Learn how to – How To Install Proxmox VE 7 on Debian 11 (Bullseye).
Virtualization is the foundation of cloud computing as it allows for more efficient usage of physical computer hardware. In Virtualization, a software application is used to create an abstraction layer over hardware elements of a computer – processors, memory, storage, network and more, to be divided into multiple virtual machines (VMs). Proxmox Virtual Environment (VE) is a Virtualization solution based on Debian Linux distribution with a modified LTS kernel. It enables you to deploy and manage both virtual machines and containers, with unified storage for better efficiency.
In this guide, we will cover a step-by-step installation of Proxmox VE 7 virtualization software on Debian 11 (Bullseye) Linux system. It’s recommended to deploy Proxmox VE server from a Bare-metal_ISO_Installer, but it’s sometimes inevitable to deploy it on a running instance of Debian 11 (Bullseye) server.
Setup Pre-requisites
For the installation of Proxmox VE 7 on Debian 11 (Bullseye), you need the following requirements to be met;
- A running instance of Debian Bullseye
- A 64-bit processor with support for the Intel 64 or AMD64 CPU extensions.
- Access to Debian server terminal as root or standard user with sudo
- Server needs internet access
- Enough hardware resources to be used in Virtualizing other operating systems
We have a guide that helps with the installation of Debian 11 (Bullseye) operating system. In the link below:
With all the requirements satisfied, proceed with the installation of Proxmox VE 7 on Debian 11 (Bullseye) with the steps discussed in the next sections.
For Proxmox VE 6, check out: How To Install Proxmox VE 6 on Debian 10 (Buster)
Step 1: Update Debian OS
Ensure your Debian 11 (Bullseye) operating system is upgraded.
sudo apt -y update && sudo apt -y upgradeOnce the upgrade process is complete, reboot the server if needed.
[ -f /var/run/reboot-required ] && sudo reboot -fStep 2: Set Proxmox Server hostname
Let’s set a hostname on the server
sudo hostnamectl set-hostname pve01.example.com --staticReplacepve01.example.com with correct hostname you’re setting on your system.
Get the IP address of the primary interface:
$ ip ad
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: enp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 52:54:00:ef:22:c5 brd ff:ff:ff:ff:ff:ff
inet 192.168.200.50/24 brd 192.168.200.255 scope global dynamic noprefixroute enp1s0
valid_lft 1982sec preferred_lft 1982sec
inet6 fe80::5054:ff:feef:22c5/64 scope link noprefixroute
valid_lft forever preferred_lft foreverUpdate the record on /etc/hosts file with hostname and matching IP address for local resolution without DNS server.
$ sudo vim /etc/hosts
192.168.200.50 pve01.example.com pve01Logout and back in to use new hostname
$ logoutTest if configured hostname is is ok using the hostname command:
$ hostname --ip-address
192.168.200.50Step 3: Add the Proxmox VE repository
The Proxmox server packages are distributed in an APT repository. Add the repository to your Debian 11 system by running the commands below:
echo "deb http://download.proxmox.com/debian/pve bullseye pve-no-subscription" | sudo tee /etc/apt/sources.list.d/pve-install-repo.list
Then import GPG packages signing key:
wget http://download.proxmox.com/debian/proxmox-release-bullseye.gpg
sudo mv proxmox-release-bullseye.gpg /etc/apt/trusted.gpg.d/proxmox-release-bullseye.gpg
chmod +r /etc/apt/trusted.gpg.d/proxmox-release-bullseye.gpgUpdate your APT sources list
$ sudo apt update

This is Proxmox VE’s main Ceph repository and holds the Ceph packages for production use. You can also use this repository to update only the Ceph client.
echo "deb http://download.proxmox.com/debian/ceph-pacific bullseye main" | sudo tee /etc/apt/sources.list.d/ceph.listStep 4: Install Proxmox VE 7 packages
With the repository added, we can now install Proxmox VE packages on Debian 11 (Bullseye) system:
sudo apt update
sudo apt install proxmox-ve postfix open-iscsiThe installation time will depend on other variables such as internet connectivity and hard disk write speed:

[Y/n] yIf you have a mail server in your network, you should configure postfix as a satellite system, and your existing mail server will be the ‘relay host’ which will route the emails send by the proxmox server to the end recipient. If you don’t know what to enter here, choose local only.
Confirm system mail name / update accordingly.
