Hello,
I've a problem, all my ovirt hosts and vms are linked with a bonding mode

ping vm from different subnet.
Eveything is okay if I don't change bond link interface。When I unplug
Currently Active Slave eno1,bond link change to eno2 as expected but vm become
unreachable until external physical switch MAC Table ageing time expired.It
seems that vm doesn't sent gratuitous ARP when bond link change. How can I fix
if?
vm os is Centos 7.5
ovirt version 4.2 also tested.
