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

PAM_GUEST(8)						    BSD System Manager's Manual 					      PAM_GUEST(8)

NAME
pam_guest -- Guest PAM module SYNOPSIS
[service-name] module-type control-flag pam_guest [arguments] DESCRIPTION
The guest service module for PAM allows guest logins. If successful, the pam_guest module sets the PAM environment variable GUEST to the login name. The application can check this variable using pam_getenv(3) to differentiate guest logins from normal logins. The following options may be passed to the pam_guest module: guests=list Comma-separated list of guest account names. The default is ``guest''. A typical value for ftpd(8) would be ``anonymous,ftp''. nopass Omits the password prompt if the target account is on the list of guest accounts. pass_as_ruser The password typed in by the user is exported as the PAM_RUSER item. This is useful for applications like ftpd(8) where guest users are encouraged to use their email address as password. pass_is_user Requires the guest user to type in the guest account name as password. SEE ALSO
pam_get_item(3), pam_getenv(3), pam.conf(5), pam(8) AUTHORS
The pam_guest module and this manual page were developed for the FreeBSD Project by ThinkSec AS and NAI Labs, the Security Research Division of Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the DARPA CHATS research program. BSD
