Duplex Virtual Environment
Controller-0 Host Installation
Installing controller-0 involves initializing a host with software and then applying a configuration from the command line. The configured host becomes Controller-0.
Procedure:
- Using an ISO image of StarlingX, initialize the controller host via Libvirt/QEMU.
- Configure the controller using the config_controller script.
Initializing Controller-0
This section describes how to initialize StarlingX in host Controller-0. Except where noted, all the commands must be executed from a console of the Workstation. Make sure Virtual Machine Manager is open.
Run the libvirt qemu setup script:
$ bash setup_all_in_one.sh
From the KVM/VirtManager window, power on the host to be configured as Controller-0 and show the virtual machine console and details:
- When the installer is loaded and the installer welcome screen appears in the Controller-0 host, select the type of installation "All-in-one Controller Configuration".
- Select the "Graphical Console" as the console to use during installation.
- Select "Standard Security Boot Profile" as the Security Profile.
- Monitor the initialization until it is complete. When initialization is complete, a reboot is initiated on the Controller-0 host, briefly displays a GNU GRUB screen, and then boots automatically into the StarlingX image.
Log into Controller-0 as user wrsroot, with password wrsroot. The first time you log in as wrsroot, you are required to change your password. Enter the current password (wrsroot):
Changing password for wrsroot. (current) UNIX Password:
Enter a new password for the wrsroot account:
New password:
Enter the new password again to confirm it:
Retype new password:
Controller-0 is initialized with StarlingX, and is ready for configuration.
Configuring Controller-0
This section describes how to perform the Controller-0 configuration interactively. Except where noted, all the commands must be executed from the console of the active controller (here assumed to be controller-0.
When run interactively, the config_controller script presents a series of prompts for initial configuration of StarlingX. The prompts are grouped by configuration area. To start the script interactively, use the following command, in the System mode select Simplex as the configuration option and accept all the default values for the rest of the options:
controller-0:~$ sudo config_controller
The output when config_controller script is run interactively is:
... System mode. Available options are: 1) duplex-direct: two node-redundant configuration. Management and infrastructure networks are directly connected to peer ports 2) duplex - two node redundant configuration 3) simplex - single node non-redundant configuration System mode [duplex-direct]: 2 ... WARNING: Command should only be run from the console. Continuing with this terminal may cause loss of connectivity and configuration failure ... Apply the above configuration? [y/n]: y Applying configuration (this will take several minutes): 01/08: Creating bootstrap configuration ... DONE 02/08: Applying bootstrap manifest ...

DONE Configuration was applied Please complete any out of service comissioning steps with system commands and unlock controller to proceed.
Controller-0 Host Provision
On Controller-0, acquire Keystone administrative privileges:
controller-0:~$ source /etc/nova/openrc
On Controller-0, create a newshell script file, copy and paste the content below and run:
The host is rebooted. During the reboot, the command line is unavailable, and any ssh connections are dropped. To monitor the progress of the reboot, use the controller-0 console.
Verifying the Controller-0 Configuration
On Controller-0, acquire Keystone administrative privileges:
controller-0:~$ source /etc/nova/openrc
Verify that the Titanium Cloud controller services are running:
[wrsroot@controller-0 ~(keystone_admin)]$ nova service-list +--------------------------------------+------------------+--------------+----------+---------+-------+ ... | Id | Binary | Host | Zone | Status | State | ... +--------------------------------------+------------------+--------------+----------+---------+-------+ ... | d7cdfaf0-9394-4053-b752-d609c837b729 | nova-conductor | controller-0 | internal | enabled | up | ... | 692c2659-7188-42ec-9ad1-c88ac3020dc6 | nova-scheduler | controller-0 | internal | enabled | up | ... | 5c7c9aad-696f-4dd1-a497-464bdd525e0c | nova-consoleauth | controller-0 | internal | enabled | up | ... +--------------------------------------+------------------+--------------+----------+---------+-------+ ...
If one of the listed services is down please reenable
#!/usr/bin/env bash
source /etc/nova/openrc
ALL_DISABLED_SERVICES=`nova service-list | grep disabled | awk -F "|" '{print $2}'`
for service in $ALL_DISABLED_SERVICES; do
nova service-force-down --unset ${service}
nova service-enable ${service}
done
Verify that controller-0 is unlocked, enabled, and available:
