[ovirt-users] Adding Infiniband VM Network Fails

[clint at theboggios.com]

Good Day;

I am trying to add an infiniband VM network to the hosts on my ovirt 
deployment, and the network configuration on the hosts fails to save. 
The network bridge is added successfully, but applying the bridge to the 
IB1 nic fails with little information other than it failed.

My system:

6 HV nodes running CentOS 7 and OV version 4
1 Dedicated engine running CentOS 7 and engine version 4 in 3.6 mode.

The HV nodes all have Mellanox IB cards, dual port. Port 0 is for iSCSI 
and NFS connectivity and runs fine. Port 1 is for VM usage of the 10Gb 
network.

Have any of you had any dealings with this ?
