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.

Physical functions seem to work fine - interface in HVM guest has full network access. Virtual function does not work. DHCP reqests from guest HVM are received at the DHCP server, responses are returned, but the HVM never receives them. -David _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
