Xen users - Aug 2005 - promiscous mode on all interfaces?

Hi folks,

the standard config uses bridging with promiscous mode for eth0 
(understandable) and the vifs (why that?).

Does that mean that EVERY vif receives EVERY packet crossing the bridge 
- even those packets destined for other domains? Documentation compares 
bridging to "a cross over cable between virtual machine and domain0" 
which would then be quite wrong.

Thanks for any help to understand.

Dirk

For the vifs on dom0 side, right?

They shouldn''t receive every packet because the bridge should
automatically
forward packets to the right vif, in the common case.  I imagine setting them 
promiscuous is part and parcel of avoiding them having a MAC address: the MAC 
the bridge sees is that of the guest.

This is an educated guess, since I generally stay clear of the networking 
config!

Cheers,
Mark
