Hi all, I testing upgrade from Havana to Icehouse. This is changing a number of networking related things so not sure which is my problem. My goal is to maintain my current production state jumbo frames network.
In Havana production I'm using openvswitch plugin, but not LibvirtHybridOVSBridgeDriver, so tap devices are directly on ovs bridges. I have veth_mtu set in [agent] section of ovs_neutron_plugin.ini and all devices get created with the correct MTU. In Icehouse I've migrated to ML2, still with ovs and added OVSHybridIptablesFirewallDriver so now I have the qbr|qvb|qvo devices as well. I copied the veth_mtu into the [agent] section of ml2_conf.ini (which is what openvswitch-agent init file is sourcing on startup) but all interfaces are being created with standard 1500 MTU. This include the tap devices on the network node for dhcp-agents (which are associated with qbr devices) and the tap,qbr,qvb,qvo devices associated with instances on compute nodes (the OVS devices int-br, eth1-br, etc all have jumbo MTU). Is this my configuration, a bug, or expected behaviour? Strongly hoping for the first option...
