The little mini-pc I'm using to test Proxmox unfortunately only has a single 1gb ethernet port. Since most of my network is 10 gig, I decided to see if I could at least get 2.5 gig working, since this box doesn't have thunderbolt and those adapters are super pricey anyways.

I picked up this Anker adapter from Amazon: Anker USB C to 2.5 Gbps Ethernet Adapter

All I had to do was plug it in and create a bridge with it within Proxmox. I assigned an adapter to my Windows host (using the VirtIO Paravirtualized driver) and installed the driver from the Qemu guest agent ISO:

PVE.PROXMOX.COM "https://pve.proxmox.com/wiki/Qemu-guest-agent"

Qemu-guest-agent - Proxmox VE

And that was that. I now have 2.5 gig ethernet for Proxmox!

@malcolm-r Thank you for testing the USB-C to ethernet adapter. This will be a great resource for those looking to add 2.5 GbE to their mini PCs. I am assuming this is a realtek chipset like my 1 gig adapter, so should work (ironically) with VMware as well.

@malcolm-r are you starting to run more workloads in Proxmox for testing? Curious how you are liking it?

@brandon-lee not a ton, yet. with 2 big esxi hosts i just don't have a big use case right now. i am, however, about to spin up an Ubuntu VM to transfer my torrent client to. i'm seeing some performance issues running it in docker, so i'll try a VM next and see if that helps.
