Proxmox is the open-source hypervisor for hosting virtual machines and containers. In this guide, we will install Proxmox VE on top of a Debian 10 server. This install method does not require any ISO files to be mounted. This guide does not deal with any networking configuration. We have example networking guides for a Routed Proxmox setup. We’re going to install our Proxmox server with a custom partition layout because we want to use an LVM Thinpool. It’s likely you will have a different setup like software raid.
It’s vital that you configure a hostname that resolves to your server. This means you will need to edit the /etc/hosts file. In the file you will see something like the line below, assuming you have a valid hostname configured.
127.0.1.1 nvme-fr10.domain.com nvme-fr10
You will need to edit this line to include your servers IPv4 address and not the 127.x address. Before proceeding ensure you can ping your hostname and that it responds. This means you also need to ensure you have valid A records in place. You can also use hostname –ip-address to check.
Add Proxmox Repository
Add the Proxmox repository and key then update and upgrade. This will allow you to download Proxmox VE to your server.
# Add Repository echo "deb http://download.proxmox.com/debian/pve buster pve-no-subscription" > /etc/apt/sources.list.d/pve-install-repo.list # Add Key wget http://download.proxmox.com/debian/proxmox-ve-release-6.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg chmod +r /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg # Update & Upgrade apt update && apt full-upgrade
Uninstall Current Firmware
Proxmox VE comes with it’s own software so to avoid any conflicts, remove any existing firmware.
aptitude -q -y purge firmware-bnx2x firmware-realtek firmware-linux firmware-linux-free firmware-linux-nonfree
Install Proxmox VE
Now, install Proxmox to your server. This will take some time. Once the install has completed, reboot the server.
apt-get install proxmox-ve
Final Proxmox Install Checks
Once rebooted you should now see the Proxmox kernel loaded. To check use uname -rv
5.4.106-1-pve #1 SMP PVE 5.4.106-1 (Fri, 19 Mar 2021 11:08:47 +0100)
The KVM module should also be loaded. To check use lsmod | grep kvm
kvm_intel 253952 0 kvm 659456 1 kvm_intel irqbypass 16384 1 kvm
If the KVM module is not loaded you can load the module with the following commands.
# Intel CPUs modprobe kvm modprobe kvm_intel # AMD CPUs modprobe kvm modprobe kvm_amd
That’s the install of Proxmox VE completed and you can access the control interface by navigating to the hostname you configured at the start of this article followed by :8006, https://host.domain.com:8006
