Hello guys,
I am trying to run tests in an environment with 2 machines. The first
contains Openstack Queens, networking-odl, networking-sfc and OpendayLight
Oxygen (Karaf 0.8.1). The second, the computing host, stores the VMs and
has Openvswitch 2.6.1 (with NSH).
In the computing host there are 3 VMs: SRC, DST, and SF1 (with Port1 and
Port2 ports) as the network settings below:
SRC - 10.0.0.8 - (fa:16:3e:ae:ab:12)
DST - 10.0.0.4 - (fa:16:3e:14:a2:a7)
Port1 - 10.0.0.7 - (fa:16:3e:29:84:02)
Port2 - 10.0.0.6 - (fa:16:3e:93:4e:a9)
To enable SFC, the following commands have been successfully executed:
- openstack sfc port pair list
-openstack sfc port pair create --ingress port1 --egress port2
--service-function-parameters correlation=nsh PP1
-openstack sfc port pair group create --port-pair PP1 PPG1
-openstack sfc flow classifier create --ethertype IPv4
--source-ip-prefix 10.0.0.8/32 --destination-ip-prefix 10.0.0.4/32
--logical-source-port 7ee176cf-bfe2-4cd5-808c-f6882835c519 --protocol tcp
--destination-port 12345:12345 FC1
-openstack sfc port chain create --port-pair-group PPG1 --flow-classifier
FC1 --chain-parameters correlation=nsh SF1
However, after trying to communicate between SRC and DST (passing through
SF1), nothing happens. And the following error appears in the Openvswitch
log of the computing host:
2018-06-10T17:00:05.454Z|00012|dpif(handler10)|WARN|system at ovs-system:

tcp(src=48982/0,dst=12345/0), tcp_flags(0/0),
actions:ct(commit,zone=5037,mark=0x1/0xffffffff)
The output of dmesg on the computing host is:
[ 4966.042532] openvswitch: netlink: Unexpected mask (mask=a201b8,
allowed=7bb05ac)
I ask for help to identify the possible error.
thankful
William Sales
