One interesting thing I noticed today after looking at the logs from the 'ovn-controller' on the oVIRT nodes, is node1 is logging like crazy, the file is over 1.2GB in size already, seems to be looping like crazy? What should i check to see why it is logging and maxing CPU like this?

Hi Devin, Below is one example of creating dhcp options and associating them with logical ports using ovn-nbctl commands. Please see the links shared by Lance for more details. Lets say you have a network with cidr - 10.0.0.0/24. One example would be $ovn-nbctl dhcp-options-create 10.0.0.0/24

Hi Devin, This blog posting does a good job of explaining how to configure OVN DHCP support: http://blog.spinhirne.com/2016/09/an-introduction-to-ovn-routing.html The ovn-nb man page lists the DHCP options that can be provided, including mtu:

Devin, oVirt does not currently support changing external network mtu from within ovirt (it rather relies on the provider handling this internally). If you are using OVN DHCP (have subnets defined for a network), you can modify the OVN DHCP options directly in the OVN database. I have never
