    Unable to receive packets at VF in VM

    Weirong

      Hi,

       

        I have two Niantic (82599) ports (eth1, eth4) in a Romley board. The ports are connected with an Ixia traffic generator through fiber cable.

       

        Following the technical brief, I created one Virtual Function (VF) for each Niantic port. Both VFs were assigned to the VM.

       

        Inside VM, both VFs (eth1, eth2) were up and running.

      eth1  Link encap:Ethernet  HWaddr 4A:48:46:DB:F4:B7
            inet6 addr: fe80::4848:46ff:fedb:f4b7/64 Scope:Link
            UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
            RX packets:0 errors:0 dropped:0 overruns:0 frame:0
            TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
            collisions:0 txqueuelen:1000
            RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

       

      eth2  Link encap:Ethernet  HWaddr DE:4C:D3:32:2D:9E
            inet6 addr: fe80::dc4c:d3ff:fe32:2d9e/64 Scope:Link
            UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
            RX packets:0 errors:0 dropped:0 overruns:0 frame:0
            TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
            collisions:0 txqueuelen:1000
            RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

       

       

      [root@vm-fedora14 ~]# ethtool -i eth1

      driver: ixgbevf

      version: 2.6.2-NAPI

      firmware-version: N/A

      bus-info: 0000:00:07.0

      supports-statistics: yes

      supports-test: yes

      supports-eeprom-access: no

      supports-register-dump: yes

      [root@vm-fedora14 ~]# ethtool -i eth2

      driver: ixgbevf

      version: 2.6.2-NAPI

      firmware-version: N/A

      bus-info: 0000:00:08.0

      supports-statistics: yes

      supports-test: yes

      supports-eeprom-access: no

      supports-register-dump: yes

       

      Then I configured the IP addresses for them: 192.1.1.1 and 192.2.1.1.

       

      Finally I sent the traffic from Ixia to 192.1.1.1 and 192.2.1.1. But no packets reached the VFs. On the other hand, "tcpdump" showed that the PFs in Dom0 were receiving the packets.

       

      Did I miss any thing?

       

      Thanks.
