How to Update Proxmox VE When “You Do Not Have A Valid Subscription”

If you have recently dove into the Proxmox VE world, your mind is probably blowing chunks.  Proxmox gives you the unmatched ability to run hypervisor-like Virtual Machines, as well as containers, side by side with High Availability.  It’s an amazing virtualization platform and if you haven’t tried it out yet I highly recommend you do so.  After installing Proxmox 4.2 on one of my lab servers, I found the need to update it and I wasn’t about to pay for an Enterprise Subscription for my home lab.


How to update Proxmox when “You do not have a valid subscription for this server, please visit to get a list of available options” and keep you Proxmox server updated!”

There are a few steps involved and they go something like this:

  1. Disable the enterprise repository that is configured by default
  2. Add the no-subscription repository
  3. Update apt so it knows what can be updated
  4. Use apt to upgrade any packages
  5. Upgrade the entire distribution, using apt, of course

First, lets disable the enterprise repository.  You can’t run apt-get update by default without a subscription, you will get an error.  So, lets comment out that repo so it isn’t checked.  Go ahead and putty / ssh / console into your Proxmox server, and run the following command:

sed -i.bak 's|deb jessie pve-enterprise|\# deb jessie pve-enterprise|' /etc/apt/sources.list.d/pve-enterprise.list

How To Add An iSCSI Target To Proxmox VE 3.4 And Create LVM Group

I’ve been digging into Proxmox VE 3.4 quite a bit lately. I have a FreeNAS server on my network that I use for VM storage in my lab. When I went to add an iSCSI target on Proxmox for virtual machine and image storage, it was a bit confusing. So, I thought I would put a quick step by step guide together to help other folks in the same boat. Here goes.

How to add an iSCSI target in Proxmox

First, log into your Proxmox VE 3.4 server via the web interface. Make sure Datacenter (top level) is selected in the left pane, and make sure you are on the Storage tab on the right pane. It should look like this.

Installing Proxmox VE 3 from a USB Thumb Drive

I recently decided to venture into the Proxmox virtualization world. Being a VCP, i’ve always used VMWare based virtualization for just about everything. I have played around with Xen before, but most all of my virtualization endevours have been purely hypervisor “bare-metal” based. When I found out the Proxmox seems to be the best of both worlds, with hypervisor and container based virtualization in one package, I was intrigued. So, I looked for a quick how-to on creating a bootable thumbdrive to install Proxmox (I don’t have a CD drive on the server, nor any of my servers now that I think about it). I’m using OSX as my primary OS, so I was happy to find that the .ISO could be copied to a USB thumbdrive with one simple command (works on OSX and Linux):

dd if=pve-cd.iso of=/dev/XYZ bs=1M

I plugged in an 8GB USB thumbdrive and needed to figure out what the /dev/ device name was, so I could format the command properly. So, google search it was. I felt pretty stupid when I found out that running this single command, would give me the info I needed:

$ mount
