Multi-Queue virtio-net Functionality in Linux
It seems that multi queue virtio functionality is enabled in the Redhat System being used, but I need to confirm if this functionality is working appropriately:

Code:
cat /usr/include/linux/virtio_net.hstruct virtio_net_config

{ /* The config defining mac address (if VIRTIO_NET_F_MAC) */ __u8 mac[6]; /* See VIRTIO_NET_F_STATUS and VIRTIO_NET_S_* above */ __u16 status; /* Maximum number of each of transmit and receive queues; * see VIRTIO_NET_F_MQ and VIRTIO_NET_CTRL_MQ. * Legal values are between 1 and 0x8000 */ __u16 max_virtqueue_pairs; }

_attribute_((packed));

I want to test below scenarios:

The guest is active on many connections at the same time, with traffic running between guests, guest to host, or guest to an external system.



Also is there any other way to check if Multi-Queue virtio-net Functionality is functioning appropriately
