</span>Adding Simone for this, but I think that hosted-engine --deploy does<br>
not know to create bonds, so you better do this beforehand. It does<br>
know to recognize bonds and their slaves, and so will not let you<br>

<br>
</span>You probably meant eth2 and eth3 for the latter bond.<br>
<br>
This is probably more a matter of personal preference than a result of<br>
a scientific examination, but I personally prefer, assuming that eth0<br>
and eth1 are managed by a single PCI component and eth2 and eth3 by<br>
another one, and especially if they are different, and using different<br>
kernel modules, to have one bond on eth0 and eth2, and another on eth1<br>
and eth3. This way, presumably, if some (hardware or software) bug hits<br>
one of the PCI devices, both bonds hopefully keep working.<br>
<br>
Just my two cents,<br>
