During the start of the deployment with ovs2.9, the OVS-DPDK is enabled using first-boot before applying the kernel arguments and rebooting. This will cause vswitchd service to fail initially, but later when the kernel arguments are applied and the node has been rebooted, vswtichd will run as expected with DPDK enabled. The failure messages at the initial stage before the reboot can be ignored.

The new iptables version that ships with RHEL 7.4 includes a new --wait parameter. This parameter allows iptables commands issued in parallel to wait until a lock is released by the prior command. For OpenStack, the neutron service provides the iptables locking but only on the routers level. As such, when processing routers (for example, during a fullsync after the l3 agent is started), some iptables commands issued by neutron may fail because they are experiencing this lock and require the --wait parameter that is not available in neutron yet. Any routers affected by this will cause malfunctions of some floating IPs, or some instances may not access the metadata API during cloud-init. We recommend that you do not upgrade to RHEL 7.4 until neutron is released with a fix that adopts the new iptables --wait parameter.
