*Hello,*
I have gone through couple of mail chains with the same problem title, but
still I am out of clue, I have tried all of what is mentioned.
1. I am using Intel i-7 WX58BP Motherboard, with Intel 82576 Quad Port
SR-IOV NIC attached to x-16 PCI Express slot.
2. I am booting my Dom0 using following:
title Xen -- openSUSE 11.4 - 2.6.37.6-0.11 SR-IOV
root (hd0,6)
kernel /boot/xen.gz vga=mode-0x317 iommu=1 msi=1 pci=assign-busses
module /boot/vmlinuz-2.6.37.6-0.11-xen
root=/dev/disk/by-id/ata-ST31000528AS_9VP9NG6C-part7
resume=/dev/disk/by-id/ata-ST31000528AS_9VP9NG6C-part5 splash=silent quiet
showopts vga=0x317 pci_pt_e820_access=on
3. dmesg shows following about SR-IOV
[ 5.839750] igb 0000:05:00.0: SR-IOV: bus number out of range
[ 6.029886] igb 0000:05:00.1: SR-IOV: bus number out of range
[ 6.221602] igb 0000:06:00.0: SR-IOV: bus number out of range
[ 6.413736] igb 0000:06:00.1: SR-IOV: bus number out of range
4. ifconfig shows eth1, eth2, eth3 and eth4 corresponding to 4 physical
ports.
5. It doesn't show VFs
cadlab:/boot/grub # lspci | grep Eth
