<div dir="ltr">Hi,<br><br>If I understood correctly, this operation does not incur a long downtime. <div><br></div><div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;display:inline">To setup the bond, first y</div>ou'll need to select the relevant host, select <b><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;display:inline"></div>Network Interfaces</b> and click <b><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;display:inline"></div>Setup Host Networks</b>. At this step, you should be presented with <b><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;display:inline"></div>NIC0</b> (eth0?) connected to <b><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;display:inline"></div>ovirtmgmt</b>, and a standalone (and possibly down) <b><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;display:inline"></div>NIC1</b> (eth1<div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;display:inline">?</div>).

You'll have to repeat this for all hosts you'll be configuring the new bond... All network downtime will be the total time of bringing down eth0, creating bond0 and bringing up bond0 - no more than a fraction of a minute normally. And this will only effect the guests on that particular Host, not the whole cluster.</div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small">A little side note on migrating from a single nic to a bond: if you plan to add more VLAN tagged virtual networks to your new bond, keep in mind that ovirtmgmt should also be VLAN tagged - you can not mix tagged and untagged networks on a single bond. </div><br></div></div><div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small">Regards,</div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, May 18, 2015 at 5:58 PM, Christophe TREFOIS <span dir="ltr"><<a href="mailto:christophe.trefois@uni.lu" target="_blank">christophe.trefois@uni.lu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Dear all,
<div><br>
</div>
<div>How I would go about in an existing setup with 1 NIC and 1 vNIC ovirtmgmt, to add a second NIC, team them up (bonding) and then assign that one to ovirtmgmt without too much downtime?</div>
<div><br>
</div>
<div>Does anybody have some experience on that?</div>
<div><br>
</div>
<div>Thank you for your help,</div>
