<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi Ernest,
<div><br>
</div>
<div>we have similar issues with IPoIB. To fix it we use VDSM hooks:</div>
<div><br>
</div>
<div># cat /usr/libexec/vdsm/hooks/before_vdsm_start/network.sh</div>
<div>...</div>
<div>
<div>ethtool -K ib0 tso off 2>/dev/null</div>
<div>ethtool -K ib1 tso off 2>/dev/null</div>
</div>
<div>...</div>
<div><br>
</div>
<div>Nevertheless this is similar to running self defined init scripts.</div>
<div>But at least I have a well defined location to put those fixes into.</div>
<div><br>
</div>
<div>Best regards.</div>
<div><br>
</div>
<div>Markus</div>

<div>Hi, is there a way of setting eth parameters for hypervisors? My freebsd instance has terrible performance when these are enabled. Currently I run these on all hypervisors manually.<br>
<br>
<pre class="pre codeblock">ethtool –K vnet0 gro off
ethtool –K vnet2 gro off
ethtool –K vnet0 lro off
ethtool –K vnet2 lro off</pre>
