I'm trying to setup some X520-DA2s with one copper cable and one Intel
LR SFP in each for standard PF PCI device pass through. The same systems
are working OK with virtual function pass through of 82576 ports so I
think the Xen configuration is fine. The 82599EB works correctly in
Dom0, appears in pci assignable devices when hidden and is set as
permissive in pciback. All messages in Dom0 seem encouraging but the
paravirt Domu just gives error -5 when using the 3.2.10 driver or the
Redhat supplied drivers. Kernel is RHEL 2.6.18-247.
Can anyone help with what error -5 means? Or does anyone know of
something specific that needs to be done to make pass through of the
82599EB work?
Thanks,
Rob
