Multiqueue Option for Virtio NIC - how to enable in OPNsense?

[OpenNonsense]

Hi,

I'm currently in the process of setting up OPNsense on my server for inter-VLAN firewalling. Traffic is on a 2x10 Gbit bond, so I'm trying to use the multiqueue option of OPNsense. Documentation says, that multiqueueing needs to be activated also within the VM. This is not possible pfSense, as they opted for ALTQ instead (see https://forum.netgate.com/topic/159665/multiqueue-on-virtio-nic and https://forum.netgate.com/topic/138174/pfsense-vtnet-lack-of-queues/4). However, I've read that people are using it for OPNsense, but I can't find how to.

Any helpful hint would be appreciated!

Although the thread is quite old, I only activated multiqueue on the host side - that's it.
On Proxmox you can achieve this via the GUI (Network Device - Advanced). Result of 4 queues on Proxmox host in OPNsense guest:
