    82599EB,not enough MMIO resources for SR-IOV,Centos6.3

    syscall

      Dear All,

       

      I'm using latest version of ixgbe , ixgbevf  and want to use SR-IOV function with xt-520 T2(dualport),but when I try to load ixgbe driver with this command:

      #modprobe ixgbe max_vfs=2,2

      It seems that only first port of the card's VFs works,the problem is second port of the card's VFs didn't work, and I found some errors in /var/log messages:

      Nov  8 14:56:54 12 kernel: ixgbe 0000:07:00.1: not enough MMIO resources for SR-IOV

      Nov  8 14:56:54 12 kernel: ixgbe 0000:07:00.1: (unregistered net_device): Failed to enable PCI sriov: -12

       

      Any help would be greatly appreciated.

       

      below is the related information:

          Patrick_Kutch

          Thanx for coming to our forum and using Inel Ethernet.

           

          Generally whenever we hear about lack of MMIO space, it is almost always the BIOS.  I've done lots of SR-IOV on R710's and Intel 82599 10GbE devices.

           

          You seem to have all the latest goodies - PF and VF driver.

           

          The only variable in here that I've not used is your OS.  I've never touched centos.  Can you try install RHEL 6.2 and give it a try?  Let's remove all unknown variable and see if we can figure it out.
