Re: [Users] Abysmal network performance inside hypervisor node
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 )

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.

Infiniband hardware address can be incorrect! Please read BUGS section in ifconfig(8).
