Ganeti is a cluster management software that allows you to manage virtual machines and other resources on a cluster of physical servers. In this tutorial, we will learn how to install Ganeti on OpenSUSE Latest.
Before we begin, ensure that you have the following:
Ensure that your OpenSUSE system is up to date by running the following commands:
sudo zypper update
Ganeti requires several packages, which we can install using the following command:
sudo zypper install ganeti2
The installation process will take a few moments to complete.
After the installation is complete, we need to configure Ganeti. The main configuration file for Ganeti is located at /etc/ganeti/cluster.conf. We will use the gnt-cluster command to create our cluster configuration file:
sudo gnt-cluster init --no-install-create-disks --enabled-hypervisors=kvm hypervisor1.example.com hypervisor2.example.com
Replace hypervisor1.example.com and hypervisor2.example.com with the hostnames of your physical servers running on your cluster.
After you run this command, you can edit /etc/ganeti/cluster.conf to configure additional cluster settings. Note that some settings require you to stop and start Ganeti to take effect.
Now that we have installed and configured Ganeti, we can start the service:
sudo systemctl start ganeti
To check that Ganeti is running properly, use the following command:
sudo systemctl status ganeti
If everything is working properly, the status should report that Ganeti is active and running.
In this tutorial, we have learned how to install and configure Ganeti on OpenSUSE Latest. With this software, you can easily manage virtual machines and other resources on a cluster of physical servers.
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!
