sorry to bring this up again but i'm still confused (i know things changed
recently with peth0 and all). so theres no more veth0? whats peth0?
(someone said it was the physical int, i thought that was eth0, eth1,
etc.). Also, i'm using vif-route not bridge:

Anthony, what version/changeset are you running?
Any answer you get is probably true only for a range of changesets.
We're trying to put together some documentation of the networking
stack this week, once we clean up a few issues...
Firstly, you seem to be running in bridged mode - you have all the
infrastructure we create in the default bridge scripts (which we
don't in the default routing setup):
The 0 in the names below is the default, it will be $vifnum,
specific to your local script changes, otherwise...
Domain0 network stack
^^
||
||
eth0 [local virtual interface]
^^
||
|| local traffic intended for domain0
||
||
xen-br0 [bridge] <===> vif0.0 [virtual dom0] <=======> eth0 [domU virtual nic]
||
||
|| external traffic
||
VV
peth0 [real, physical interface]

--XX ------------ NETWORK -----------------
I'm trying to put together some documentation of the networking
stack this week, once a few issues get cleaned up. I started on
this lastweek but the stack has been a bit volatile (someone else
floated something similar more recently with some more text)..
Hope that helps for now..
thanks,
Nivedita
