Nutanix CE + OpenStack Service VM（OVM）を、Remote OpenStack Controller を使用する「OVM-services」で構成してみます。
今回の構成
Ravello を使用しています。
OVM#1 / #2 は、Nutanix CE とは独立した VM にしています。
OpenStack Controller もとりあえず Acropolis OVM を使用してみました。
Acropolis OVM#1
- ホスト名： ovm01
- IP アドレス： 10.1.1.15/24
OpenStack Controller ※Acropolis OVM#2
- ホスト名： ovm02
- IP アドレス： 10.1.1.16/24
Nutanix CE クラスタ
- クラスタ名： ntnx-ce
- IP アドレス： 10.1.1.12 ※クラスタ VIP
- バージョン： 2016.03.13
Ravello の VM は、以前の投稿と同様の構成にしています。
ただし、Nutanix CE は IP アドレスが /24 のものを用意しました。
参考資料
主に、下記を参考にしました。

1. Nutanix CE Cluster のセットアップ
今回は、Nutanix CE のシングルノードクラスタを構成済みです。
Prism にログインして、Nutanix クラスタの設定をしておきます。
クラスタ名と VIP を設定します。
「default」という名前のストレージ コンテナを作成します。
「Storage」→「＋ Container」で、
「default」コンテナを作成しておきます。
2. Acropolis OVM の初期設定
今回も Ravello を使用しているので、まずコンソール経由で初期設定をします。
OVM#1 と OVM#2 両方で、 SSH で接続できるようにネットワーク設定をします。
OVM#1
[root@none ~]# ip addr add 10.1.1.15/24 dev eth0 [root@none ~]# ip route add default via 10.1.1.1
OVM#2
[root@none ~]# ip addr add 10.1.1.16/24 dev eth0 [root@none ~]# ip route add default via 10.1.1.1
ついでに root パスワードも変更しておきます。
[root@none ~]# passwd Changing password for user root. New password: Retype new password: passwd: all authentication tokens updated successfully.
3. OpenStack Controller（Acropolis OVM#2） のセットアップ
OVM#2 を、OpenStack Controller としてセットアップします。
Acropolis Driver を追加（ovmctl --add ovm）します。
[root@none ~]# ovmctl --add ovm --name ovm02 --ip 10.1.1.16 --netmask 255.255.255.0 --gateway 10.1.1.1 --nameserver 10.1.1.1 --domain ntnx.local 1/2: Remove default JSON: Successful 2/2: Add service JSON: Restarting network (via systemctl): [ OK ] Successful [root@none ~]#
そして、OpenStack Controller としてセットアップします。
※「--add ovm」でホスト名も設定されるので、ログインしなおすとプロンプトがホスト名になります。
[root@ovm02 ~]# ovmctl --add controller --name ovm02 --ip 10.1.1.16 1/4: Stop services: Redirecting to /bin/systemctl stop openstack-nova-api.service Redirecting to /bin/systemctl stop openstack-nova-consoleauth.service Redirecting to /bin/systemctl stop openstack-nova-scheduler.service Redirecting to /bin/systemctl stop openstack-nova-conductor.service Redirecting to /bin/systemctl stop openstack-nova-compute.service Redirecting to /bin/systemctl stop openstack-nova-cert.service Redirecting to /bin/systemctl stop openstack-nova-novncproxy.service Redirecting to /bin/systemctl stop openstack-cinder-api.service Redirecting to /bin/systemctl stop openstack-cinder-scheduler.service Redirecting to /bin/systemctl stop openstack-cinder-volume.service Redirecting to /bin/systemctl stop openstack-cinder-backup.service Redirecting to /bin/systemctl stop openstack-glance-registry.service Redirecting to /bin/systemctl stop openstack-glance-api.service Redirecting to /bin/systemctl stop neutron-dhcp-agent.service Redirecting to /bin/systemctl stop neutron-l3-agent.service Redirecting to /bin/systemctl stop neutron-metadata-agent.service Redirecting to /bin/systemctl stop neutron-openvswitch-agent.service Redirecting to /bin/systemctl stop neutron-server.service Redirecting to /bin/systemctl start iptables.service Note: Forwarding request to 'systemctl enable iptables.service'.

