After installing on a fresh installation of ubuntu 22.04
libreqos is not working due to an error

You need a network card that supports multiple Rx/tx queues.

@thebracket Thanks for reply my question

I install Ubuntu in QEMU (GNS3 with virtio nic for lab testing) and I've seen server requirements that say
"Using Virtio / bridging is much slower than NIC passthrough. Virtio / bridging should not be used for large amounts of traffic."

Is virtio nic still support ?

[thebracket]

Virtio works, but you have to configure it to have multiple tx/rx queues. It's not as fast as passing through an actual NIC, but it does work.
