I'm looking for help and advice. Click images to see larger version.
I have a little experience operating Proxmox VE on servers — which belong to clients. But, they are running older versions. Mostly, I just interact with the Linux guest VMs (Virtual Machines) hosted on Proxmox.
In the past, I have seen YouTube videos touting, "I run Linux, macOS, and Windows — on one machine, simultaneously — with Proxmox!" Typically, however, the YouTuber is running Proxmox on a desktop PC — with a workstation CPU (Threadripper or Xeon W) — and at least 2 graphics cards. At least one of the graphics cards is an AMD Radeon — for PCI-passthrough to the macOS guest VM.
My goal is to build a portable virtual environment. To work with, I only have 2 graphics devices — Intel 13th-gen integrated-graphics and NVIDIA RTX 4060 discreet-graphics. Except on standby, the system guzzles battery. I don't expect to run this without the power supply (available). Power concerns aside, I suspect I can run (at most) 2 VMs to 2 displays — including (or in addition to) the built-in display. As I don't want to rely on another device to manage Proxmox, I am aware I will need to install a (light) desktop environment.
My major concern are the IOMMU groups for PCI-passthrough. The RTX 4060 is definitely in a discreet group — to pass through to Windows or Linux. But, macOS will only work with Intel or AMD graphics (or very old NVIDIA cards). In the past, I have run Mojave on a guest VM in VirtualBox — on a Lenovo 2-in-1 (Intel 8th-gen Core i7 + NVIDIA MX230). I did not find a way to pass through the Intel integrated-graphics. Nor did I find a way to output sound.
I hope I have better luck with KVM and qemu.
Another concern is BIOS updates. I haven't had to download a BIOS-update and run it from boot-media in over a decade. Nor have I checked if that is still possible. I see that I can download a BIOS update (.exe) from Lenovo Support. But, can I run the update without Windows? Although I plan to have a Windows VM, I don't plan to use the OEM (bare metal) Windows system.
I have already backed up the initial state of the SSD. So far, I have been using the Legion Pro 5i Gen 8 — solely with Linux Live-USB. Here are the Geekbench 6 results (links launch new tab or window):
- Geekbench6 results on AC-power: 2,781 (single) and 14,969 (multi)
- Geekbench6 results on DC-power: 2,745 (single) and 12,993 (multi)
I don't know if this can be done. A few years ago, I was excited to try. But, much has changed.
Once more... I am looking for help and advice. Thanks in advance!
