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

Hi,
I am installing perl and rsnapshot on the OS of a Western Digital MyBook disk.
To install perl the ./Configure command tells me that both 'tr' and 'split' are missing. I don't find them on the net.
Where can I download them?
Thanks.

In linux 3.0.4, can "netif_queue_stopped" function check wether or not the net device queue is stopped? How could I know wether a net device queue is stopped or not?

hv_utils
HYPER-V(4) BSD Kernel Interfaces Manual HYPER-V(4)NAME
hv_utils -- Hyper-V Utilities Driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in the system kernel configuration file:
device hyperv
DESCRIPTION
The hv_utils driver provides time keeping, shutdown and heartbeat functionality for FreeBSD guest partitions running on Hyper-V. Hyper-V is
a hypervisor-based virtualization technology from Microsoft. The hv_utils driver is one of the core drivers required to be present in guest
partitions running on Hyper-V. This driver provides the following functionalities to guest partitions:
(a) Time Keeping: The clock inside the guest partition will remain accurate by synchronizing to the clock on the virtualization server via
Timesync service, and with the help of the pluggable time source device.
(b) Integrated shutdown: Guest partitions running FreeBSD can be shut down from Hyper-V Manager console by using the "Shut down" command.
(c) Heartbeat: This feature allows the virtualization server to detect whether the guest partition is running and responsive.
SEE ALSO hv_ata_pci_disengage(4), hv_netvsc(4), hv_storvsc(4), hv_vmbus(4)HISTORY
Support for hv_utils first appeared in FreeBSD 10.0. The driver was developed through a joint effort between Citrix Incorporated, Microsoft
Corporation, and Network Appliance Incorporated.
AUTHORS
FreeBSD support for hv_utils was first added by Microsoft BSD Integration Services Team <bsdic@microsoft.com>.
