Hi Thomas,
I didn't see similar error message from the compute node, where OVS
agent/libvirt/Nova-compute daemons are running.
For the network host, I did several things in the last couple of days to
address the issue:
1) switch to a new physical machine for the network host, the VM network
NIC info is now:
[root@cldnet01 bin]# ethtool -i em2
driver: bnx2
version: 2.2.3
firmware-version: 6.2.14 bc 5.2.3 NCSI 2.0.11
bus-info: 0000:01:00.1
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no
2) installed the latest version of Openstack kernel/packages from RDO on
the network host
3) noticed vlan tagging module was not loaded, so I load the 8021q
module on both the network and compute nodes
4) set use_namespace to True on both the L3 and DHCP agent config file
on network host
5) recreated the bridges (br-int/br-em2/br-ex) on the network host
Now if I only start the openvswitch daemon on the network host, the
syslog shows similar errors (and repeating it...), but after the
quantum-openvswitch-agent daemon starts,
the error message stops. Below after my signature is the snippet from
the syslog.
Now if I start an instance, its eth0 still can't get an IP.
Any wisdom on what's going on ?
Thanks,
Xin

If you are running the stock RedHat kernel not the patched version that
comes with RHOS or RDO that might explain it.

Hi Thomas,
Thanks for the reply, here is the info of the drivers:
1) NIC for the VM network connection:
$> ethtool -i eth1
driver: e1000e
version: 2.1.4-k
firmware-version: 1.6-12
bus-info: 0000:04:00.1
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes

e1000e is a driver that is known to work. The error would indicate a
silicon or firmware issue. Are you seeing this issue on multiple
machines?
