Proxmox Virtual Environment 9.0 released!

Please note that the documentation contains a small error.
This document (on the Downloads page)
https://www.proxmox.com/en/download.../documentation/proxmox-ve-admin-guide-for-9-x

FAQ section, question 12 (upgrade to major release), on page 444:
The text "Upgrade from Proxmox VE 8 to 9 has the link (in the PDF) https://pve.proxmox.com/wiki/Upgrade_from_7_to_8

Fortunately one can easily rewrite the URL https://pve.proxmox.com/wiki/Upgrade_from_8_to_9

Possible this may affect the HTML help inside the ISO as well.

Thank you.

Thanks for reporting this! I pushed a fix in git, should get fixed with the next pve-docs version bump, after which we can update this PDF.

@t.lamprecht please update 8to9 instructions to clearly indicate to NOT UPGRADE if your are running mellanox/nvidia networking. They do not support debian 13, and you will wind up with a broken system, requiring a fresh install (if running vendor drivers).

Successfully upgraded 14 physical hosts and 5 virtual hosts. :D

One particular host had some custom built drivers for 5G modem and a custom firmware networking smart card, but after recompiling drivers for new kernel, all done.

Impressed with you guys, Proxmox upgrades sure have come a long way, nearly point-n-click.

My testlab hardware across the board from Intel to AMD Epycs is configured with all kinds of customized scripts etc such as mellanox nics with custom drivers, gpu/storage virtual functions/sr-iov, nested virtualisation, nvme sr-iov etc...... was glad the upgrade only cost me a couple cans of cola with some retrosynth tunez in the background.

Holding the flag high for free homelab software, thank you soooo much. :)

Hi, new to all this... I've been on a bit of a merry song and dance between Trixie and Bookworm on an attempted Proxmox VE local install, because although the downloads page at https://www.proxmox.com/en/downloads says I'm downloading version 9.0-1, when I checked it with the Windows checksum hash matching algorithm and then got Gemini to match to the hash from the downloads page, it suggested that it was actually Proxmox 8 via the download link even though it was labelled Proxmox 9:
Yes, they are an exact match. ✅
Comparison
  • Hash from your certutil error:228f948ae696f2448460443f4b619157cab78ee69802acc0d06761ebd4f51c3e
  • Hash I identified (Proxmox VE 8.0.2):228f948ae696f2448460443f4b619157cab78ee69802acc0d06761ebd4f51c3e
Conclusion
This confirms that your downloaded file, named proxmox-ve_9.0-1 (1).iso, is actually the Proxmox VE 8.0.2 installer.

Even though the filename says version 9.0-1, the file's content is verifiably version 8.0.2. If you need the newer version, you should download it again from the official Proxmox website.

Can someone please check this and get back to me?

Eh, I would not trust "AI" too much, especially not for any integrity things and if it's just comparing a simple string...
The SHA256 sum from proxmox-ve_9.0-1.iso is indeed 228f948ae696f2448460443f4b619157cab78ee69802acc0d06761ebd4f51c3e as listed on www.proxmox.com and in the signed SHA256SUMS file on https://enterprise.proxmox.com/iso/

Just check yourself (without LLM).

Then report the issue to Google please and not here ;) And I suggest you read up more on what LLMs can and cannot do and not just trust marketing hype.

I upgraded my Epyc 8434P with Asrockrack SIENAD8-2L2T. I went from Proxmox 8.4 with kernel 6.11 to Proxmox 9 with kernel 6.14. Unfortunately it went unstable, crashing with nothing in the logs twice in 24 hours. I reverted to kernel 6.11 again (still in Proxmox 9) and it's stable for a few days again.

I still suspect PCIe sharing to VM (SATA to a TrueNAS VM) causing the crash due to a bug in 6.14, which is supposedly not fixed until kernel 6.16.

So I will make a try with the new opt-in kernel 6.17 soon.
