ok, so, can I change that behaviour?
because, if I have another domU in the same network, it would have a
different gw, right?

The gateway is the dom0 (or driver domain) address right?

That is generally a static address for each dom0 (i.e. physical machine). I would expect that the domUs on the same box would have the same gateway and the different one have different.

If my understanding is correct you don't even need to worry about the .131 number as that is not the gateway, but just a backend IP. The gateway (presumably the dom0)  is typically just that , a gateway , and not usually addressed directly.
