現状はこうなっています。
