host - fedora 23 kernel 4.5.5

guest OS is FreeBSD9.3 and VF driver for FreeBSD is 1.2.11(latest).

ixlv7: mem 0xfebd0000-0xfebdffff,0xfebfc000-0xfebfffff at device 17.0 on pci0

I have configured 2 ports each with 4 VF so in total i am getting only ~100Mbps which way less than what i get from virtio.

My performance per VF is ~10Mbps and 4 VFs are getting only 40Mbps/port however i am providing close to 2.5Gbps pcap

Also i have upgraded firmware to latest, 5.04

[73053.043664] i40e 0000:aa:00.3: fw 5.0.40043 api 1.5 nvm 5.04 0x800024da 0.0.0

is there anything i am doing wrong? What's official/profiled per VF performance in the guest.

Thank you in advance

Hi Chintu,

 

 

Thank you forr the post. I can see you are using the latest VF 1.2.11 at https://downloadcenter.intel.com/download/25161/Network-Adapter-Virtual-Function-Driver-for-40-Gigab...

 

 

What is the switch model used? Have you check also on the switch setting?

 

 

I will further check on your inquiry.

Hi Chintu,

 

 

Please help confirm if you are using X710 or XL710 network adapter?

 

 

You may refer to the correct driver for X710 server adapter under FreeBSD*:

 

 

Network Adapter Driver for PCI-E* 10 Gigabit Network Connections under FreeBSD*:

What is the switch model ?

wb,

for X710 cards,

i tried using if_ixv.ko in FreeBSD guest.

8 1 0xffffffff81a6d000 1baa0 mrsas.ko

9 1 0xffffffff81a89000 390c8 if_ixv.ko

and KVM host has

[root@localhost vcr]# modinfo i40evf

filename: /lib/modules/4.5.5-201.fc23.x86_64/kernel/drivers/net/ethernet/intel/i40evf/i40evf.ko.xz

version: 1.5.14

after that i can't even see any interface detected in my VM.

[root@App46005 ~]# ifconfig

vtnet0: flags=8843 metric 0 mtu 1500

options=6c03bb

ether 52:54:00:30:a0:c0
