Hello,

I have two questions about networking with DomUs.
I searched the net a bit how to control how much bandwidth a xen DomU can use 
on a network device. Although my Dom0 has 4 network interfaces I'd like to 
limit some Dom0s so that they can't use the full bandwith of their assigned 
interface (just like with limiting their memory or CPU). How could I do that? 
Is there a way in Xen or do I have to use external tools?

Second question is about "virtual switches". Is it possible to connect several 
DomUs via network even if they have no physical device assigned to them? Or 
does every DomU need a bridge connected to a physical device in the Dom0?

Thanks,
Reinhard
