[ovirt-users] How to fix wrong speed of the Infiniband Interfaces?

If you are speaking about ib0 and so on this will be fixed with 3.5. The interfaces will then be advertised as 10Gbit.

Hi,
I am using ovirt 3.4.4-1.
On the hosts I have 1Gbit(eth),10Gbit(eth) and 40Gbit(QDRInfiniband) interfaces.
ib interface is used for the VM migration and iscsi disks.
If I go to the network interfaces I can see right speed for eth cards.
Unfortunately the IB interface speed is detected as 0b/s.
This causes very hi load information on vm migrate face. Which is not true. IB can up to 2GB/s but already on 200MB/s load the hosts interfaces are overloaded.
Where can I put the correct speed of IB interface?
Thanks,
Arman.
