Doc Type:	Bug Fix
Doc Text:	Previously, creating a new bond used the balance-rr mode by default and this could lead to connection issues. Now, active-backup mode is used by default for newly created bonds as active-backup mode does not increase the available bandwidth but is safe to use in any setup.

Description Fabian Deutsch 2015-06-18 02:09:37 EDT

Description of problem:
Previously balance-rr was used as the default bonding mode. But this could lead to problems with Vm networks, especially during the hosted-engine setup. To prevent this problems (bug 1230638).

The default should be active-backup which is a safe start.

Comment 2 wanghui 2015-10-29 05:56:08 EDT

Test version:
rhev-hypervisor7-7.2-20151025.0.el7ev
ovirt-node-3.3.0-0.18.20151022git82dc52c.el7ev.noarch

Test steps:
1. Clean install rhev-hypervisor7-7.2-20151025.0.el7ev
2. Create bond and check the default mode

Test result:
1. After step2, it gives "mode=active-backup miimon=100" as the default options.

So this issue is fixed in ovirt-node-3.3.0-0.18.20151022git82dc52c.el7ev.noarch. Change the status to verified.
