Betreff: Re: [Users] Abysmal network performance inside hypervisor node=
=0A=
=0A=
I'm just wondering if the tested interfaces are bridged because I've=0A=
seen some issues with=0A=
network througput and bridged interfaces on my local system (F19).=0A=
=0A=
Basically, if an IP is configured on the bridge itself ( in oVirt this=0A=
is the case if the network=0A=
is configured as a VM network ) latency goes up and throughput goes down.=
=0A=
=0A=
Can you rule this one out by using an unbridged interface?=0A=
=0A=
I see. But my storage infiniband network is working without a bridge.=0A=
That was the mounting network device of my initial mail. So with=0A=
(ovirtmgmt) and without bridge (infiniband) I have the same problem.=0A=
