Hi,<BR>
<BR>
Just found the problem / solution.<BR>
<BR>
<A HREF="http://www.novell.com/support/kb/doc.php?id=7007658">http://www.novell.com/support/kb/doc.php?id=7007658</A><BR>

<A HREF="https://bugzilla.redhat.com/show_bug.cgi?id=518531">https://bugzilla.redhat.com/show_bug.cgi?id=518531</A><BR>
<BR>
It's the LRO activated on bnx2x driver.<BR>
<BR>
After the reboot the LRO comes activated, after reconfiguring the bond the LRO is deactivated.<BR>
<BR>
So i created /etc/modprobe.d/bnx2x.conf with: options bnx2x disable_tpa=1<BR>
<BR>
and everythink is ok now after reboot.<BR>
<BR>
Best regards,<BR>
Ricardo Esteves.<BR>

Hi,<BR>
<BR>
I also noticed this on /var/log/messages while the problem was happening (i was downloading a file in the VM from the web):<BR>

Perhaps you can send pastebin of a 'vdsClient 0 getVdsCaps' (or 'vdsClient -s 0 getVdsCaps' if the first doesn't work)
from the host when the bond is slow, and one after you break and create it again?
if you don't have vdsClient command you can 'yum install vdsm-cli' and it should be available.
