I am using devstack-train version.
Can you guys tell me which source  file or function should I look when I get mtu size in the network-info but not in the libvirtxml parsed like below log

I checked the solution mentioned in [ https://bugs.launchpad.net/nova/+bug/1747496] and the source code which it said to add is already in my nova code.

Anyone have any suggestions?
