Ganeti is an open-source virtualization management software that allows you to create and manage virtual machines on a cluster of physical machines. In this tutorial, we will learn how to install Ganeti on nixOS latest.
Before you begin, make sure that you have the following prerequisites:
sudo nix-env -i ganeti
sudo nano /etc/ganeti/default-config.yml
Configure the following settings in the file:
cluster_name
: Set the name of your cluster.use_external_mip_script
: Set it to true
if you have a script that manages the external IP address of your cluster.default_max_mem_size
: Set the maximum memory size that a virtual machine can use.default_vcpus
: Set the default number of virtual CPUs for a virtual machine.enabled_hypervisors
: Set the hypervisors that you want to use in your cluster. The available options are kvm
and xen
.hvparams
: Set the parameters for the hypervisors that you have enabled in the previous step.instance_communication_network
: Set the network to be used for communication between virtual machines.Save and close the configuration file.
sudo systemctl start ganeti
sudo systemctl status ganeti
If everything is running correctly, you should see a status message indicating that Ganeti is active and running.
sudo gnt-cluster init mycluster.example.com
Replace mycluster.example.com
with the name that you set for your cluster in Step 2.
Congratulation! You have successfully installed Ganeti and created a cluster on nixOS latest. You can now create and manage virtual machines on your cluster.
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!
