Hi all,

 

I am trying to get sriov working with Mellanox. I have KVM hypervisor, and I have 2 port Mellanox cards. I am using port 1 of all cards.

This is my output of lspci | grep Mel

When I bring up a vm through an xml file, whatever mac address is specified in the xml file gets assigned to the vf of port 2 instead of being assigned to vf of port 1. shouldn't it get assigned to the vf of the physical port that is in use? I have to do an ip link set manually on the correct ports vf to get it working
