I'm running ovs (1.4.2) for xen bridging from debian 7.1. The physical interface is configured to the max possible MTU of 9216, because there's one ovs port configured for san access with a VLAN tag and MTU of 9190 that's used by open-iscsi initiator exclusively. The machine's main/management interface is configured to default MTU 1500.
If I start a VM, its VIFs will be created with MTU=1500. When they are added to the ovs bridge, subsequently all non-physical interfaces will be reset to MTU=1500, including the (for common network traffic unused) san port. The same will happen if I further reduce one interface MTU manually; its setting will propagate to all ports. This appears unexpected to me and is undesirable. How can I avoid this?
