[ovirt-users] Virtual networks in oVirt 4.2 and MTU 1500

I have a not big cluster on oVirt 4.2. Each node has a bond, that has several vlans in its turn. I use virtual networks OVN (External Provider -> ovirt-provider-ovn). While testing I have noticed that in virtual network MTU must be less 1500, so my question is may I change something in network or in bond in order everything in virtual network works correctly with MTU 1500?
