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 commented 12 months ago

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.
