Hello, thanks for the explanation, but I did'nt find any reason about=20
incompatibility between mode 0 and bridge... Can you give me some=20

But for my own, I have several single kvm hosts that support bridge over=20

So, someone can share his experience about this kind of detail?

The balancing on 802.3ad only occurs for different network flows
based on a hash of source and destination MAC (or can be made to
add IP addresses into the calculation). A single flow will only
use a single NIC in ad mode.