5. OpenStack Controller（OVM#2）でのサービス設定修正
OVM#2 でエンドポイントやサービス起動設定の修正をします。
/root/keystonerc_admin ファイルに、環境変数が記載されています。
[root@ovm02 ~]# cat keystonerc_admin unset OS_SERVICE_TOKEN export OS_USERNAME=admin export OS_PASSWORD=admin export OS_AUTH_URL=http://127.0.0.1:5000/v2.0 export PS1='[\u@\h \W(keystone_admin)]\$ ' export OS_TENANT_NAME=admin export OS_REGION_NAME=RegionOne
これを source コマンドで読み込んでから OpenStack 関連のコマンドを実行します。
[root@ovm02 ~]# source keystonerc_admin [root@ovm02 ~(keystone_admin)]#
Glance Endpoint 切り替え
Glance のエンドポイントを OVM#1 のアドレスに変更します。
現状のエンドポイントです。
[root@ovm02 ~(keystone_admin)]# openstack endpoint show glance +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | adminurl | http://10.1.1.16:9292 | | enabled | True | | id | 124ff05099484f5991302cedf30ba897 | | internalurl | http://10.1.1.16:9292 | | publicurl | http://10.1.1.16:9292 | | region | RegionOne | | service_id | 7064377731d7458b8abd4357ced971a5 | | service_name | glance | | service_type | image | +--------------+----------------------------------+
エンドポイントを削除して、OVM#1 のアドレスで作成しなおします。

