An Available, But Older, DHCP Agent Version Causes dnsmasq to Fail
An older version of dnsmasq can cause DHCP (or the DHCP agent) to generate IP addresses for VMs, but not actually assign them to the VMs. The minimum version dnsmasq that should be used is 2.65.
When using YUM, the older version of dnsmasq might be included in the repository. (Related to 20353846).
Workaround:
1. Check for the older version by issuing rpm -qa | grep dnsmasq If a version earlier than 2.65 is present, go to the next step.
2. Upgrade to at least DHCP version 2.65 for Oracle Linux 6:
rpm -Uvh dnsmasq-2.65-1.el6.rfx.x86_64.rpm

Commands sent from the ES2 Mechanism Driver to OFM fail when switch is under load
When the ES2 switch is under load or when there are many concurrent requests on OFM, then the ES2 OFM Plugin will time out and cause API requests to fail. This means that OpenStack requests such as adding a VLAN or adding a port to a VLAN will fail.
Workaround:
Retry OpenStack requests again.
