I am having hard time to get the SR-IOV to work on fc14/debian with xen 4.0.1.
I am using a xen 2.6,32-stable kernel.

I have enabled my kernel with all the default options needed for PCI
passthrough and DOM0.
When I launch a DOM-U kernel with a PF (physical function) mapped, I
can see the eth0 device I am able to us it.

But when I launch a DOM-U kernel with a VFx (virtual
function) mapped, I can see the eth0 device but cannot use it.
I cannot ping anything and it is not usable.

May be I am missing something pieces. Did anyone have a similar problem?
Am I missing a kernel option / configuration option?

I am using intel 8-port 82576(SR-IOV capable) card.

I have gone through the xen documentation and it does not start
anything about PCI passthru not working in 2.6.32. I synced up with
2.6.27 sources and found that  "drivers/xen/pciback" is missing.
When I sync to 2.6.38, I see the "drivers/xen/pciback" directory but
found that XEN_PCI_PASSTHROUGH is missing.

./arch/x86/xen/Kconfig:config XEN_PCI_PASSTHROUGH // only 2.6.32-stable branch

If I move to 2.6.38, can I expect it work better? The primary target I
have now is to get the PCI pass-through working.
