Proxmox VE - Backup Cluster config (pmxcfs) - /etc/pve

Backup

A no-nonsense way to safely backup your /etc/pve files (pmxcfs) [^CFS] is actually very simple:

sqlite3 /var/lib/pve-cluster/config.db .dump &gt; ~/config.dump.$(date --utc +%Z%Y%m%d%H%M%S).sql

Docker Exploit Redirect (PS4 & PS5)

Install Docker Desktop
Change the REDIRECT_IPV4 address to your computer's IP
Change the ROOT_DOMAIN and ROOT_DOMAIN_PATH to where you want to redirect to (Change redirect type if necessary)
With Docker running run docker compose up -d from cmd in the directory with this file

This will install and start the Docker images

On your PS4/PS5 use your computer's IP for the primary DNS server. You can skip secondary or use the same IP again if you wish.

Enable & Using vGPU Passthrough

This gist is almost entirely not unlike Derek Seaman's awesome blog:

Proxmox VE 8: Windows 11 vGPU (VT-d) Passthrough with Intel Alder Lake

As such please refer to that for pictures, here i will capture the command lines I used as i sequence the commands a little differently so it makes more logic to me.

This gists assumes you are not running ZFS and are not passing any other PCIE devices (as both of these can require addtional steps - see Derek's blog for more info)

This gist assumes you are not running proxmox in UEFI Secure boot - if you are please refer entirely to dereks blog.

The following works for pve 8 with 6.5 kernel.

The driver is still experimental, use with your own discretion.

prepare env

git clone https://github.com/strongtz/i915-sriov-dkms
apt install dkms build-essential proxmox--headers-6.5

Disable & Enable MPO via the Windows Registry

There is a well known issue where GPU drivers are crashing with multi-monitor setups due to an interaction with Windows MPO and both Nvidia and AMD GPUs.

Until this bug is fixed, the only solution is to disable MPO via the Windows Registry.

Disable MPO

To apply the fix, simply run mpo_disable.reg and reboot your computer.

This is to solve an issue where you use a non-apple european keyboard with the US keyboard layout in macOS where the Tilde key is in the wrong place.

This is the process for the Logitec MX Keys Mini

Connect the keyboard (bluetooth)
Make sure the keyboard is in PC mode (hold fn + p for 3 seconds)
Go through the keyboard wizard and at the end select the European ISO... layout
Switch the keyboard to Mac mode (hold fn + o for 3 seconds)
Tilde should work

If this doesn't work:

ASUS ROG Zephyrus G14 2022 GA402RJ pci passthrough

This is a record for my own passthrough setup, I can finally use a single laptop for windows gaming and linux programming at the same time.

The device

My G14 is GA402RJ(6800HS + 6700s) with MT7922 WiFi/BT card.

At this time, BIOS version is 309.

Turn off AER logging for NVMe and event severity corrected

Motherboard: Asus Pro WS WRX80E-SAGE SE WIFI
Card: Asus HYPER M.2 X16 GEN 4 CARD
NVMe: 4x Samsung SSD 980 PRO 1TB
OS: Linux fedora 5.16.12-200.fc35.x86_64

AER, advanced error reporting logs excessively:

	1) Close Parallels completely
	2) In Terminal, type : sudo nano /Library/Preferences/Parallels/network.desktop.xml (this will open the Terminal text editor "nano")
	3) Type your admin password to access the file
	4) Locate this line <usekextless>-1</usekextless> it could be also value 1 and replace whatever value there with 0, so you should have <usekextless>0</usekextless>
	5) Press Ctrl+O to ask for a save, then Ctrl+X to close the editor
	In Terminal, type : sudo nano /Library/Preferences/Parallels/dispatcher.desktop.xml
	find <usb>0</usb> and change 0 to 1
	again Press Ctrl+O to ask for a save, then Ctrl+X to close the editor
	6) Close Terminal and open Parallels like normal, your VM should load like on Catalina and before
