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?
Below link with my settings:

What do you mean that it must be less?
If you want to have jumbo frames, you need your node to support it (HW
support) and the media that connects the nodes to support it as well.
Then, you can go to the oVirt Engine, network section and set it
(ovirtmgmt?) to whatever mtu you like (9000?).
If you have vlan/s defined on the bond which are not controlled by oVirt,
then you need to do that manually.
