Here is the output of vdsClient

'bond0': {'name': 'bond0',
'rxDropped': '0',
'rxErrors': '0',
'rxRate': '7.1',
'speed': '20000',
'state': 'up',
'txDropped': '0',
'txErrors': '0',
'txRate': '0.3'},
'ovirtmgmt': {'name': 'ovirtmgmt',

This may very well be a case of
Bug 1120778 - align reported speeds for physical bond and bridge
but I'm not sure when we are going to fix it, since 3.6 vdsm reports absolute
rx/tx values, which lets Engine provide more sensible data to the user.

I have to re-install the machine with 3.6. I will update u after doing the
same.
