Hetzner EX series (Intel) and virtualization

As EX-44 come with Intel Core i5-13500 which have 6 P-core and 8 E-core the price/performance is very lucrative to opt-in even with ECC addon added.

Do anyone uses proxmox on this CPU???, can proxmox handle both P & E cores also what about iGPU, does it work properly with passthrough?

What about performance in compare with AMD Ryzen 5 3600 come with AX-41 and cost cheaper.

    iGPU should work via SR-IOV but it's kind of a recent thing: https://www.michaelstinkerings.org/gpu-virtualization-with-intel-12th-gen-igpu-uhd-730/

    Before 11th gen, there was GVT-g.

    Anyway, Proxmox works fine on intel 12th and 13th gen CPUs, as long as you use a kernel version of 6.2 or higher. I have been told that kernel 6.1 onward supports P and E core CPUs, but since you need to update, might as well update to 6.2 or higher... Proxmox comes with Kernel 5.15 (i think) so if you do not know how to build/install PVE kernel 6.2, skip proxmox.

    Although there seems to be no issues with P and E cores, igpu MAY have issues.

    Best way to avoid these issues is to install debian on the server, followed by proxmox installation on debian, instead of installing proxmox from ISO.

    @Not_Oles was running VMs on Intel 13900K so if you are able to run VM, proxmox can manage it as well.

    Hi @hostaspace and @somik,

    To control Performance and Efficiency Cores on 13th Gen as in EX44 and EX101 from Hetzner, Intel has "Thread Director." There is a description of Thread Director in How 13th Gen Intel® Core™ Processors Work.

    Intel submitted Linux kernel patches for "Thread Director." The initial set of Thread Director patches might be here.

    The integrated graphics is a separate question from the fast and slow cores. My EX101 seems to have been received from Hetzner without integrated graphics enabled. I'm unsure whether disabled iGPU is a motherboard default or whether Hetzner turns off iGPU, but I have just started reading the motherboard manual in preparation for trying to enable the graphics and maybe do some OS installs. I don't know if the EX44 uses the same motherboard, but my EX101 has an ASRock Rack W680D4U. This motherboard's instructions may be found at https://www.asrockrack.com/general/productdetail.asp?Model=W680D4U#Specifications.

    Passthrough is something I haven't yet looked into very much. VMs seem to run fine under Debian sid, but I haven't yet tried to enable passthrough. Here is some iGPU info from my EX101 which is running Debian sid, not Proxmox:

    Proxmox uses an Ubuntu kernel and a Debian userland. Last time I checked, Proxmox had a precompiled, newer Ubuntu kernel version available in Proxmox' Github repo, so maybe you could use that if they're still making the new version available. Or, of course, you can compile your own kernel.

    Hetzner has a really cool, fast "Proxmox on top of Debian" install via Hetzner Installimage. Here is a tutorial about Proxmox via Installimage.

    As I'm sure you both know, there is a new Debian release just out and also a new Proxmox version to go with the new Debian.

    Good luck!

    PVE 8 (now in beta) ships with Linux 6.2 by default. In any case, you can also install the 6.2 opt-in kernel on PVE 7.

    Thanks for the update. With the commands mentioned, it should be very easy to install PVE Kernel 6.2 on current gen proxmox to use with Intel 12th and 13th gen CPUs.

    apt update
apt install pve-kernel-6.2
reboot
