-== Use multiple queues for your VirtIO network interfaces
-
-With multiple virtual CPUs, you can transfer packages in parallel if you provide multiple queues for incoming and outgoing packets. Use the `queues` attribute of the `driver` element to configure multiple queues. Specify an integer of at least 2 that does not exceed the number of virtual CPUs of the virtual server.
-
-The following example specification configures two input and output queues for a network interface:

-<interface type="direct">
-    <source network="net01"/>
-    <model type="virtio"/>
-    <driver ... queues="2"/>
-</interface>

-Multiple queues are designed to provide enhanced performance for a network interface, but they also use memory and CPU resources. Start with defining two queues for busy interfaces. Next, try two queues for interfaces with less traffic or more than two queues for busy interfaces.
