Problem with assign SR-IOV Intel NIC to QEMU Virtual Machine.

Hello,

I am using an Intel 82599 NIC and would like to use the SR-IOV function to assign the virtual functions to my virtual machine. I actually follow the on-line Intel document to add the "max_vfs=2" parameter when the ixgbe module is loaded. I can see the virtual function of NIC by now:

and the "ip link show" gives me following result (I remove the kernel module ixgbevf):

vf 1 MAC 00:00:00:00:00:00, spoof checking on, link-state auto

But when I try to assign the virtual function(PCI dev assign) to my virtual machine, the virt-manager gives me following error:

Error starting domain: internal error: qemu unexpectedly closed the monitor: 2016-08-26T15:39:40.880928Z qemu-system-x8...

Hi enigma_lee,

 

 

Can you help provide further info using the ethtool -i output for us to identify the PF and VF driver loaded and the Linux OS version.

 

 

Thanks,

Intel Xeon E3-1200 v3/4th Gen Core Processor lacks necessary features to support SR-IOV use case. Intel Xeon E5 Processors are recommended for SR-IOV use case.
