I currently have an Ubuntu Server 24.04 VM using VirtIO with a Linux bridge. I am unable to get this ubuntu vm to recognize the virtio interface as 10G. Ethtool won't even display for the virtio interface. Am I missing a driver of some sort?

Well... it is a virtual device. Capabilities reported may be different than the hardware implements.

Did you actually try to transfer more than 1 GBit/s? Give it a try - using iperf3 for example.
 
Hello, i try it yesterday by my self, on my mini nas with Ryzen 5 3500X cpu, ASRock B550M Mainboard with 32 GB Ram and as storray i use ZFS: 2x ssd (rpool) and 2x ssd (special device, zil/log)+ 2x hdd Harddisk (dpool).
The installation on a VM work fine with 4 CPU Core and 6 GB Ram.
I use SDN Nat on SimpleNetwork for this client only test setup.
I Have 2 real network connections for Management 1 GBit/s and 2.5 Gbit/s Dataaccess.

Maybe you must install qemu-guest-agent, so you can easy use all feature von Promox VE, KVM:
