Proxmox Harware Requirements Windows server 2025 & Linux Red Hat 9/10

[Benziane]

Hello,



I have HPE DL380 GEN8 and GEN9 servers that I want to use to deploy the latest version of the PROWMOX virtualization platform. I would like to know whether these servers are not obsolete for hosting this platform and whether I would have any problems with the latest version of Windows Server 2025 and Linux Red Hat 9 and 10 in relation to the firmware version of this generation of servers.



Thank you very much.

There is no such thing as a "hardware compatibility list" for ProxmoxVE (Proxmox Virtualization, Proxmox is the company Proxmox Server Solutions GmbH). It's based on Debian Bookworm and an Ubuntu kernel, so if your servers can run on Debian or Ubuntu they will most likely work with ProxmoxVE too.

For Windows Server 2025 you will want to read and apply https://pve.proxmox.com/wiki/Windows_2025_guest_best_practices to get most out of it.
One caveat though: You might need to change the cpu type in your VM configuration to get a better performance: https://forum.proxmox.com/threads/t...-of-windows-when-the-cpu-type-is-host.163114/

I can't say anything in regard to RHEL, but I wouldn't expect any problems.

Look Up the specs of Server 2025 and determine how much RAM you want to give IT. Use that as a Baseline. E.g. Server 2025 equals Win 11 and needs a fairly new CPU, use that as the Minimum for your server.

It seems even on unsupported CPU's Windows 11 24H2 and Windows Server 2025 can be installed and used without any hacks. Maybe qemu emulates the missing CPU features?

Event if it's possible to virtualize WS2025 on an unsupported CPU you should use an official supported one because of performance and Microsoft *updates*

no, qemu can't emulate missing cpu flags. (vm will not start if you choose a virtual cpu model newer than your physical cpu model)

Then the Windows 11 24H2 / Windows Server 2025 hardware requirements are not as strict as i thought ...
