Hi all.  Understanding that HVM does not support routed networking in the sense that we're accustomed to with paravirtualized guests, I'm hoping there is some similar use-case scenario I've missed. 
I've got a requirement which calls for routing a /24 to a Xen box; various /29s will be peeled off and handed over to paravirtualized guests.  It would be nice if I could do the same with HVM guests, so that I would not have to put a router in front of the Xen box simply to run Switched Virtual Interfaces for the prefixes assigned to HVM guests.  Keeping in mind that my last in-depth search on this was a couple of months ago (and I could've been looking at year-old notes), have there been any recent advancements in this regard?  Has anyone found a "hack" to use bridged networking in the scenario described for the purpose of "routing" (even if it means I'm limited to the max number of bridges per system (8 if I recall correctly))?  Is there any such thing as "host networking" under modern Xen builds, like there is under VMWare GSX for example?  Thanks in advance.
