Some random notes on trying (and failing) to get Proxmox as host with 5700G APU GPU PCI Passthrough to Ubuntu guest VM working:

Proxmox with LVM-thin and why we should use Trim/Discard

Excerpts from the Proxmox VE Administration Guide]

LVM normally allocates blocks when you create a volume. LVM thin pools instead allocates blocks when they are written. This behaviour is called thin-provisioning, because volumes can be much larger than physically available space.

8.10.2. Trim/Discard It is good practice to run fstrim (discard) regularly on VMs and containers. This releases data blocks that the filesystem isn’t using anymore. It reduces data usage and resource load. Most modern operating systems issue such discard commands to their disks regularly. You only need to ensure that the Virtual Machines enable the disk discard option.

Running Plex in an Unprivileged LXC with Intel QuickSync Passthrough

First setup an unprivileged Ubuntu container with Plex Media Server installed. Inside the container take note of the id of the plex group.

# Your Plex group's ID may be different
$ getent group plex | cut -d : -f3

Instructions taken from https://forum.proxmox.com/threads/lxc-usb-passthrough-zwave-stick.30058/ and addtional information added for clarity.

1. Plug in you USB ZWave stick and find the Major:Minor Numbers:

root@proxmox01:~# lsusb
Bus 004 Device 005: ID 0658:0200 Sigma Designs, Inc.

Major Number is 4, Minor is 5 for me (Bus and Device). Yours will vary.

Netcat is like a swiss army knife for geeks. It can be used for just about anything involving TCP or UDP. One of its most practical uses is to transfer files. Non *nix people usually don't have SSH setup, and it is much faster to transfer stuff with netcat then setup SSH. netcat is just a single executable, and works across all platforms (Windows,Mac OS X, Linux).

On the receiving (destination) terminal, run:
