Preface: Inspired by the lack of patches for this new ThreadRipper CPU series , I have started to find a way to have "the fast Amd hack ever". Hard task was to setup a pretty bare machine inside an OSX linux vm. Many solutions were evaluated to reach this important goal. Ubuntu, CentOS, UnRaid and so on Tested many VM and found many interesting stuff on the net. Kholia's or foxlet's GitHub guide for example or nicksherlock's guide more Proxmox like. With these guide is possible to start our job and to have a working OSX..but I need more! 😉 I want to use my single Nvidia Gpu on it and for it I need a different approach. Single GPU usually is a pain because when we passthrough* it to the guest PC..we will loose it. So, we have to use another PC to connect in it or a simple Android or iOS tablet (now I am use my iPhone for this task 🙂 ) So, after some days of brainstorming with @tomnic we choose to start with Proxmox VE. It seemed the most flexible linux distro to reach my goal. macOS High Sierra and Nvidia web driver installed with no compromise. Proxmox Ve allows to build a bare metal system with Gpu passthrough, and, most important thing it has a web interface to control guest PC * Passthrough is a technique to "pass" hardware to a virtual machine loosing only a minimal part of hardware performance More difficult and critical task is passthrough our hardware to VM in a way which will allow me to have a pretty similar performance as a real hack and overall to have GPU at its best in this system. Prequisites: A minimal linux experience (I have had no idea before about linux and this was the main difficulty for me) To know what to search usefull for my need! A OSX, linux or windows system to collect some files (I have used used linux and OSX, with latest one preferred. System configured is in my signature, summarized here: MSI Trx40 10G Pro AMD 3970x Threadripper 32 cores / 64 threads (this guide is also useful for 3960x and maybe for 3990x (capping cores not supported by OSX kernel) 1Tb Nvme Sabrent and so on... Let's start! Mandatory Elements: 0) Proxmox VE (Proxmox Ve's wiki link) 1) a working OSX. Linux, Windows ( in this guide we use OSX High Sierra 10.13.6 2) download Vm_assistant's script, an exclusive script by macOS86.it and @Gengik84 VM assistant From this link a simple guide: Promox VE installation procedure: In this guide I will not do a detailed guide to install this linux release, you can find useful information on: link to Proxmox link to iso installer Use your favorite Iso installer to produce a bootable USB pen drive (8gb or more is fine) In this guide I have used Balena Etcher: link Balena Etcher Warning for initial installation part! * Due a problem with new TRX40 motherboard , ProxMox 6.1 and lower will hang on early booting stage. To avoid this you have to modify grub.cfg file in this way: find this line: linux /boot/vmlinuz-5.3.10-1-pve root=/dev/mapper/pve-root ro quiet with this linux /boot/vmlinuz-5.3.10-1-pve root=/dev/mapper/pve-root ro quiet mce=off adding mce=off allows us to start this exciting journey.... Alternatively you can modify this line directly on boot menu selection before selecting your choice (press E and add mce=off as shown before) thanks @KTC for pointing me in the right direction * this problem could be resolved with a future Proxmox update SOLVED in Proxmox 6.1-3 and greater step 1: boot from your ProxMox Ve USB pen drive, you will have: select Install Proxmox VE and then follow indication you can see below. Note Fill your network data with your (setup should do it for you except for Domain and your email) Installation is done! 😛 Reboot and choose your usb pen drive and boot from it. In a few second you will see: Now pay attention..if you have not modified grub.cfg...you MUST do it now pressing E on keyboard and adding manually mce=off as previously shown. You have also to remember to do it permanently when we start in Proxmox VE first time. At login user is root password (your previous choice during Proxmox installation) now it is possible to be a bit worried..if you are (as I was) not confident with linux command)..but I will try to stay more simple I can. Start to find googling how to read or to modify some files in linux (text configuration file I mean). I have used nano command..you can also use vim or similar command. Now, take note of link you can see in this picture: https://192.16.1.92:8006 (yours could be different) and the magic starts : )
