How to Install and Set Up Proxmox VE 8.4

Posted on May 25, 2025May 25, 2025 by kotenkoo

After spending time with cloud platforms like Azure, AWS, and DigitalOcean — as well as Type 2 hypervisors (like VirtualBox) — I decided to try something new: a Type 1 hypervisor installed directly on hardware. My choice? The open-source, free, and powerful Proxmox VE (Virtual Environment).

Here’s a step-by-step walkthrough of how I installed and configured Proxmox VE 8.4, along with some beginner-friendly notes for those new to bare-metal setups 💡


🛠️ Step 0 – Check System Requirements

Before diving into installation, make sure your hardware is compatible with Proxmox. You’ll need:

  • A dedicated server or machine
  • Virtualization support (VT-x / AMD-V)
  • At least 4 GB RAM (8 GB or more recommended)
  • SSD or HDD with enough space

💽 Step 1 – Download the ISO

Go to the official Proxmox VE website and download the latest LTS version of the ISO installer.


🔧 Step 2 – Create a Bootable USB Drive

Use Rufus to create a bootable USB stick.
When prompted with the warning ISOHybrid image detected, don’t worry — just click Start ✅


💻 Step 3 – Boot from USB and Start Installation

You’ll need physical access to the server.

  1. Plug in the USB stick
  2. Enter BIOS/UEFI
  3. Change the boot order to boot from USB
  4. Start the Proxmox installer

(Installing Proxmox feels similar to installing any OS — because under the hood, Proxmox is Debian Linux 🐧)


⚙️ Step 4–7 – Installation Configuration

You’ll go through several steps:

  • Disk selection for the Proxmox installation
  • Region, timezone, and keyboard layout
  • Root password
  • Hostname, IP address, gateway, and DNS settings

🔐 Step 8 – First Login via Console

Once installed, you’ll see the “Welcome to Proxmox”, use:

  • Username: root
  • Password: the one you just set

🔎 At first, I wasn’t sure which user to log in as — in the cloud it’s often admin, but here it’s root. If you see the following screen, you’ve logged in successfully:


🌐 Step 9 – Network Setup for Web Interface Access

To use the GUI, you’ll need a second computer on the same network as your Proxmox server.

🔌 Option: Direct LAN connection

We’ll use a direct Ethernet cable (UTP) connection:

  • On your PC, assign: 192.168.1.1/24
  • On the server, assign: 192.168.1.100/24

Edit the network configuration file on the server: nano /etc/network/interfaces


📝 Step 10 – Update Network Settings

You’ll likely see 3 interfaces: lo, eno1, and vmbr0.

Update vmbr0 like this: address 192.168.1.100/24 gateway 192.168.1.254 (The gateway is optional for local-only setups).

Save changes with:

  • Ctrl + O to write
  • Ctrl + X to exit

🔄 Step 11 – Restart Network

Apply the changes by restarting networking: systemctl restart networking


✅ Step 12 – Test and Access the Web UI

From your PC, ping the server: ping 192.168.1.100

If ping works — go to your browser and enter: 192.168.1.100:8006

You’ll see the Proxmox Web UI login screen:

Log in with root and the password you set earlier.


🧠 Final Notes & Tips

  • Browser warnings: The certificate is self-signed — you can safely proceed
  • If ping fails: Double-check IPs, cables, and subnet masks
  • Security tip: Consider setting up a firewall and restricting access to port 8006
  • Updates: Run apt update && apt full-upgrade regularly to keep the system secure

✨ WARNING: I won’t swear by 100% accuracy – consider it more like my interpretive dance with the topic!

    Texas Hold’em isn’t just about cards-it’s a battle of minds. Much like crafting beats in the Sprunki Christmas Game, success in poker requires timing, creativity, and reading the room. Both demand strategy and flair.
