In a beta release of Red Hat Enterprise Virtualization 3.1, operations involving logical networks with custom MTUs failed.
Now, logical networks with custom MTUs behave the same way as those without custom MTUs.

When changing something in the BOND (Mode, add or remove nics from BOND) the MTU configuration on the ifcfg-ethX are resets. Steps to Reproduce: 1. On SetupNetworks create BOND and attach network with MTU 5000 to it. 2. On SetupNetworks add another nic to the BOND. Actual results: The MTU=5000 are deleted from ifcfg-ethX files Expected results: The MTU=5000 should be on the ifcfg-ethX files When attaching two networks with custom MTU to the same nic the operation fails. Steps to Reproduce: 1. Create two networks with custom MTU and attach them to cluster 2. Open SetupNetworks and attach the networks to nic > apply. Actual results: The operation failedץ Expected results: Should succeed, the networks attached to the nic. Failed to detach bridge-VLAN-MTU network from nic
Steps to Reproduce:
1. Create bridge-VLAN-MTU network and attach it to cluster.
2. Open SetupNetworks and attach the network to nic > apply.
3. Open SetipNetwork and detach the network from the nic > apply.
Actual results:
The operation failed
Expected results:
Should succeed, the networks detach from the nic

IOError: [Errno 32] Broken pipe
the following patches solve most of the issues raise until now: http://gerrit.ovirt.org/7323 http://gerrit.ovirt.org/7360 comment 4 is still on the TODO list. comment 4 solved by http://gerrit.ovirt.org/#/c/7464/2 When adding non_vm network with lower MTU from the one that already configured on the BOND the non_vm MTU is set to the BOND and to the eth of the BOND. The higher MTU value should be on the nics and on the BOND. Steps to Reproduce: 1. On SetupNetworks create BOND and attach network with MTU 9000 to it. 2. On SetupNetworks attach non_vm network with MTU 5000 to the BOND. Actual results: BOND and eth of the BOND now have MTU 5000 Expected results: BOND and eth of the BOND should have MTU 9000 Tested on: vdsm-4.9.6-31.0.el6_3.x86_64 rhevm-3.1.0-14.el6ev.noarch All scenarios was fixed except "Comment 9" see bug - https://bugzilla.redhat.com/show_bug.cgi?id=852052 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
