How to Install Ganeti on NetBSD

Ganeti is an open source virtual machine manager that allows you to create and manage instances of virtual machines. In this tutorial, we will guide you on how to install Ganeti on NetBSD.

Prerequisites

• A NetBSD-based operating system (such as NetBSD 8.2)
• Root access to the server
• Basic knowledge of the command-line interface
• A network connection

Installing Ganeti

1. Open the terminal and log in as the root user.
2. Update your package manager by running the following command:

pkgin update

3. Install the required packages by running the following command:

pkgin install python27 python27-setuptools python27-simplejson python27-dev py27-virtualenv py27-distribute \
    py27-pip py27-paramiko py27-openssl py27-netifaces py27-psutil py27-pyasn1-modules py27-ipaddr \
    libpri libxml2 libxslt

4. Create a virtual environment by running the following command:

virtualenv /opt/ganeti-virtualenv

5. Activate the virtual environment by running the following command:

source /opt/ganeti-virtualenv/bin/activate

6. Install Ganeti with pip by running the following command:

pip install ganeti

7. Configure the Ganeti installation:

   a. Create a directory named "ganeti" in the "/etc" directory by running the following command:

   mkdir /etc/ganeti
   

   b. Create a file named "ganeti-setup.conf" in the newly created "ganeti" directory and add the following lines to it:

   ## - Ganeti Configuration file - ##
   ## - WARNING: Do not edit this file directly! Edit /etc/ganeti/site.conf,
   ## - and run 'gnt-cluster init' after making any change.
   ##
   
   # Cluster settings
   CLUSTER_NAME = 'ganeti-cluster'
   CLUSTER_DOMAIN = 'example.com'
   IPolicyDir = '/var/lib/ganeti/iallocators'
   
   # Hypervisor settings
   HV_GENERATION_DIR = '/var/lib/ganeti/hvgen'
   HV_DEFAULT_TYPE = 'kvm'
   HV_DEFAULT_CDROM_IMAGE_PATH = '/srv/ganeti/kvm-cdrom.iso'
   
   # Instance settings
   DISK_TEMPLATE_DEFAULT = 'plain'
   NIC_PARAMS = [('mode', 'bridged'), ('link', 'eth0')]
   
   # Network settings
   NETWORK_PORT = 1812
   LIVEMIGRATION_PORT = 8002
   FILE_DRIVER = 'raw'
   
   # User settings
   # For the authentication method, either the first item or both items
   # may be set to None, to specify a default or non-existent method.
   # AUTH_USER_SHADOW = ("*", "*")
   AUTH_USER_LIST = ["root"]
   AUTH_GROUP_LIST = []
   
   # Miscellaneous settings
   SSH_CONSISTENT_AUTH = False
   INSTANCE_COMMUNICATION_NETWORK = 'cluster'
   BACKUP_DIR = '/var/lib/ganeti/backup'
   MASTER_SCOREBOARD_PATH = '/var/run/ganeti/master-scoreboard'
   
   ## --- END of Ganeti Configuration file ---
   

   c. Create a symbolic link to the site configuration file by running the following command:

   ln -s /etc/ganeti/ganeti-setup.conf /etc/ganeti/siteconf.cfg
   

8. Initialize the Ganeti cluster:

   a. Create a directory named "/var/lib/ganeti" by running the following command:

   mkdir -p /var/lib/ganeti/iallocators
   

   b. Run the following command to initialize the Ganeti cluster:

   gnt-cluster init --auto-scaling OFF --no-ssh-init
   

   c. Follow the prompts and enter the requested information when prompted.

9. Once the installation is complete, verify that Ganeti is running correctly by running the following command:

gnt-cluster verify

Congratulations! You have successfully installed Ganeti on NetBSD. You can now start using Ganeti to create and manage virtual machines.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
