The configure and close operations may be called a lot of time by vhost library according to the virtio connections in the guest. VAR is the device memory space for the virtio queues doorbells. Each VAR page can be shared for more than one queue while its owner must synchronize the writes to it. The mlx5 driver allocates single VAR page for all its queues. Therefore, it is better to allocate it in probe device level instead of creating and destroying it per new connection.
