Then I'm also out of ideas. You could take al look at the options in /etc/vdsm/vdsm.conf ( information at /usr/share/doc/vdsm-*/vdsm.conf.sample ) On Wed, Dec 11, 2013 at 2:48 PM, Markus Stockhausen <stockhausen@collogia.de> wrote:

I'm just wondering if the tested interfaces are bridged because I've seen some issues with network througput and bridged interfaces on my local system (F19).
Basically, if an IP is configured on the bridge itself ( in oVirt this is the case if the network is configured as a VM network ) latency goes up and throughput goes down.
Can you rule this one out by using an unbridged interface?
I see. But my storage infiniband network is working without a bridge. That was the mounting network device of my initial mail. So with (ovirtmgmt) and without bridge (infiniband) I have the same problem.
