[Xen-users] Trace SRIOV NIC's MSI-X delivery to Xen

[Manish Verma <manish.verma@xxxxxxxxxxx>]

Hi all,

I'm using Xen4.0.1 with SLES11SP1  with Intel's SRIOV NIC in passthrough 
mode to FedoraCore14 guest HVMs.
From guest HVM I'm able to send packets out but not able to receive the 
same.
Intel NIC HW counters are reporting receiving packets but  the same is 
not reaching the guest HVM.
My NIC uses MSI-X to report packets to SW. which should be received by 
Xen and forwarded to HVM guest where I don't see relevant 
/proc/interrupts counter ticking.
Thus I would like to trace whether MSI-X requests are reaching Xen. Any 
known xen command to trace the same.
Thanks in advance.

Best regards,
Manish
