Can you also tell us the version numbers for your Xen/KVM and OVS?

packets when using with openvswitch
Hi Todd,
Please find below the details of the configuration.
openVSwitch config:
[root@XXX ~]# ovs-vsctl show
3c55434d-c453-49e9-884d-e4fd6d614606
Bridge OVS-VlanBridge
Port OVS-VlanBridge
Interface OVS-VlanBridge
type: internal
Port "vnet366"
tag: 5
Interface "vnet366"
Port "eth1"
trunks: [5]
Interface "eth1"
The Vlan is intended to be stripped on the OVS-VlanBridge, as we don't want to
trunk it to the VM.
The vnet366 is configured as an access port on the openVSwitch and corresponds
to eth1 on the VM. On the VM the configuration is :
[root@YYY ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
TYPE=Ethernet
BOOTPROTO=static
ONBOOT=yes
IPADDR=2.2.2.2
NETMASK=255.255.255.0
The physical Ethernet Port eth1 has the following configuration on the host :
DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
The OVS successfully configures the VLAN and arp requests going out of eth1 to
the network are tagged with VLAN 5. However it does not pick up the arp
responses coming back from the other side.
Let me know if any more details are needed.
Regards,
Madhur

There aren't enough details here. Can you tell us the exact steps you used for
configuring the VLANs on the host and guest?
Thanks.

Subject: [E1000-devel] igb 5.0.3-k driver doesnt pick up vlan tagged packets
when using with openvswitch
Hey Guys,
It seems there is an issue with the igb drivers not being able to receive VLAN
tagged traffic when used with openvswitch.
I am on Centos 6.5 with the following kernel:
3.10.51-1.el6.elrepo.x86_64
I have the following intel driver in my setup.
[root@XXX ~]# ethtool -i eth1
driver: igb
version: 5.0.3-k
firmware-version: 1.80, 0x00000000
bus-info: 0000:05:00.1
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no
[root@XXX ~]# lspci | grep Ethernet

I use eth1 on the DOM-0 for physical connectivity to my vm via openvswitch
and an ip address is configured on the vm. When I try to ping another machine
in the same network with vlan 5 , it seems that the arps are going out but the
nic doesn't pick up the returning arps even though the other end is duly
replying to the arps.
[root@XXX ~]# tcpdump -i eth1 -ne arp
tcpdump: WARNING: eth1: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes

I can see the arps being responded to on the other end. Can you guys help with
this?

Madhur
