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