Neutron Endpoint 切り替え
Neutron のエンドポイントを OVM#1 のアドレスに変更します。
現状のエンドポイントです。
[root@ovm02 ~(keystone_admin)]# openstack endpoint show neutron +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | adminurl | http://10.1.1.16:9696 | | enabled | True | | id | d4fc610a6d2545649b9290e50d6c4980 | | internalurl | http://10.1.1.16:9696 | | publicurl | http://10.1.1.16:9696 | | region | RegionOne | | service_id | e9abbc67c14a4acdab46166b59799212 | | service_name | neutron | | service_type | network | +--------------+----------------------------------+
エンドポイントを削除して、OVM#1 のアドレスで作成しなおします。
[root@ovm02 ~(keystone_admin)]# openstack endpoint delete d4fc610a6d2545649b9290e50d6c4980 [root@ovm02 ~(keystone_admin)]# openstack endpoint create \ > --publicurl http://10.1.1.15:9696 \ > --adminurl http://10.1.1.15:9696 \ > --internalurl http://10.1.1.15:9696 \ > --region RegionOne \ > e9abbc67c14a4acdab46166b59799212 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | adminurl | http://10.1.1.15:9696 | | id | d2cee20010964addb536934ec5a73479 | | internalurl | http://10.1.1.15:9696 | | publicurl | http://10.1.1.15:9696 | | region | RegionOne | | service_id | e9abbc67c14a4acdab46166b59799212 | | service_name | neutron | | service_type | network | +--------------+----------------------------------+
Nova 設定修正
/etc/nova/nova.conf ファイルを編集して、Glance ホストのアドレスを OVM#1 に設定します。
[root@ovm02 ~]# openstack-config --set /etc/nova/nova.conf glance host 10.1.1.15 [root@ovm02 ~]# openstack-config --set /etc/nova/nova.conf glance port 9292 [root@ovm02 ~]# openstack-config --set /etc/nova/nova.conf glance api_servers '$host:$port'
openstack-nova-compute サービスは Controller では不要なので停止します。
[root@ovm02 ~]# systemctl disable openstack-nova-compute.service [root@ovm02 ~]# systemctl stop openstack-nova-compute.service
Cinder 設定修正
/etc/cinder/cinder.conf ファイルを編集して、Glance ホストのアドレスを OVM#1 に設定します。
[root@ovm02 ~]# openstack-config --set /etc/cinder/cinder.conf DEFAULT glance_host 10.1.1.15 [root@ovm02 ~]# openstack-config --set /etc/cinder/cinder.conf DEFAULT glance_port 9292 [root@ovm02 ~]# openstack-config --set /etc/cinder/cinder.conf DEFAULT glance_api_servers '$glance_host:$glance_port'
LVM バックエンドの設定を削除します。
[root@ovm02 ~]# openstack-config --del /etc/cinder/cinder.conf lvm
openstack-cinder-volume サービスを停止します。
[root@ovm02 ~]# systemctl disable openstack-cinder-volume.service [root@ovm02 ~]# systemctl stop openstack-cinder-volume.service
Glance サービスの停止
openstack-glance-api サービスを停止します。
[root@ovm02 ~]# systemctl disable openstack-glance-api.service Removed symlink /etc/systemd/system/multi-user.target.wants/openstack-glance-api.service. [root@ovm02 ~]# systemctl stop openstack-glance-api.service
openstack-glance-registry サービスを停止します
[root@ovm02 ~]# systemctl disable openstack-glance-registry.service Removed symlink /etc/systemd/system/multi-user.target.wants/openstack-glance-registry.service. [root@ovm02 ~]# systemctl stop openstack-glance-registry.service
6. サービスの再起動
nova-compute 以外の Nova サービスを再起動します。
[root@ovm02 ~]# systemctl restart openstack-nova-api.service [root@ovm02 ~]# systemctl restart openstack-nova-consoleauth.service [root@ovm02 ~]# systemctl restart openstack-nova-scheduler.service [root@ovm02 ~]# systemctl restart openstack-nova-conductor.service [root@ovm02 ~]# systemctl restart openstack-nova-cert.service [root@ovm02 ~]# systemctl restart openstack-nova-novncproxy.service
cinder-volume、openstack-losetup 以外の Cinder サービスを再起動します。
[root@ovm02 ~]# systemctl restart openstack-cinder-api.service [root@ovm02 ~]# systemctl restart openstack-cinder-scheduler.service [root@ovm02 ~]# systemctl restart openstack-cinder-backup.service
7. iptables 無効化
iptables を無効にしてしまいます。
[root@ovm02 ~]# iptables -F [root@ovm02 ~]# systemctl disable iptables.service [root@ovm02 ~]# systemctl stop iptables.service
8. Horizon の不具合対応
Horizon Dashboard の不具合があるようなので、対処しておきます。
再ログイン時にエラーになる問題の対策。
[root@ovm02 ~]# sed -i -e "171i AUTH_USER_MODEL = 'openstack_auth.User'" /usr/share/openstack-dashboard/openstack_dashboard/settings.py
オブジェクト削除でエラーになる問題の対策。
[root@ovm02 ~]# sed -i -e '800,820 s/LOG.info(/LOG.warning(u/g' /usr/lib/python2.7/site-packages/horizon/tables/actions.py
httpd を再起動しておきます。
[root@ovm02 ~]# systemctl restart httpd.service
9. NetworkManager 停止
今回の環境特有の問題かもしれませんが、VM を再起動するとうまくネットワーク設定ができなくないようなので、OVM#1 / OVM#2 両方で、NetworkManager を停止してしまいます。
[root@ovm02 ~]# systemctl disable NetworkManager.service Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service. Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service. Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service. [root@ovm02 ~]# systemctl stop NetworkManager.service
10. OpenStack サービスの設定変更（追加で）
マニュアルにない分も、いくつかサービス設定を変更してみました。
OVM#1 でのサービス無効化
Nova
[root@ovm01 ~]# systemctl disable openstack-nova-api openstack-nova-cert openstack-nova-conductor openstack-nova-consoleauth openstack-nova-novncproxy openstack-nova-scheduler [root@ovm01 ~]# systemctl stop openstack-nova-api openstack-nova-cert openstack-nova-conductor openstack-nova-consoleauth openstack-nova-novncproxy openstack-nova-scheduler

OVM#2 でのサービス無効化
Neutron
[root@ovm02 ~]# systemctl disable neutron-dhcp-agent neutron-l3-agent neutron-metadata-agent neutron-openvswitch-agent [root@ovm02 ~]# systemctl stop neutron-dhcp-agent neutron-l3-agent neutron-metadata-agent neutron-openvswitch-agent
OpenStack サービスの状態
サービスは、微妙なものもありますが下記のような状態にしました。
mysqld が起動していて「disabled on boot」なのは、mariadb に変更されたことが原因のようです。

Horizon Dashboard から見た様子
Horizon Dashboard は、OVM#2 の TCP 443番ポートで提供されます。
サービスタブの状態です。さりげなく右下に「REDHATVERSION」とあります。
Nova のサービスです。
稼働中にしているのは赤枠部分のみです。システム情報には、デフォルトだと不要なエントリが登録されたままになっているので、今回のホスト名でフィルタしてあります。
Cinder のサービスです。
Neutron のエージェントはとりあえず無効にしてみました。
以上。
