Description Fabian Deutsch 2015-06-18 09:38:56 UTC

Description of problem:
Some bond modes cause problems in VM networks, see bug 1094842.
For hosted-engine this is especially important, because a bad bond mode can break PXE booting the VM (bug 1230638).

he-setup should check the bond mode (if a bond is used) and warn the user in case that a bond mode is used, which is known to be unsafe.

Comment 1 Sandro Bonazzola 2015-06-19 09:14:53 UTC

Just for avoiding to dig into other bugs:
interfaces using bonding modes 0, 5 and 6 must fail validation when selected for creating the bridge.

Comment 2 Sandro Bonazzola 2017-04-13 06:31:13 UTC

Marcin, any check done by VDSM when creating the bridge with setupNetworks?

Comment 3 Nikolai Sednev 2017-09-28 09:30:11 UTC

Got appropriate warning message for bond type 0:
[WARNING] Bond bond0 is on mode 0, modes ('0', '5', '6') are not supported
Please indicate a nic to set ovirtmgmt bridge on: (enp3s0f1, eno1, eno2, enp3s0f0) [enp3s0f1]:

for bond type 5:
[WARNING] Bond bond0 is on mode 5, modes ('0', '5', '6') are not supported
Please indicate a nic to set ovirtmgmt bridge on: (enp3s0f1, eno1, eno2, enp3s0f0) [enp3s0f1]: 

for bond type 6:
[WARNING] Bond bond0 is on mode 6, modes ('0', '5', '6') are not supported
Please indicate a nic to set ovirtmgmt bridge on: (enp3s0f1, eno1, eno2, enp3s0f0) [enp3s0f1]: 

Tested on ovirt-hosted-engine-setup-2.2.0-0.0.master.20170919052946.git896e399.el7.centos.noarch.
Moving to verified.
