Open Stack

Hi,

I have a small Openstack kolla-ansible deployment running on a bond 2x 25Gbits/sec network and jumbo frames MTU 9000. I was trying to setup kolla-ansible to be aware of my physical network configuration but I could not find any document related to this.

I also tried to make this changes manually modifying neutron.conf and ml2_conf.ini files on control and compute nodes (https://docs.openstack.org/neutron/pike/admin/config-mtu.html) and rebooted the neutron containers but new vms still has MTU 1450.

Questions:

Does anyone knows how to configure kolla-ansible to do what I want?
Does anyone has a tip about how to configure MTU 9000 on a Opestack kolla-ansible deployment?

Thank you very much
