Proxmox on older systems

[cshill]

Good Morning/Evening,

Windows 11 has certain requirements that must be met in order for the OS to be installed. I can force a Windows 11 installation on metal or virtually but is there something within Proxmox that would make this more secure? Am I going to run into the same security vulnerabilities running the Windows 11 VM on Proxmox as I would bare metal? If there is a vulnerability then shouldn't I also only have Proxmox running off of the CPU requirements for a Windows 11 machine?

I know Ubuntu24 isn't asking me for the same requirements but am I fundamentally hurting myself by running Ubuntu off of an Intel I5-3rd gen with DDR3 ram?

Run lscpu [1] on your system and see what the kernel mitigates. Running some old systems directly on that hardware is like running modern kernel with mitigations=off [2]. Running it in virtual environment you have it sandboxed. See also e.g. thread on QEMU [3].
