<div>Network problems was solved after changing Bond mode (and
it's strange. I have to investigate around qemu-kvm, cento 7.2
and switch firmware ), but broker problem still exist. If I
turn on the host, ha agent start engine vm. When engine VM is
up, broker strats to send email. Now I haven't here detailed
logs.</div>
