Description of problem:
at the moment (version 3.5) there is a limitation in Setup Networks which requires MTU to be the same in case of combination of bridgeless network and VLAN on single interface. This should be changed to allow for different MTUs as long as MTU on physical interface >= MTU on VLAN with highest MTU
Stepwise:
1) create networks
on engine create new new VLAN tagged network with default MTU 1500
Networks -> New -> name: VLAN162, enable VLAN tagging: 162
on engine create new new nonVM(bridgeless) network with MTU 2000
Networks -> New -> name: bridgeless, VM Network: False, MTU: custom: 2000
2)
Hosts -> your host -> Network Interfaces -> Setup Networks -> attach VLAN162 and bridgeless networks to em2
confirm dialog
3) result
Error while executing action:
dell-06:
• Cannot setup Networks. The following Logical Networks do not have the same MTU value: [bridgeless(2000), VLAN162(default)].
4) expected result
this should go through if MTU of bridgeless is higher or equal MTU on VLAN with highest MTU

Target release should be placed once a package build is known to fix a issue. Since this bug is not modified, the target version has been reset. Please use target milestone to plan a fix for a oVirt release.
Dan, no we don't, please see --> BZ 1242227
You can't approve operation if the MTU of the networks on a single NIC are not equal.

m2(2000).
