This guide has been written to help Linux and Cloud users to install and configure Proxmox VE 7 on Hetzner root server. Root server in Hetzner Cloud is a dedicated server which is completely isolated from one another to give you full access and control to configure the server anyway you want without affecting other users. Hetzner Online GmbH provides auctions for dedicated server hardware at a very competitive rates with a monthly payment model. Visit Hetzner Server auction page to bid on servers and save money.
Proxmox Virtual Environment (VE) is a very powerful and enterprise-grade server virtualization software using Debian Linux as its base with a modified Linux kernel. With Proxmox you can run both Virtual Machines and Containers powered by KVM and LXC technologies respectively. The Proxmox VE source code is free, released under the GNU Affero General Public License, v3 (GNU AGPL, v3).
This guide is intended for personal Labs only. We’ll do a single node installation of Proxmox VE Server on Debian 11 (Bullseye) operating system. It comes with an integrated graphical user interface (GUI) for management, there is no need to install a separate management tool. For a multi-node Proxmox VE Cluster setup, visit the official Proxmox VE High Availability to read more if interested with the solution.
In this article, we shall perform installation of Proxmox VE 7 on a Hetzner root server with the following hardware specifications.
CPU: Intel(R) Xeon(R) CPU E5-1650 v3 @ 3.50GHz (Cores 12)
Memory: 256GB RAM
Disk: 2 x 480GB SSD
Network: 1Gbit
IPV4 Addresses: 1 x IPV4 public addressWhen you order an hetzner root server, by default, you get a single IPv4 public IP address. If you need more public addresses, you’ll have to order separately.
Step 1 – Boot the Server in to Rescue Mode
Login to your Hetzner root server console and move Main functions > Servers > Server Label > Rescue section to boot your server in rescue mode.
From the page shown, select the Operating system, CPU Architecture, and public key or password and click on “Activate rescue system” to use activate rescue system.
After activating rescue system, the system has to be rebooted. This is done on Server > ServerName > Reset section in the console.
Step 2 – Create Root Server Configuration.
SSH to the server in rescue mode using root user and password shown during Rescue activation.
$ ssh root@serverip
Welcome to the Hetzner Rescue System.
This Rescue System is based on Debian 9 (stretch) with a newer
kernel. You can install software as in a normal system.
To install a new operating system from one of our prebuilt
images, run 'installimage' and follow the instructions.

As seen from the output, the server we’re using has two disks @480GB. We’ll configure them in non-redundant RAID 0 configuration.
Disk /dev/sda: 480 GB (=> 447 GiB)
Disk /dev/sdb: 480 GB (=> 447 GiB)Next we create our Hetzner server installer configuration file. We’ll name it debian-install-config.txt
vim install-config.txtThis is the data populated that will be used by the installimage to install Debian 11 (Bullseye) operating system from pre-built image.

Configure your own partitioning scheme depending on storage hardware and usable space.
Step 3 – Install Debian 11 (Bullseye) on Hetzner root server
With correct installer configurations, initiate the installation process of Debian Linux on Hetzner root server by running the following command:
# installimage -a -c install-config.txtInstallation process will start immediately after command execution:
Found AUTOSETUP file '/autosetup'
