Hello, There is an option "network_device_mtu" on nova.conf. When tap,qvo,qbr bridges are setup, it will use this setting to set MTU. However, from my experience, there is no setting to set br-tun, br-int MTU setting. I need to note that DHCP option will only cause MTU setting inside VMs. You can follow the bug report about setting MTUs on br-int, br-tun interfaces. https://bugs.launchpad.net/neutron/+bug/1419069 Regards, Eren -- System Administrator https://skyatlas.com/ _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
