Configuring High-Availability Clusters with Proxmox VE


Implementing a high-availability (HA) cluster with Proxmox VE on ServerStadium’s infrastructure (VM Pricing, Dedicated Servers) enables robust and resilient server management. It’s ideal for businesses seeking to maximize uptime and provide reliable service continuity.


  • Two or more ServerStadium VMs or dedicated servers (VM Pricing, Dedicated Servers).
  • Basic knowledge of virtualization, Linux server administration, and networking.
  • Proxmox VE installed on each server.

Step 1: Set Up ServerStadium Servers for Proxmox

  1. Choose Servers: Select at least two ServerStadium servers to form your HA cluster.
  2. Prepare Servers:

    sudo apt update
    sudo apt upgrade

Step 2: Install Proxmox VE

  1. Install Proxmox:

    Install Proxmox VE on each server. Follow the official installation guide provided by Proxmox.

Step 3: Configure the Proxmox VE Cluster

  1. Create a New Cluster:

    On the first server, create a new cluster:

    pvecm create cluster-name

  2. Add Other Nodes to the Cluster:

    On each additional server, join the cluster:

    pvecm add first-node-ip

    Replace first-node-ip with the IP address of the first server.

Step 4: Configure High Availability

  1. Set Up HA Resources:

    In the Proxmox VE web interface, convert virtual machines (VMs) or containers to HA resources.

  2. Configure HA Groups:

    Define HA groups to control which nodes can run specific VMs or containers.

Step 5: Test Cluster and HA Functionality

  1. Verify Cluster Status:

    Ensure that all nodes are correctly joined and communicating within the cluster.

  2. Test Failover:

    Simulate node failures to test if HA resources automatically migrate to other nodes as expected.


Your high-availability cluster with Proxmox VE is now set up on ServerStadium servers, offering a resilient and scalable solution for your virtualization needs. This setup ensures that your services remain available even in the event of server failure.
