Some details, step by step.
Install OS, Install OFED,
Create Bond for ib0 and ib1 - bond0
Set IP to bond0, and MTU to 65520.
Add Host to oVirt Cluster
At this moment of time everything is Fine.
Next step.
Assign New network to bond0, oVirt set MTU to 1500, and ... That is all. No storage, No
IP. I can't change MTU to 2044 or 65520 and can't assign IP to IB interface.
From system perspective i do understand why.
oVirt Creates new bridge using brctl - and brctl didn't support IPoIB, but how can i
change it back to original config?
