Installing Proxmox on OVH

Overview

This guide covers the installation of Proxmox VE 8.3 on OVH dedicated servers. Since OVH's standard OS templates don't include above Proxmox 7, we'll use IPMI/KVM to perform a custom installation.

Server Requirements

  • A dedicated server from OVH's eco or regular ranges
  • IPMI access (available on most OVH servers)
  • Kimsufi servers: IPMI support varies by model, verify before proceeding

Preparation Steps

1. Download Required Files

2. Access IPMI Console

  1. Log into your OVH manager
  2. Navigate to your server's management page
  3. Locate and click the IPMI/KVM option:

OVH Manager IPMI/KVM

KVM Access Options

  • Web KVM: Try this first - easier to use and may support virtual media
  • Java KVM: More reliable but requires Java installation

3. Mount Installation Media

  1. Open the Virtual Media tool in your KVM session: IPMI Virtual Media tool

  2. Browse and select your Proxmox ISO: Virtual Media Wizard

  3. Ensure the media is connected: Virtual Media Wizard: Drive Redirected

4. Boot Configuration

  1. Reboot the server through IPMI: IPMI Server Power Control Action Confirmation

  2. Enter BIOS and select the virtual CD/DVD as boot device: BIOS Boot Device selection

Boot Device Selection

Some KVM implementations will have an option to select the next boot device ahead of time, but this isn't always available. You may need to enter BIOS manually.

Installation Process

1. Initial Setup

Boot from the Proxmox VE ISO and select "Install Proxmox VE": Proxmox VE 8.3 ISO initial boot screen

Follow the initial prompts:

  • Accept the EULA
  • Select target disk
  • Set location and timezone
  • Create root password

2. Network Configuration (OVH-Specific)

Critical Step

This step requires specific OVH network information. Incorrect configuration can result in loss of access to your server.

Identify the Correct Network Interface

You'll see this network configuration screen: PVE Installation: Management Network Configuration

To configure it correctly:

  1. In OVH Manager, locate your server's network information: OVH Manager: Network Interfaces

  2. Note the active interface and its configuration: OVH Manager: Server Network Info

Configure Management Network

Use the information from OVH Manager to configure your management interface:

yaml
Required Information:
- Hostname: proxmox.yourdomain.com
- IP Address: Your main IP
- Netmask: 255.255.255.255 (OVH typically uses /32)
- Gateway: Your gateway IP
- DNS Server: 213.186.33.99 (OVH DNS)

Enter these details in the network configuration screen: PVE Management Network Configuration populated

3. Complete Installation

Monitor the installation progress: PVE Installation in progress

Wait for completion: PVE Installation Successful

Post-Installation Steps

1. Disable Rescue Mode

Important

Your server will boot to rescue mode unless disabled in OVH Manager!

  1. Access OVH Manager: OVH Manager disable rescue mode

  2. Enable "Boot from hard disk": OVH Manager boot from the hard disk

2. Access Proxmox Web Interface

  1. Open your browser and navigate to:

    https://your-server-ip:8006
  2. Log in with root credentials: PVE Manager Login Screen

Next Steps

Proceed to Initial Configuration
