Proxmox VE subscriptions

Proxmox Virtual Environment (aka PVE) is free open software (see this page for info about license, sources etc), and the company that developed it (Proxmox Server Solutions GmbH) offers support in many ways, with different support channel, level and pricing.

The only authoritative place for all options, pricing and all commercial details is the "Proxmox Server Solutions GmbH" company server PVE section (, which can redirect you to the "" domain - belonging to "Maurer IT Systemlösungen KG" - for buying commercial options such as support subscriptions.

In particular, here you can find more information:

About the relation beetween "Proxmox Server Solutions GmbH" and "Maurer IT Systemlösungen KG" see:

About this page

This wiki page only has the purpose to collect and link all the information and instructions related to the subscriptions and the Proxmox VE system usage and experience.

Please do not refer to what follows as "official commercial information", like pricing, banking details, and such: see above links for that.

the 3.1 change

Since version 3.1 subscriptions became more "evident" to Proxmox VE users, because on nodes without any subscription registered, users started to get a message each time logging into each node's web gui ("You do not have a valid subscription for this server. Please visit to get a list of available options."). That message was a part of a partial change in the Proxmox VE repositories organization, in part related to subscription options, and many users initially complained a lot on the community forums before fully understanding the reason for that message, what changed, and so on.

Proxmox Server Solutions GmbH stated then clearly their point about Proxmox VE Support Subscriptions - and why everybody should buy one (see this forum sticky post).

Your Proxmox VE node/cluster will work even if you have no subscription, and you will get support through the forums too (by Proxmox team and users/volunteers), but:

  • you will get the message each time you log into each node's web gui ("You do not have a valid subscription for this server. Please visit to get a list of available options.")
  • you will not be able to access the enterprise (stable) repositories
  • you will not get support in any other way (Customer Portal, SSH)
  • you will not get any support tickets

If you understand the value of the work provided by the Proxmox team by creating, maintaining and evolving a powerful system like Proxmox VE, and supporting anyone through community forums, you should buy subscription for (at least) your production systems: you'll get the benefits in the future.

Payment options

You can pay subscription by bank transfer, PayPal (including credit cards): refer also to

A few notes:

  • bank transfer: this is the preferred method, as it cost less to Proxmox team, related details are provided by the related site (see above links)
  • PayPal: this will also allow you to pay with your credit card, if supported by PayPal (even if you have no PayPal account)

Available subscriptions and how to calculate total amount

See also and

There are different subscription levels available, with pricing related to CPU & covered months.

(price / CPU & month) x (sockets count) x (subscription months)

By "CPU" it's meant physical socket used, ie what is the output of this command on the Proxmox VE command line, on each node:

cat /proc/cpuinfo | grep "physical id" | sort | uniq | wc -l

if it outputs 2, then you have 2 sockets on that node, so your subscription for that node will be, eg:

(AMOUNT eur) x (2 sockets) x (12 months) = (24 x AMOUNT) eur

You need to have enough sockets licensed for all the nodes under subscription, eg if you have:

  • 3 nodes with 2 sockets each

you need

  • 3 2-CPU socket subscription

Subscription keys usage

See also

Once you pay for subscription, you will get subscription keys that must be uploaded to your nodes.

You can do this through the web GUI:

  • Select a node
  • Scroll down to the "Subscription" tab, click on it
  • Click the "Upload subscription key" button
  • Paste there your subscription key, and press OK

The enterprise repository is enabled by default, see also Package Repositories.

Note: it will take some time (a few minutes) for your subscription to be registered, so don't expect "enterprise repositories" to work immediately.

Apart from that, if you feel your subscription is not working, open a request via the above sites (see
