Install Proxmox Free Virtual Machine Host Management

proxmox-logoProxmox is a free virtual machine manager for your home media server. Proxmox has a minimal debian base and a great web interface for creating and managing virtual machines. With Proxmox you can have separate virtual machines for each component of your home media server. For example you can have one dedicated to usenet which doesn’t use a VPN and a torrent virtual machine that is connected to the VPN constantly. Proxmox virtual machine management gives you fine tuned control over your services.

Proxmox is completely free but they do offer subscriptions for enterprise customers. I show you how to remove the license nag in Proxmox and enable distro updates so you do not have to reflash your Proxmox USB each time there is a new version.

I installed Proxmox on an old Dell Latitude E6400 Laptop from eBay which supports virtualization

Install Proxmox Free Virtual Machine Management

Download the latest Proxmox Virtual Environment image from here.

If you are on Windows, rename image iso file to .raw and burn using Rufus.

In Rufus, when you are prompted choose dd mode as the write method which should prevent the cd rom not found error during Proxmox installation (source).

Linux and Mac users should be able to use dd to write the image file.

When the machine boots to the USB stick choose Install Proxmox VE

After installation on the boot screen you will see a message showing where you can access the Proxmox Web Interface.

Use root as the username and the password you set during installation. You will get a nag screen that I show you how to remove later in this guide.

Adding ISOs to Proxmox

You can add ISO images to install operating systems by going to the Proxmox web interface or SSH.

Add ISOs to Proxmox with Web Interface

Click the local server in the left pane and click Content

Click Upload and browse to the ISO on your machine

proxmox-add-isos-web-interface-min

Add ISOs to Proxmox via SSH

If you prefer to use the command line then SSH in to Proxmox with PuTTY on port 22.

Enter this folder where Proxmox stores its ISOs (source).

cd /var/lib/vz/template/iso

Download your ISO using wget, here I am getting the Debian net installer from here.

wget http://cdimage.debian.org/debian-cd/8.5.0/amd64/iso-cd/debian-8.5.0-amd64-netinst.iso

Now you will be able to select ISOs in the Proxmox web interface when you create new virtual machines.

Remove the subscription checker and enable simple updates without a subscription all legal

Enable Free Proxmox Distro Updates

By default Proxmox leaves the sources list for Enterprise customers. You can change this to the no-subscription repository (source and here).

SSH into the Proxmox box on port 22 using the root password credentials you set during installation.

Open the PVE sources list.

sudo nano /etc/apt/sources.list.d/pve-enterprise.list

Replace the only line with this one for the Proxmox no subscription repository

deb http://download.proxmox.com/debian jessie pve-no-subscription

Ctrl=X, Y and Enter

Now you can update your Proxmox repository and upgrade like this

apt-get update
apt-get upgrade
apt-get dist-upgrade

Changing repository won’t remove the Proxmox License nag when you log in to the Proxmox web interface, see how to do that below.

Remove Proxmox License Nag

The Proxmox license nag can be irritating. Especially when you have no intention of ever using Proxmox’s Enterprise support. Luckily it is just a javascript file that can be modified.

For Proxmox 4.2 you can remove the license warning with this sed command (source and source)

sed -i.bak "s/data.status !== 'Active'/false/g" /usr/share/pve-manager/ext6/pvemanagerlib.js

You may need to reboot the Proxmox host which can be done from the Web interface.

If you still see the license nag it is probably because of browser cache so test with a fresh browser or empty the cache.

Promox is now installed and you can start creating your virtual machines.

Prevent Laptop Running Proxmox from Sleeping

I wanted to stash this laptop behind the couch but when I closed the lid the laptop went to sleep.

I managed to fix it thanks to this link

nano /etc/systemd/logind.conf

Then uncomment (remove #) and change these lines to match, save and reboot

HandleSuspendKey=ignore
HandleHibernateKey=ignore
HandleLidSwitch=ignore

If you want to avoid rebooting Proxmox when there are kernel updates then configure Kernelcare
