hi, I have report bug on sourceforge,
They was replay me this message
"Please contact proxmox as this appears to be a kernel error."

That, I will try to clarify the issue there. Please can you test if setting the suggested module flag work?
In /etc/modules, set

igb max_vfs=2,2

Hi, igb sriov is very Important for me.
If I am try igb after, I'll post reply on this


but I'm try my X552, It's different is X552 use ixgbe driver
I think is maybe the same problem

this is my friend help me to post this

openvswitch-switch: 2.3.2-2
on proxmox-ve: 4.1-41 (running kernel: 4.2.8-1-pve), I can do SR-IOV in my intel i-350(use igb)

Code:
root@pve:~# modinfo ixgbe |grep vf
parm:           max_vfs:Number of Virtual Functions: 0 = disable (default), 1-63 = enable this many VFs (array of int)
root@pve:~# modinfo igb |grep vf
parm:           max_vfs:Maximum number of virtual functions to allocate per physical function (uint)
I try to compiler new ixgbe driver, but SR-IOV It's not work
after sourceforge reply, I'm try to do ixgbe SR-IOV

command is this, then I can use SR-IOV in X552
Code:
rmmod ixgbe
modprobe ixgbe max_vfs=4,4

I assume the file /sys/class/net/eth0/device/sriov_numvfs does not exist?
Yes, It's not exist.

Hello, I know how to do SR-IOV...
I tried/etc/modules, set igb max_vfs=2,2 but didn't work, but it hints me towards another direction make it worked.

I used following setting and made intel i350 sr-iov enabled.
Code:
echo "options igb max_vfs=2,2" > /etc/modprobe.d/igb.conf
depmod -a
update-initramfs -u
Then Reboot

Code:
root@pve:~# lspci |grep Eth
03:00.0 Ethernet controller: Intel Corporation Ethernet Connection X552/X557-AT 10GBASE-T
03:00.1 Ethernet controller: Intel Corporation Ethernet Connection X552/X557-AT 10GBASE-T

thanks for all the helps
