Hello,
I installed kvm and tried to use SR-IOV virtualizaton for 82599EB(Intel XT-520 T2) dual port card with latest ixgbe driver(version:3.11.33) ,
kernel2.6.32-279.14.1(OS:Centos6.3) ,after configuration and reboot
It seems that only first port of the card's VFs works,second port of the card's VFs didn't work
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
How to fix it,any help would be greatly appreciated.
below is the related information:
