We’re not quite sure what’s going on. Can you send the output of dmesg as well as “ifconfig –a” and “netstat –g”?
Keep in mind that attachments don’t work on this mailing list. If the dmesg is large, please open a bug on e1000.sourceforge.net and attach it there. Thanks.

I do see the multicast filters properly programmed (by writing to mailbox to communicate to host igb driver). Packets are not seen even if the interface is put in promiscuous mode in the guest. The only way to solve the issue is to put the physical interface (or physical function) of the corresponding VF in promiscuous mode on the host. I tried looking into in the mailing lists if any such issues are reported, but couldn't find one. Could you please let me know of any known issues with igbvf driver in handling multicast packets or is it by design that the multicast packets and the filters are not engaged in. Thank you. Regards, B Lee
