I got an Intel N100 machine from Changwang.
It has 4x 2.5Gbps i226-V ethernet cards.
I installed a 32GB DDR5-5600Mhz RAM on it. CPU N100 supports upto 16GB RAM according to Intel's site but the 32GB ram works fine though it works at 4800Mhz.
I installed a PVE from a USB drive burned with PVE 7.x. Installing PVE is very easy. So here I won't address.
I used a NVME Sandisk SN550 drive (a previous version which supports 2400MB/s writes and 800MB/s writes after using up SLC cache)
PVE 7.x comes with linux kernel 5.15.x derived from Ubuntu 22.04 which doesn't support i226-V drivers. So I upgraded the Linux Kernal to 6.1.x in the PVE 7.x manually.
There is a tutorial which teaches people to install a Windows 10/11 VM on PVE and enable Intel UHD Integrated GPU passthrough.
Tutorial (in Chinese): https://www.youtube.com/watch?v=dBI4YGKAwGg
The key of passthrough is that you have to use i915-sriov drivers with Linux kernel 6.1.x. You can find helpful information from this GitHub repo: https://github.com/strongtz/i915-sriov-dkms (Read the docs carefully if you want to use it).
What is SR-IOV?
For example, you have 1 ethernet card, and you want to create 3 VMs which uses the same ethernet card. We can use SR-IOV create 3 virtual ethernet cards so that each of the VM can get a virtual ethernet card. With 1 ethernet cable, all 3 VMs can share the bandwidth of the real ethernet card. It's the same for Integrated card. Nvidia has the same technology which is called vGPU.
To benifit from PVE's high speed passthrough between VMs, it's recommended to use VirtIO drivers both in PVE and your windows/linux VMs.
I tested the performance of the Windows 11 VM which has a Intel UHD graphics card being passthroughed, it can play YouTube 4K60FPS VP9 videos smoothly. Also it can play 8K 60FPS AV1 video from YouTube which is amazing thought the GPU (decode) usage reached 98%, almost 100%. And it can play lite games.
