I'm a beginner and I guess it is a place for help.

 Just to add, since it seems a common problem getting round some of the

Just consider the network if the guest were not virtualised, but a real 
machine, and the bridge were a real switch sat on your desktop. You'd need a 
means of configuring the networking on the "guest" (eg static config or DHCP), 
and a means of getting it's traffic to-from the outside world (typically by 
means of a router).

Now you are going to take those separate pieces of hardware and roll them up 
into a virtualised setup. The switch turns into a virtual switch (a bridge* in 
Linux networking terminology), the computer turns into a virtualised guest, and 
the router turns into ? At home I run a separate guest as a two port router, 
but you can put it's functions into the Dom0 config.

So from the PoV of the guest, it's just connected to a network switch. Nothing 
magical changes, and it's IP config is managed in just the same way as the real 
machine.
